The frequency of CCTV backup depends on the nature of the business or premises being monitored. For example, if you own a retail store, it is may be necessary to back up your CCTV footage weekly or monthly to ensure that any incidents that occur in the store are captured on camera. In contrast, if you own a home, backing up the footage everytime an interesting event happens.

It is important to ensure that your storage system has a large enough capacity to allow sufficient time to pass before the data overwrites on the hard drive

It is important to note when the CCTV is beeping – as this can sometimes mean a hard drive failure and it has stopped recording at that point.
