Picking the right cameras for your system makes a big difference.
Resolution and Image Quality
You need to have a minimum of 1080p, so number plates and faces can be clearly read. Many CCTV systems have been installed with low resolution cameras, which look okay on a monitor, but when you go to identify someone from the footage, the image will deteriorate quickly.
Indoor Versus Outdoor Cameras
Outdoor use: require an IP65 rating and above, whilst indoor use can be of lighter construction. In fact putting an indoor camera outside will drastically shorten its life.
Field of View and Coverage
Wide-angle lens: They cover a larger area but they can also distort the edges. A narrower lens will provide sharper images in the area that you are interested in, like a corridor or entrance way.
Night Vision Capability
Infrared night vision is normally a standard feature on today’s CCTV cameras. However, check the range that it is stated to operate in, for example a camera may be rated for a 10m range in complete darkness, but this does not account for any activity that may occur 15m away.
Wired Versus Wireless
Wired CCTV cameras are the most reliable form of CCTV, especially when it comes to day to day use. Although wireless CCTV cameras are easy to position and install, they do rely on a strong Wi-Fi signal to function correctly. When it comes to CCTV installation in old properties in Worcester, it can often be easier to run cables around the property rather than trying to rely on a wireless signal.
Legal Obligations
Whichever cameras you decide to use, remember that you will have to abide by the rules laid out by the ICO in relation to the use of CCTV and other forms of surveillance. A useful reference for CCTV Worcester is https://apmfireandsecurity.com/cctv-installation/cctv-installation-worcester.
