Close Circuit Television is becoming increasingly popular as a deterrent against crime and DIV Security offers a wide range of CCTV options to suit your budget and requirements.
Stand Alone Recording
Digital recording on to a high capacity hard disk is available for multiple cameras. allowing easy playback and recordings. They are small, compact, and there is no need to change tapes.
This system allows the user to access live video recording from anywhere in the world as well as reviewing and playback previous recordings. Speak to our engineer for more details on the best solutions available to you.
What is CCTV?
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores.
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room; when, for example, the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital Video Recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts).
Surveillance of the public using CCTV is particularly common in the UK, where there are reportedly more cameras per person than in any other country in the world. There and elsewhere, its increasing use has triggered a debate about security versus privacy.
One of the recent developments in Design of CCTV systems is Integrated Systems. These Systems consist of a Digital Video Recorder (DVR), a display monitor, and a built in Network card. Integrated systems look exactly like an LCD monitor. They can be used as simply a monitor, although their compact size makes them attractive for CCTV users.
Integrated Systems also have USB outlets so that Video Clips and Recordings can be moved out onto a USB key or External Hard drive and then later transferred on to a DVD if needed. Police investigations after a crime require that a copy of the CCTV recording be available to investigators.
Integrated Systems that come with a Built in Network Card allowing users to connect remotely from the internet and view exactly what their cameras are viewing. This allows monitoring from anywhere in the world by simply having a computer and an internet connection. This feature is very similar to that of IP cameras. A famous incident is that a lady was able to watch her house get robbed and contacted police directly from her office at work.
Popularity of Integrated Systems is increasing among small business owners and small offices. These users require a solution to their security needs that does not involve complex hook ups and difficult user interface.
We at D.I.V. Security Systems providing CCTV installations, repairs and maintenance in London and home counties.
We supply and install Ip CCTV systems (1080P – full HD quality), as well as mid range conventional systems.

IP based cameras are the future. They work by turning images and audio into data then transmitting this data over a network or Internet connection. The ultimate benefit of this over analogue CCTV systems is greater flexibility, better performance.
IP CCTV systems do not require local recording, they can transmit their images across Local Networks, the Internet and Wide Area Networks to a central location, where they can be recorded, viewed and managed.
IP CCTV systems convert all images to data and have no theoretical limit to resolution, providing the relevant bandwidth to transmit the images exists. Our IP cameras offer especially high detail precision with Megapixel resolution, at least 3x better quality than standard analogue cameras. These are very affordable, with pricing equivalent to analogue CCTV systems.
IP CCTV systems run over existing IP networks, this makes wiring IP CCTV systems simple, causing less disruption, reducing the time required to install them and minimising unsightly cables. If POE (Power over Ethernet) IP cameras and networks are used then the IP CCTV cameras do not even need separate power, they can be powered via the network cable.

An analogue CCTV system is designed to record security cameras locally only. This means that if you have 2 or more premises, then each will require a Recording Device.
Analogue CCTV systems are based on PAL analogue technology and have a maximum possible resolution of just 414,720 pixels. This limits the amount of evidential quality images a single analogue camera can supply, or put another way the size of area it can watch. Resulting in an increase in the number of cameras required to watch an area.
Analogue CCTV systems have their own proprietary cabling. Each camera has to be wired back to the DVR or Monitor using RG59 cable or similar Video Signal Cable and each camera has to be connected to a power source.
Analogue CCTV systems are excellent value for money, and though the general consensus is that IP CCTV is more expensive, this is not true for every scenario. IP CCTV represents an investment in to a future technology and infrastructure, whereas analogue CCTV systems are based on old technology contact us now.
