CCTV Cameras

The two main considerations for anyone looking to invest in CCTV are the cameras and the system itself. Here we explain the options:

Types of CCTV Cameras

IR cameras – These cameras are particularly useful for outdoor surveillance. This is because they use infra-red to record, allowing them to record in all light levels, including in areas where there is no light.

Dome cameras – These cameras offer a much more discreet method of surveillance, and are often used by small business owners for indoor monitoring. The domes in which the camera is concealed disguise the direction in which the camera is pointing, meaning it is much more difficult to evade these cameras.

Pan-tilt-zoom (PTZ)?- These cameras are often contained in the same casing as dome cameras. The benefit of these cameras it that they can, as the names suggests, pan, tilt and zoom, to track their subject across the room. This, of course, means that any intruder can be recorded for a longer period of time.

CCTV Systems

DVR – Analogue cameras linked to a DVR (digital video recorder) can typically store the images that they record for 30 days before they are overwritten. DVRs record the images your cameras capture and provide a reliable alternative to recording footage on a computer, which may crash if relied upon for continuous 24 hour recording.

IP – IP (internet protocol) camera systems are digital system often considered to be more appropriate in larger premises where the increased use of coaxical cable required to expand an analogue system would increase costs. IP systems can also utilise megapixel cameras which can capture images of a much higher quality. Therefore, they can offer higher performance when it comes to the identification of an intruder. These systems transfer their data through an ethernet cable and, as such, can provide their user with remote monitoring capabilities.
