A CCTV camera or Closed Circuit Television camera is simply a camera device that connects back to a central control box for displaying it's video output. Most cameras provide colour video during daytime and black and white video at night using infra red light. The camera is powered by a power cable from the control box and the video transmitted via a coaxial cable. The term closed circuit is the connection of the cabling back to the control box.

Please look at this tutorial on youtube,

The old systems is not difficult to do it yourself if your technical minded, although the newer systems will require some IT background. I recommend a certified installer to assist you, you can damage the camera if you don't know what your are doing.

Get the correct cabling and connectors.
The easiest are the pre-crimped cabling for DIY and it is plug and play. No setup is usually required for the CCTV recorder to work unless the recording on the CCTV was disabled. Any other setup will require special tools.

You get 2 kinds to wired CCTV camera systems.

I have a sentient cctv dvr from Maplin I can view it on my phone at home which is fine I wanted to know if I can view camera footage when I'm not at home etc. at work


Yes you can definitely view your CCTV footage on your mobile phone at your work via internet. Sentient CCTV DVR basically is a night vision camera. You must know the IP of the camera and IP Video server. Connecting your phone to CCTV camera via the protocol you can view the CCTV footage's in your phone. Night vision cameras are used for surveillance purpose. I would prefer cctv camera with ir illuminator for good image quality in the night time that will clear footage quality in my phone.
Recently many new applications have also being launched by security cameras with a view to solve problem you mentioned.

I think I answer you question--when?? Take the good CCTV camera and hook it up to monitor. Then hook up the CCTV camera and turn it on. Point the working CCTV camera at the bad camera that is turn on. Now, look at the monitor which is working with your operational camera. Look at the bad camera while it on, and see how many IR LED's you can see on the bad CCTV, while it turn on. You should be able to the IR LED glowing red. If not, then there is a problem with bad CCTV IR LED's. Short wire, no power to the IR LED's. stewbison
