Uses oF CCTV cameras in kenya
Crime prevention
CCTV has played a crucial role in tracing the movements of suspects or victims and is widely regarded by anti-terrorist officers as a fundamental tool in tracking terrorist suspects in kenya and whole world as whole. Large-scale CCTV installations have played a key part of the defenses against terrorism since the 1970s. Cameras have also been installed on public transport in the hope of deterring crime.
A more open question is whether most CCTV is cost-effective. While low-quality domestic kits are cheap the professional installation and maintenance of high definition CCTV is expensive. Gill and Sprigs did a Cost-effectiveness analysis (CEA) of CCTV in crime prevention that showed little monetary saving with the installation of CCTV as most of the crimes prevented resulted in little monetary loss. In Singapore, since 2012, thousands of CCTV cameras have helped deter loan sharks, nab litterbugs and stop illegal parking, according to government figures.
Crime solving
CCTV can also be used to help solve crimes. In London alone, six crimes are solved each day through CCTV footage. Sometimes, footage from CCTV cameras of citizens can even be used for this purpose.
Traffic flow monitoring
Vehicle traffic
Many cities and motorway networks have extensive traffic-monitoring systems, using closed-circuit television to detect congestion and notice accidents.
Pedestrian traffic
In the Philippines, barangay San Antonio used CCTV cameras and artificial intelligence software to detect the formation of crowd during an outbreak of a disease. Security personnel were sent out whenever a crowd was formed at a particular location in the city.
Sporting events
Many sporting events in the world use CCTV inside the venue for fans to see the action while they are away from their seats. Automatic gate system send the feed to a central control center where a producer selects feeds to send to the television monitors that fans can view. CCTV monitors for viewing the event by attendees are often placed in lounges, hallways, and restrooms. In a trial with CCTV cameras, football club fans no longer needed to identify themselves manually, but could pass freely after being authorized by the facial recognition system.
Use in private homes
Many home owners now choose to install CCTV systems on their own homes. CCTV cameras are an effective deterrent to criminals as it increases the risk of criminals getting arrested because they could be identified through the camera footage. Most criminals will scout through affluent suburbs looking for the easiest house to break into. Having an obvious CCTV system, or another security alarm, makes the house appear to be a more difficult target so the criminals will likely move on to the next house. Modern CCTV systems can be monitored through mobile phone apps so it is possible to view live footage of your house from anywhere you have internet coverage. Some systems even provide motion detection so when movement is detected, an alert can be sent to your phone.

Every thing you need to know about CCTV cameras
HD VIDEO IS SUPERIOR.
There is no comparison between HD video and older analog technology. HD video is much higher resolution and displays far better detail and clarity. In-fact, you can expect our HD cameras to be at least 3-5 times sharper than standard analog cameras. This is because HD cameras are measured in megapixels. Each megapixel is comprised of 1 million pixels or dots on a screen. 1MP and above is considered high definition which is the equivalent of a 720p digital broadcast signal. Full HD television is broadcasted at 2MP or 1080P. A 4K Ultra HD video broadcast is equivalent to 8MP. The higher the megapixel counts the sharper the image. One great benefit of HD cameras is that you can digitally zoom or blow up an HD picture and the integrity of the image will remain largely intact rather than appearing pixilated or blurry like the older analog cameras.
DVR VERSUS NVR.
There are 2 types of HD security camera technologies; HD over Coax and IP based. A recorder that supports HD over coaxial cable is called a digital video recorder (DVR). IP cameras connect to a (NVR) network video recorder using Ethernet or network cable. Both DVR and NVR units provide the same basic functionality. Either can be used to view live or recorded video and also to view your cameras remotely on a Smartphone, tablet or computer. The main differences would be the type of cable used to connect the cameras. Also, it is important to note that HD over Coax recorders is backwards compatible for older analog cameras. In other words, you can use both HD cameras as well as any existing analog cameras with our HD over Coax digital video recorders.
IP NETWORK CAMERA SYSTEMS.
