If you’re having some problems with your CCTV, don’t worry! There are some things you can do to get things back up and running. Most issues come down to things like power or poor placement, so a few quick checks can usually get things back on track. Here are some common CCTV problems and how to fix them.

Flickering or lines

Flicker and lines could be interference, so play around with camera cable placement – keep them away from mains power and check shielding and grounding.

Mobile viewing not working

If live view’s not working on your phone, it’s probably an issue with the settings on your app or cloud. For recording failures, have a little look at your storage space.

And check if your motion settings are not too strict.

Poor night vision

If night images don’t look quite right, give the lens a clean and check for things like spider webs or rain spots and angle cameras away from street lights or reflective surfaces. Also confirm the camera is actually switching into night mode and has enough power.

No video signal

Start with the basics if there’s no picture. Is the camera properly powered? Check the cable for damage and try a different port on the recorder. If it’s a recurring headache, local companies who specialise in CCTV installation Swindon, for example, like //apmfireandsecurity.com/cctv-installation/cctv-installation-swindon/ can help get to the bottom of any problems.

Most CCTV faults are fixable at home, though. Once you get the basics sorted, your system should run quietly in the background.If you’re having some problems with your CCTV, don’t worry!
