CCTV Terminology

If you run a business that has its own premises then making sure that you have some form of CCTV in place is a necessity. This will help you in many ways to protect your business from theft or vandalism acting as both a deterrent and as an early warning system and a way of aiding the police in their investigation and providing evidence in court. If you have CCTV in your building them you can prevent the majority of criminals from trying to break in, catch the majority that do red handed and track down any in the slight chance that they get through.

However going about installing CCTV can be quite tricky for those new to the subject when so few people understand all of the different terminology and jargon surrounding the subject. There are a vast range of different CCTV systems and knowing which is which and what you need to look out for can be complicated. To make matters a little easier, here is a guide to just some of the terms.

CCTV: CCTV itself stands for ‘Closed Circuit Television’ – in other words it means that you have video footage that is not designed to be broadcast but that remains within the ‘closed circuit’ of your building. Today that circuit is more a metaphor as some footage is now streamed.

Analogue CCTV: Analogue is the opposite to digital – in other words it doesn’t use a computer or programming or electrical signals in the same way that say digital TV or digital radio does. This is an outmoded form of CCTV that only has limited uses today.

Digital CCTV: This is more like it – this is what most modern and serious organizations will use in order to protect their company and it creates data that can be saved on a computer or memory card or which can be streamed live.

IP CCTV: IP CCTV stands for ‘internet protocol’. It means that the footage is sent wirelessly to be picked up by another computer or saved at a remote server. This also means that you have no wires for your IP CCTV and that means that you are less restricted with where you can place your cameras and you will be able to move the cameras with ease when necessary (due to a redecoration for instance).

Wireless CCTV: Wireless CCTV is any form of CCTV that has no wires – such as IP CCTV.

VoIP CCTV: This stands for ‘Voice IP CCTV’ and essentially means that you have a camera that doesn’t only film footage but also sound. That then means that you can listen to what is happening on your premises, and it means that you can broadcast your own voice to ask people on-site for status reports etc.

Video Analysis: Video analysis means that your footage can be analyzed by a computer in order to look out for things that are out of the ordinary or alarming. For instance video analysis might sound an alarm if it sees movement that appears human in nature.