Many new customers are interested in IP cameras. We offer 2 IP camera product lines; Green-line and Blue-line. You should always match products with the same color code for the best compatibility and overall user experience. Our Network Video Recorders are able to display Ultra HD images up to 8mp or 4K. IP cameras are run using CAT5, CAT5e or CAT6 Ethernet cable. All of our IP cameras are Poe (Power over Ethernet) meaning that both power and video are transmitted over a single cable for very simple installation. Standard IP cameras can be run up to 325ft. We offer additional hardware such as repeaters and switches for customers who require further cabling. A unique feature of our Green-line (Sure Vision TM) IP camera line is the ability to transmit both power and video over 1,000ft using pure copper Ethernet cable.
HD OVER COAX SYSTEMS.
HD over Coax cameras are run using traditional coax cable with BNC video connectors. Our Digital Video Recorders can also produce ultra HD images up to 8mp or 4K, and are also compatible with older analog cameras. The most common type of cable used is RG59 Siamese cable. The term Siamese means there are actually 2 cables (power and video) running side by side that can be pulled apart. This is important because HD over Coax cameras are not powered from the recorder. Rather, HD over Coax cameras can be powered using an individual power adapter or a multiple output power when running multiple cameras. HD over Coax is extremely beneficial when a customer has existing analog infrastructure in place and wants to also add HD cameras. Another benefit of HD over Coax is that video can be transmitted well over 1000ft distance. Our digital video recorders support all of the HD over coax technologies.
We carry many different styles of cameras.
We carry many different styles of cameras. A lot of people like the bullet style cameras due to their sleek housing. Other people prefer a dome style for their discreet, low profile and vandal-proof design. A large majority of the cameras we offer are fully weatherproof for indoor or outdoor use. The size of the camera lens will determine its viewing angle. Our widest lens size is 2.8mm and will produce a 110 degree super wide angle which is good for covering the entire immediate perimeter. A popular 3.6mm lens will display a 90 degree wide angle. Our most popular lens size is the 3.6mm which offers a 90 degree wide angle. Customers like wide angle cameras because they offer the most bang for the buck. However, if you need to focus on an object that is much further away then you will require a more powerful lens such as 8mm, 12mm or even a 50mm or 100mm lens for good close up images of objects that are over 100ft or even 200ft away. Many of these cameras offer a varifocal lens that you can adjust to achieve the perfect angle. Better yet, many of the varifocal cameras have a motorized lens so you can simply adjust the angle directly from your recorder or remote device. In short, there is always going to be a compromise between the width of the angle and the distance you can see. The perfect solution may sometimes be a combination of wide angle and varifocal cameras. A growing branch in CCTV is internet protocol cameras (IP cameras). It is estimated that 2014 was the first year that IP cameras outsold analog cameras. IP cameras use the INTERNET PROTOCOL (IP) used by most local area network (LANs) to transmit video across data networks in digital form. IP can optionally be transmitted across the public internet, allowing users to view their cameras remotely on a computer or phone via an internet connection. For professional or public infrastructure security applications, IP video is restricted to within a private network or VPN. IP cameras are considered part of the Internet of things (IoT) and have many of the same benefits and security risks as other IP-enabled devices Our IP systems are currently used in business of all sizes, government applications, and homeowners seeking a high quality, commercial grade solution. Our SUREVISION camera comes with a 3 year warranty and unlimited technical support for the life of the product. These cameras make a perfect solution for any high end security application. IP cameras for business security or home security have quickly advanced and now offer a wide range of premium features, including incredibly detailed 1080p and 4K security footage, revolutionary night vision technology with long-range viewing, in addition to weather-resistant and vandal-proof housings to ensure safe outdoor use.

Color VU Turbo HD cameras
provide bright color video images 24/7, even in the lowest-light conditions. This powerful ability to capture details in low lighting comes from two specific breakthroughs in hardware technologies: advanced lenses and high-sensitivity sensors. In contrast to conventional lenses, ColorVu lenses are equipped with a super-aperture, reaching up to F1.0, which allows more light to enter the lens so that imaging brightness can be increased. The high-sensitivity sensor demonstrates a new light-collection structure that vastly improves the utilization of light. With brighter, more colorful video images, Hikvision customers are protected against security Breaches, even when they happen at night.
