While most security providers require monthly or yearly maintenance, you can perform self-maintenance checks as well. Aim to check newer security systems every six months and older systems every three months. When performing check-ups, make sure to let your provider know that it's just a test, so emergency personnel are not alerted.
Smoke and fire detectors are required to be inspected annually. You can check your video surveillance camera for the correct date and time as often as you wish.
