CCTV System Installation
CCTV Systems: What are your options?
As part of our services we install, monitor and maintain CCTV (closed-circuit television). CCTV is a proven vital element of security and helps a business to protect its people, assets and property.
Our highly experienced engineers are expertly trained in all aspects of installing and commissioning CCTV systems. Additionally we provide support and advice to meet all customer requirements, and pride ourselves on unrivalled customer care and after-sales support.
We are an SSAIB accredited installer, and are bound by guidelines set out by the SSAIB Governing Board for install, documentation and commissioning.
ANALOGUE & IP CCTV SYSTEMS:
Whilst both analogue and IP systems are categorised as providing exactly the same end result, both are different in many aspects of install and site requirements.
Our experienced engineers survey your site free of charge, discuss your needs and expectations and how you could benefit from having a CCTV system or whether you just require a digital recorder upgrade.
The experience we have built up over recent years with both IP and Analogue systems allows us to satisfy all of our customers’ needs from simple four-camera systems up to 100+ camera systems.
ANALOGUE CCTV SYSTEMS:
Digital Video Recorder (DVR) will be the device in which all images and sounds, if required, are recorded on. We use minimum of a terabyte hard drive, even just for a four channel unit.
DVRs are traditionally supplied as four, eight or 16 channel units – 16 channels allowing 16 camera inputs. The whole system comprises of a physical direct connection of either coax or Cat 5 cable and the system will be completely standalone.
Images are analogue in appearance, rather like a home television before HD was introduced. Images cannot be enhanced during playback or whilst viewing recorded footage. Analogue systems can record in full real time at 25FPS (frames per second). Humans can see only 15FPS.
IP CCTV SYSTEMS:
Network Video Recorder, more commonly known in the industry as a NVR will be the device in which all images and sound (if required) are recorded on. IP systems use mega pixel or HD 1080P cameras. This type of camera can be likened to your TV HD pictures and provide unrivalled quality against analogue systems.
Mega pixel (MP) images can be enhanced during playback or whilst viewing recorded footage. Higher hard drive capacities are required as the NVR will be recording in a higher resolution although real time can still be achieved with the correct set-up and system management.
The whole IP system uses structured cabling Cat 5 or 6 and in most cases a site will require a complete separate network to that which will be used for staff PCs. A considerable load, even for a couple of cameras will cause problems on a basic network if not set up correctly.
