Everything You Need to Know About CCTV Maintenance

Having CCTV systems installed at your property is a great way to keep it safe and secure. But, it’s important that they’re well maintained in order to ensure that they’re working as they should be.  

As well as acting as a deterrent, CCTV systems will help identify and catch intruders and thieves should they successfully or unsuccessfully attempt to break into your property. 

At A.T. Alarms, we provide a wide range of CCTV options to domestic and commercial properties across the UK, including Nottingham. 

Our team of expert technicians have put together a comprehensive CCTV maintenance guide, outlining everything you need to consider when it comes to keeping your security cameras working at their best.

CCTV maintenance checklist

The entire point of having CCTV systems installed is to keep your property safe. Whether it’s your home or business, if the cameras are not working correctly then, in the event a break-in does occur, you’re going to be unprotected.

There are a few checks you should regularly carry out to ensure your CCTV is performing at its best. These include: 

Camera lens

Make sure your camera’s lens doesn’t have anything obstructing it. Is it clean of any dust, debris or marks and is it focused on the area of your property you want it to view? If any trees, plants or foliage have become overgrown since the CCTV was installed, it’s also worthwhile checking that the lens isn’t obscured by it, trimming the relevant greenery if necessary. Also, make sure the camera itself is firmly attached and hasn’t been knocked off its course. Readjust it if this is the case to ensure it’s covering your whole perimeter.


Make sure that any wires relating to your CCTV cameras and accompanying components are in a good condition and not suffering from any wear and tear. Loose, exposed or frayed wires may need replacing as they can cause your system to not function properly. If this is the case, contact a professional security services company that will be able to replace them for you.

Monitors and control systems

Even if your cameras are in good working order, if the control panel is not then you may not be able to view the images. Make sure the image on your monitor is clear and the brightness and contrast settings are working correctly. Check all wires and cables are properly connected and in a good condition. It’s also worthwhile to give the control panel a general dusting to remove the buildup of grime or dirt. You should also check that the time and date stamps on the screen are correct. 

Areas to focus on

When carrying out maintenance, it’s a good time to make sure that all the key areas of your premises are fully covered. There are a number of places that CCTV systems should cover. These include:

  • Entrance and exits – to cover all comings and goings
  • Reception areas – due to the high foot traffic likely to pass through these areas
  • Car parks – to keep vehicles safe
  • Corridors – to monitor people’s movements within buildings
