CCTV Company in London
Our CCTV installers in London & Kent, offer a comprehensive expect service ranging from a single camera monitoring one point of entry through to a sophisticated package that monitors every access point (including at walls and fences) and even multiple locations and buildings. All of our CCTV systems can integrate with Access Control and Automatic Number Plate Recognition systems.
And if you need multi-site access control from a single central monitoring station controlling CCTV, gates, doors and barriers, we can link them all together.
Our CCTV contractors are able to access your current Perimeter Intruder Protection and advise on aspects such as anti-climb walls and fences and other impediments. We will also advise on Security Lighting either to compliment your CCTV camera or as a standalone deterrent.
Modern CCTV systems have come a long way and now feature full colour, high-resolution rendering which work almost as well at night as they do in the day.
CCTV is an area where our company particularly excels as they can be integrated with all our security systems and can be linked to remote monitoring stations – even overseas if you require. These days, CCTV does not even need to be hardwired, wireless CCTV installations are proving increasingly popular. Not only can it work over Wi-Fi, it can be effective over a 4G Mobile Network. ACCL are also experts at connectivity via laser or microwave over relatively short distances.
CCTV Camera Installation
CCTV camera installations have a variety of uses. In the field of Internal and External Access Control it can be deployed so that if a door is unlocked, a camera will be activated in that location. If the camera is already active, it can be set to run at a higher frame rate and quality of resolution. Both working room lights and security lighting can be turned on.
Should there be a perceived emergency situation, CCTV can be put to good use to verify what is happening and advise of the extent of an actual fire or intrusion for example.
When positioned at the perimeter of a site, CCTV systems can monitor walls and fences and other intruder hotspots. One of the best ways to get a return on investment is to use CCTV to grant entry via Pedestrian Gates or via Vehicular Gates, Barrier and Bollards. It can be linked to all Access Control Mechanisms such as card readers and can also incorporate Facial Recognition to provide automatic entry or an additional layer of verification.
There is a vast range of CCTV system hardware from the simple camera on an intercom, through to internal multi-direction dome cameras through to external models that can zoom in and out over long distances and operate in low light conditions. Our CCTV installers are familiar with all the major camera and systems suppliers and will design and install a solution that suits your current needs and can grow to meet your future needs. If you want a fully integrated, computer controlled system with multiple facets or a simple intercom, we will advise you accordingly.
Wired vs Wireless CCTV Systems
Wired CCTV systems are the most common and cheapest type of camera, where a wire plugs directly or indirectly from the camera to the monitor. The downside is that not being wireless the wires, including extension cables and connectors, are easier to locate and disable.
Wireless CCTV systems are more “the norm”, these days as they use the power of the Internet to transmit images back to a central resource and for smaller or domestic installations can be linked to an App and thus viewed over a mobile phone.
Wired & Wireless CCTV Integrity
The wireless aspect from camera to base-station can suffer from ‘chatter’ and can be blocked by metal in structures and thick walls. ACCL’s advanced systems and networking capabilities ensure this will not happen.
Any IP-enabled device is open to hacking whether it is wired or wireless. ACCL’s solutions all include the latest in encryption protection.
CCTV Camera Image Quality
Our CCTV installers recommend the use of high-resolution cameras (with up to 30 megapixel CCDs using CMOS chipsets). The efficiency of a camera is judged by the size and type of chip it uses. CCTV cameras with smaller chips tend to be able to pick up less light, and therefore produce lower quality images. The light sensitively is measured in Lux, which can range from 130,000 to 0.001 – the lower the Lux the better the camera will record . High-quality images – sufficiently clear for someone to be identified – are needed if CCTV footage is to be used as evidence in court. For the best detail, high resolution is required. High resolution means large files and slower transmission to an end storage facility. ACCL’s network abilities come to the fore in advising on such aspects.
Extending the life of legacy systems
As your installer we recognise that it is not always possible to fund an entire replacement of CCTV hardware and infrastructure. We are able to advise on the latest encoding software that will allow the upgrading of analogue cameras and the migration to Internet transmission. In conjunction with changing recording devices, ACCL can help enhance the quality of your existing system, allowing it to be overhauled in a controlled timescale.
As with all ACCL’s services, we can integrate a variety of systems. Our guarantee is our consultation and design services are based on achieving our customers aims both in the short and long term.
The ACCL security team are also certified installers of Avigilon CCTV products.
