CCTV Systems

Intelligent Security and Fire have been installing, maintaining, and repairing CCTV systems to homes, schools, council buildings, shops, office blocks, surgeries, garages, warehouses and many other types of properties for many years with great success. We can cater for CCTV systems from a simple one camera set-up to a system with hundreds of cameras.

A CCTV system can form an important part of a security plan for domestic, commercial and industrial premises. CCTV provides both a visual deterrent to would-be burglars or vandals and evidence of any incident that may occur. CCTV complements other forms of security, such as Intruder Alarms and Security Shutters.

If you are considering installing a security system on your premises, Intelligent Security and Fire offer a free, no-obligation site survey so that you can find the security solution best fitted to your needs. One of our surveyors will visit the premises and use their expertise and your input to deliver a no-nonsense quote that will encompass labour, parts, and installation.

CCTV Explained

If you purchase a home or commercial CCTV kit, then you are likely to find:

  • The CCTV cameras,
  • A DVR for recording the feed from the cameras,
  • Cables and power supplies,
  • A monitor
All of the above is used to provide a system that may be required by your insurers. The cameras themselves, of course, capture footage, and are the ‘eyes’ of the system. The DVR, a high-capacity hard drive and recorder, stores the video and audio sent to it by the cameras through any connecting cables (if a wired system). The DVR can be used to view stored footage or transfer it.

Types of Camera

There are a number of different kinds of CCTV camera, all employed for differing requirements:

Analogue Cameras

Analogue CCTV cameras are PAL-based cameras with a maximum resolution of 414,720 pixels. Analogue cameras record onto a tape that needs to be changed on a daily basis and be securely stored. Reviewing these tapes mean manual searching is necessary to find the required time. Analogue CCTV systems record from each camera in the system in turn.

HD-SDI CCTV cameras are a type of analogue CCTV camera that can record in high definition. They can be fitted to an existing analogue connection and are used for transmitting uncompressed, unencrypted data at a resolution nearly seven times higher than that which is available using standard analogue CCTV.

ANPR, or Automatic Number Plate Recognition, uses optical character recognition to read vehicle licence plates. It can be used using existing CCTV cameras, and has applications in a number of instances, such as automated tolling, visitor management, car parks, and petrol stations.

Wireless CCTV cameras transmit footage without the need for a coaxial cable, meaning they can be deployed with versatility and the need for only a power cable or other supply. Analogue CCTV cameras have the capability of transmitting up to around 300 feet. They can be equipped with multiple receivers per camera but can be interfered with by household equipment such as cordless phones, routers, or video game controllers, all of which operate on the 2.4GHz frequency. Digital CCTV cameras have the ability to transmit high quality video and audio up to 450 feet, and can be used to trigger, for example, light switches. They can also be integrated with security solutions such as access control.

Infrared Lighting is typically utilised on CCTV cameras in low light conditions. Cameras that can see in complete darkness are equipped with the ability to use infrared, meaning that they can illuminate the surrounding area with wavelengths invisible to the human eye.

IP Cameras

IP CCTV is a modern system that works by transmitting footage as data over a network or internet connection, allowing for greater flexibility in how the cameras are utilised. IP systems can use an existing wired or wireless network, and means that transmitted data can be viewed on a PC, Mac or smartphone. IP systems provide a number of benefits, including:

  • Easy searching of footage logs,
  • High-quality images with none of the degradation that comes from recording over tapes,
  • Being able to both record and play back footage as the same time,
  • Being able to compress data for easy storage.
  • Data can be stored anywhere, reducing data storage costs,
  • Data can be accessed from anywhere
