CCTV System Maintenance
How to keep your CCTV System in good working order

4 Camera color digital video recorder cctv system Maintenance of your CCTV system is vital to ensure the effectiveness of your security camera system. If it has been a while since the last time you looked at your system, chances are there is some dust and dirt that has built up causing cameras to not look their best or your video recorder to work harder than it should. In addition to general clean up, there are DVRs that sit quietly all year and do not get used until there is an incident. If the system is not checked from time to time there is a chance that it may not be recording or a camera has failed.

The worst time to find out that your system is not functioning properly is when you need to pull video and it's not there.

Clean Your Camera Lenses

You may not see how dirty the camera is from the image because its focal point is well beyond the lens. You might be surprised how much clearer your picture will be after a good cleaning.

Check Each Camera

Make sure all cameras are functioning properly. Check both day and night. The camera may work but that does not mean the infrared lighting is. Hint: Use the video recorder's playback feature to check nighttime images without having to wait for nightfall.

Check The Playback On Your DVR

Make sure your DVR (or NVR) is recording on every channel. Don't be caught with a device that is not recording when you need it the most. Make sure the time and date are set up correctly. This will affect any scheduled recording and it's vitally important when using video in any legal matters.

Clean the dusty DVR

Once a year you should give your video recorder a good cleaning. That means top to bottom dusting: inside, out, and underneath. Blow out dust using "Air in a Can" or a similar product from your local office supply store. If your DVR has a removable air filter, take it out and beat the dust out of it. (If you decide to wash it, make sure that the filter is completely dry before you put it back in the DVR!)

Chances are there have been some cameras added, moved, or changed. If so, the cable could probably use a little attention too. Straighten them, label them, and tie them up.

Design It Right The First Time

Experts say that one the biggest problems with security camera systems is that they are not well enough designed to begin with. Many times a business owner is so concerned with cost that they cut corners on their camera installation. As a result there may not be enough cameras used or they might not be the right kind of cameras or lenses. Your camera system should cover all of the vulnerable or important areas of your site. Don't overextend the camera by using lenses with a field of view that is too wide. Test your system to ensure that it's effective for identification - not just verification that someone is there. If nighttime or low light is an issue, make sure your infrared cameras are up to the task.

Conclusion

Take few moments to ensure that your camera system is designed and working properly today - you'll be glad you did if you ever are in the situation to depend on it!
