In addition, it’s a closed circuit network of cameras. So each camera at their own position will have varying timeframes for recording.

Most often it’s 24/7 with monitoring from security. However there are two types, on site and off site monitoring and recording.

Onsite is seen most often with smaller companies. Mom and pop shops, however larger companies have it as well.

Off site monitoring can be done by larger companies that outsource the work for multiple reasons. Possibly insurance claims if there is any claims like damage from weather, people, animals etc, or thefts. There is a separate eye witness for legal reasons and the equipment is installed and maintained by that company. Like ADT, or even Brinks security. But most importantly the video feed can be left with the company off site safe and secure to an extent.
