How often should an alarm or CCTV system be serviced?

Servicing keeps the system useful, not just switched on

An alarm or CCTV system can appear to be working while batteries, camera views, recording health or remote access are beginning to deteriorate. Planned servicing gives an engineer the opportunity to test the system properly rather than waiting for a fault to become obvious.

The right service frequency depends on the system, property and any specific insurer, manufacturer or site requirements. For many customers, an annual engineer visit provides a sensible starting point.

What a professional service may include

The exact scope should be confirmed in the quotation or service agreement.

• Device and communication testing
• Battery and power-supply checks
• Sensor and camera cleaning
• Recorder and hard-drive health checks
• Playback and remote-viewing tests
• Firmware and system-status review
• Service records and identified defects

Aftercare should be clear from the beginning

NOX introduces monitoring, maintenance and takeover support after the installation scope is understood. Customers can choose the level of aftercare that makes sense without being forced into an unnecessary package.

Existing systems can also be inspected before a maintenance plan is agreed, particularly where access details, faults or equipment history are unclear.