Hikvision AcuSense family
Small and medium-sized businesses (SMBs) have many of the same surveillance and security requirements as larger organizations. They need to identify and react to perimeter breaches in real time, and they need to automate footage searches to save time for their security teams. Incorporating eleven different DVR models, Hikvision AcuSense family uses the latest deep learning technologies to enhance object detection. Specifically, Hikvision AcuSense Turbo HD DVR detects vehicles or humans; it filters out false alarms triggered by animals, leaves, and other insignificant objects, and minimizes costly, time-consuming manual checks. As an additional benefit, Hikvision AcuSense Quick Target Search feature identifies and extracts footage of humans and vehicles from vast video datasets automatically, saving staff from searching through massive datasets. Analog security products have been popular among installers and customers for many years. Analog solution architecture is much simpler, making it easier to set up and maintain; and to fulfill the same security needs, an analog solution is usually more cost-effective than an IP solution. Ever since their launch in 2013, Hikvision’s Turbo HD Series analog products have been widely applauded for their amazing abilities. The Turbo HD line transforms analog CCTV video into high quality, high-definition surveillance. The latest Turbo iteration – Turbo HD 5.0 – takes everything a step further, employing AcuSense – a smart VCA technology based on deep learning algorithms – and ColorVu – 24-hour chromatic imaging.
Wireless security cameras
Many consumers are turning to wireless security cameras for home surveillance. Wireless cameras do not require a video cable for video/audio transmission, simply a cable for power. Wireless cameras are also easy and inexpensive to install but lack the reliability of hard-wired cameras. Previous generations of wireless security cameras relied on analogue technology; modern wireless cameras use digital technology which delivers crisper audio, sharper video, and a secure and interference-free signal
Talking CCTV
pilot scheme for what is now known as "Talking CCTV" was put into action; allowing operators of CCTV cameras to order offenders to stop what they were doing, ranging from ordering subjects to pick up their rubbish and put it in a bin to ordering groups of vandals to disperse. In 2005, Ray Mallon, the mayor and former senior police officer of Middles rough implemented "Talking CCTV" in his
CCTV FAQ frequent asked questions in kenya
How does infra red work on a CCTV camera
The ability to film in low light conditions or even complete darkness is essential for many CCTV applications. Part of the that ability is down to using the right electronics which are sensitive enough to work in low light, the other tool used is infra red or IR lighting. We have a guide to infra red in our camera buying guide. Infra red light isn't visible to the human eye but CCTV cameras switch to black and white as light levels fall and can film the IR light spectrum. This means that to the camera its like shining a torch. IR has to bounce off something but providing there is a hard surface to reflect the infra red your camera is able to see in the dark.
Previously cameras had separate infra red light lamps bolted onto the side of their housings. It made the whole unit very large and industrial looking. In more recent times cameras have been designed with IR lighting built into them. This greatly reduces their overall size and visual impact. It also reduces cost when compared to modular cameras using separate lighting units. Many people selling CCTV cameras describe them in terms of infra red range. Do not confuse this with the optical range of the camera or the distance at which a camera can record detail. That is determined by the lens. Wider angle lenses will have a shorter optical range, more telephoto lenses a longer range. The IR range is a largely immaterial figure, often made up and is supposed to represent the distance at which the camera's infra red can be detected. In reality the ability of a camera is a combination of the lens, how powerful the IR is and how sensitive the electronics are.
How does motion detection work with CCTV cameras and systems
Motion detected recording is a feature on all our DVR recorders. The DVR monitors camera images and decides when it thinks there is movement. To do this the DVR looks at individual image frames and compares them to the previous one. If it sees differences then motion is assumed to have taken place. It is the DVR not the cameras which is looking for movement.
A DVR isn't as intelligent as you or I and can't differentiate between background movement, changes in light and someone coming to break into your property. To help minimise false triggers it is possible to limit where on the screen the DVR looks for movement and limit this to a small area or a number of areas. You don't have to use the full screen. You can set the trigger area using the set up menu on the DVR, you can also set the trigger area remotely if the DVR is connected to your local network / the internet.
