The first thing that comes to mind when talking about CCTV maintenance is how to keep the cameras working properly, especially during the warranty period.
It’s important to keep the cameras working and also clean. See the list below with the maintenance tasks.
Installation
It’s important to examine at each camera to make sure the physical installation is OK. Sometimes some incidents such as hurricanes, earthquakes, wall cracks, or something hitting the camera can affect the camera positioning and integrity.
Field of View
This is also very important. The field of view (FOV) must be checked frequently to guarantee the camera is covering the area it supposed to.
PTZ Presets and Patrolling
If there are PTZ cameras in the system, check if the presets, patrolling and patterns are set according to the initial project.
Cleaning
It’s common practice to clean the dome and lenses at least twice a year..
Condensation
Some dome and bullet cameras can have condensation problems that sometimes are not visible during the inspection, especially if such condensation occurs during nighttime or after raining.
IR Operation
Infrared cameras can have problems with reflection or with the infrared cut filter. Check the recordings to make sure the footage from infrared cameras is good enough and if there’s no IR reflection that hits the camera lens.
Firmware Updates
IP cameras have an operating system that runs different types of services that are frequently updated to maintain software and improve camera security.
The servers and PCs are important parts of the surveillance system. Be sure they are properly maintained. See the recommended tasks below.
- Hardware – Just make sure the hardware is OK. Check the fans, cables, and connectors to make sure they are in working condition, and replace the components if necessary.
- Software – Run a diagnostic tool to make sure the hardware, operating system, and software are working as expected.
- Update – Update the VMS software, drivers, and everything that is necessary to the latest stable version.
- Cleaning – Clean the equipment to remove all dust and insects that like to live in electronic devices.
- Power – Check the power and make sure the UPS system is OK.
