We all like music but not of every kind and definitely not a beeping, grinding or buzzing sound coming from the CCTV Camera DVRs / NVRs.

An electronic surveillance device can make sound in two cases , one ,  it is made or set to do so and second in particular scenario and hence want to pass some information , in second case it is just a malfunction.

To pass on the information: This may be of some snag in device itself so that we can attend to it or a surveillance information i.e. motion sensing, camera nearness sensor, line cross sensor etc.

Because of Some Malfunction: Sound Coming due to the damaged hard disc, damaged fan etc.

Now with the type of sound also we can get an idea what may be the reason behind it .

Noise and beeping origin may vary depending on what you are hearing. Beeps are usually related to firmware mis-configuration or for giving some information  and other noises are more connected to hardware issues. We will talk about beeping first and then will go to other issues.