Some people only record footage when motion is detected in an attempt to extend the time footage is stored. We are not big fans of doing this. We would rather see motion triggering being used to create bookmarks within 24/7 recording rather than the sole means of capturing footage. Use it to identify which sections might be important but still have constant footage either side of the trigger.
What do I need for a complete CCTV system?
A CCTV system will be based around a DVR or digital video recorder. CCTV cameras are connected to the DVR using cables and there will be some ancillary items such as a power supply for the cameras.
DVR or digital video recorder
DVR or digital video recorder The DVR is the heart of the CCTV system. It takes all the camera inputs, arranges them on screen for live viewing and also stores footage onto a hard drive for viewing at a later date. Our DVRs record all the cameras regardless of what you are viewing live on your monitor. It is possible to view 1 camera at a time or several camera in various combinations depending on how many channels the DVR supports. We sell 4, 8 and 16 channel DVRs which are suitable for 4, 8 or 16 cameras respectively. They can be combined, so 2 16 channel DVRs could host a 32 camera CCTV system.
Our DVR recorders also support remote access over the internet. You need to connect the DVR to your internet router. This can be done either with a cable, a power bridge adapter which uses your electrical wiring or a wireless network point. Then wherever you are in the world you can view live footage from your cameras, see previously recorded footage, make back ups of important events and even make settings changes to the DVR
The cameras
CCTV cameras are the most important thing to get right and we have devoted quite a bit of space on our website to helping you make the right choice. We are always glad to offer help and advice if you are planning a CCTV system so pick up the phone and give us a call. We can have a look at your property using aerial images whilst talking through your specific requirements and select which cameras will best suit your requirements.
Cables
The cable from the DVR to the camera does 2 jobs. It transfers video from the camera back to the DVR and it supplies 12 volt power to the camera. Video connection is via a BNC connector. If you are using CAT5 cable then the BNC connector will be part of the video balun. 12 volt power connections are 5.5mm jack plugs. At the camera end there is a DC plug, at the DVR end a DC socket into which the 12 volt power supply for the camera connects. For this reason you would normally locate the camera power supply next to the DVR unit. The DVR will be supplied with it's own 12 volt power supply.
Are PTZ (pan, tilt, zoom) cameras better than fixed cameras?
What is a PTZ camera ?
PTZ stands for Pan, Tilt, Zoom. A PTZ camera can be remotely controlled allowing it to move up and down as well as zoom in on potentially important targets. You can also program a tour between pre-set points. In theory PTZ cameras sound great, they can cover large areas and even zoom in when more detail is required
The downsides of using a PTZ camera
PTZ cameras are expensive, certainly good ones are. There are a few low quality products on the market aimed at the bottom end of the DIY market, these should be avoided. However the biggest problem with PTZ cameras is that you need a full time operator to control them. When pointing in one direction they can't see elsewhere. When the camera is moving the image will be blurred meaning you can't get any detail or identify people. So when you set the camera on a tour between preset points the image will be blurred for a large part of the recording.
Infra red illumination is often not fitted to PTZ cameras meaning they are less effective at night. It is possible to find PTZ cameras with effective IR and our PTZ cameras feature zoom sensitive IR which increases brightness as you zoom in, the assumption being you are hoping to see further away. Latency when remote accessing the cameras. When remote accessing PTZ cameras there is a delay between you asking a camera to move and seeing the result of that movement on your remote monitor or computer. This is known as latency and it can make it difficult to accurately control PTZ cameras remotely over the internet.
Consider fitting more fixed cameras
Rather than use a PTZ camera consider fitting more fixed cameras for the same cost as a single PTZ camera. That way you will cover all the views all the time. You also don't need the expense of a full time operator. There are some "self tracking" cameras which identify targets and keep following them, the problem is the image will be blurred when the camera moves and how does the camera know who to track when faced with multiple targets. Thieves often work in gangs. PTZ cameras do have their uses but in the vast majority of cases you are better off using more fixed cameras.
Can you explain the wide range of prices I see for CCTV on the internet in kenya?
Like everything in life CCTV is available at a range of different prices points and quality levels. You can fly on a plane for $500 in economy or you can pay $5,000 to fly on the same plane in a first class suite
The problem with CCTV is a lack of regulation and failure to understand the basic principles means people often sell systems which won't do what they claim. They sell you a first class suite but you board the plane to find yourself squeezed into a small economy seat. Actually its worse than that, they sell you a first class suite to New York but you get to sit on an orange crate whilst the plane flys to Luton.
People selling CCTV tell lies
We set up Havens as frustrated customers. We did our homework, looked at the specifications, listened to the sales patter in kenya and were very disappointed with what turned up. When you know what you are looking at the claims made by people selling CCTV in kenya are appalling. It isn't just the odd seller on ebay, it's rife across the industry. Big national retailers are misleading buyers in an attempt to get their money. When you see a camera with a claimed range of 25 metres you assume it's capable of filming something 25 metres away. You might allow a bit of artistic licence and work on 20 metres to be safe but the reality is it might only have an optical range of 3 or 4 metres.
The specifications retailers use are often not important
Sticking with CCTV cameras as our example retailers often use TVL (television lines) as a determining factor in how good or bad their products are. The number of TV lines has little to do with the quality of a camera, that is more to do with the lens fitted and its optical range. Even if TVL was important retailers rarely quote TVL correctly, they advertise 560TVL cameras as 1000 TVL cameras because they don't understand how TVL is calculated.
Advice and support
We don't just sell boxes. We listen to customers needs, advise them as to the most appropriate equipment and then support them once their purchase arrives. That advice and support is vital but usually lacking at the cheaper end of the market. CCTV isn't difficult once you understand a few basic rules but most people struggle because they are mislead by false claims. Only a tiny proportion of CCTV fitted actually does what it should. We want to ensure you are are one of those small minority who own effective CCTV solutions.
Understanding the range of a CCTV camera
TVL and IR range
People selling CCTV are often very misleading when it comes to CCTV camera range. They normally quote two figures, the number of TVL and the IR range. This might be called the night time range. IR range is a largely made up number based around how far away from the camera Infra red light can be detected. It has nothing at all to do with the effective range at which detail can be filmed.
Optical range
The distance at which detail can be captured using a camera is its optical range. Unfortunately no one every quotes it, they only quote the IR range. The optical range has nothing to do with how many TVL the camera has or how bright the IR is, it all depends on what lens is fitted.
A DVR stores images as tiny dots or pixels. With D1 resolution you get around 400,000 pixels per image frame. With a wide angle lens the pixels spread apart very quickly as you move away from the camera and fewer pixels mean less detail is captured. Conversely a more telephoto lens concentrates the pixels and captures more detail further from the camera. Camera lenses are measured in mm, the smaller the number the wider the angle of view. 2.8mm or 3.6mm would be considered wide angle.
Varifocal cameras
A varifocal camera allows you to manually zoom in or out during installation. This means one camera is able to perform different jobs. It can be set to wide angle or telephoto. This means you don't have to worry as much when buying the camera, you can balance the angle of view and detail captured once it is fitted. You just need to make sure you have the correct lens range, we can help you decide.
With fixed lens cameras you only get one chance, if its the wrong angle you have to replace the camera. For that reason we would always advise buying varifocal rather than fixed lens cameras.
Using CAT5 cable to wire CCTV cameras
In recent years the invention of the video balun has meant CAT5e cable can be used to connect CCTV cameras to CCTV DVR recorders. All the connections can be made using only a screwdriver, no need for special tools or fiddly components. Before you start there are a couple of important things to know.
What components do I need?
Video is transmitted along the CAT5e cable using a pair of video baluns, one at the DVR end, one at the camera end. We sell 2 types of video baluns, Standard definition and High definition designed to be used with our HD 1080P cameras and DVR recorders. Power is transmitted using using screw in DC plugs and sockets. The plug goes at camera end the socket at the DVR end. Locate the camera power supply close to the DVR.
Don't exceed the maximum cable run
The maximum distance video signal can be transferred with our video baluns is approximately 300 metres. If you are using the cable to power a camera as well as transfer video signal then we would suggest a maximum distance of about 50 metres to avoid voltage drop. This assumes you are using 3 pairs of wire for 12 volt supply and 1 pair for video signal transfer as per our images below
Use a colour convention, stick to it and check carefully
It is important to check your wiring carefully. Choose a colour convention and stick to it. In the examples below we have used blue for video signal and solid colour for +ve, white plus coloured stripe for -ve.
You need to run 1 length of CAT5e cable from the DVR recorder to each camera. The cable is going to do 2 jobs. One pair of wires will handle the video signal, the other 3 pairs of wires will be combined to take 12 volt power from the transformer located next to the DVR to the camera.
Wireless CCTV cameras
Each week we speak to a lot of people planning CCTV systems. No two conversations are ever the same but the subject of wireless CCTV and in particular wireless CCTV cameras often comes up. In Electric fence in Kenya offers the ideal solution, no cables to run means installation times are reduced. So why don't we sell wireless CCTV?
Before you buy wireless CCTV cameras or a wireless system read this.
There are a number of problems with wireless CCTV. Firstly it isn't actually wireless, you still need to power the cameras via a cable. Wireless cameras tend to be fairly poor quality aimed at the lower end of the DIY market. The electronics aren't great and you only have a limited choice of lens options. Choosing the correct lens CCTV camera is the single most important factor in determining the overall quality of your CCTV system. Read our camera buying guide to understand what you need to consider when looking at CCTV cameras.
Wireless problems and limitations
The wireless link it's self often causes problems. In Kenya a lot of other devices share the relatively narrow frequency bands allocated to this sort of device. Wireless routers which stream the internet around your home share the same 2.4GHz frequency of many wireless CCTV systems for instance. Microwaves, baby monitors, bluetooth devices, structural building components, cordless telephones, walls and other solid objects are just some of the things which can get in the way of a potential signal.
Hard wired CCTV is best
A wired solution will always give the best results. It might take a little more time to install initially but you only have to do it once. CAT5 cable when used in conjunction with a simple pair of passive video baluns can transmit video signals up to 300 metres without deterioration. Switch to active baluns and that distance increases to an incredible 1,200 metres far in excess of any wireless Camera.
CCTV kit, CCTV kits - CCTV cameras, DVR recorders and accessories
We get asked if we sell CCTV kits a lot and the answer is yes
CCTV systems use several different cameras
Everybody's CCTV needs will be different. Some people want cameras for outside, some for inside. Some cameras need to film overall views whilst others need to film higher levels of detail. Some subjects will be close to the camera, others some distance away. The cameras will also be fitted in a variety of different locations. You begin to see that a one box solution can never provide a good CCTV solution. The most important thing to get right on a CCTV system are the cameras. We have a guide to choosing CCTV cameras elsewhere on the site.
The CCTV kits you see advertised all contain fixed lens wide angle cameras. The single worst thing you can do is use fixed lens wide angle cameras because they spread pixels apart as you move away from the camera and you don't capture any detail. They may claim an effective range of up 20 or 30 metres but the reality will be nothing like that, probably 3 metres in standard definition.
Cables and connections
Cable distances will vary from application to application so the likelihood is whatever cables came in the box would either be too long or too short. In fact pretty much every element of a CCTV system needs to be tailored to the user's needs. All in one box CCTV kits often have unique connectors to that particular kit meaning if you need to change a camera you can't because no one sells equipment with those fittings. The result is everything goes in the bin and you have to buy a completely new system.
Quality
CCTV kits tend to be very poor quality. You don't have a choice in how good or bad each element is, you simply get what's in the box. Because they are sold to a price one box CCTV systems tend to contain decidedly average quality equipment other than the outer box it's self. That will be bright, colourful and contains words such as professional, high quality, razor sharp, pinpoint, high definition and so on. They almost spend more money on the box than the contents!
Buy what you need
We allow you to choose elements of your CCTV system individually to make sure you end up with exactly what you need. Save money in areas where conditions are less demanding, buy the right gear for the job where things get a little tougher or results are more critical.
We still reflect the fact you're not just buying a single camera by including a free power supply when you buy 4 cameras. We fit the hard drive into the DVR recorder, format it and configure the DVR settings free of charge to save you having to wade through a 60 page instruction manual. We also include a good quality warning sign pack should you need one. Remember we are happy to offer free help and advice to make sure you buy the right kit.
