In case of failure or breakdown, change the batteries of the main unit and wireless sensors, according to the manufacturer's recommendations. If you use external monitoring, make sure the Alarm Receiving Center (ARC) receives the signals correctly.

Surveillance cameras (CCTV)

Regularly clean camera lenses to prevent any specks of dust or dirt from affecting image quality. Also check the camera angle to make sure they are covering the correct areas and make adjustments if necessary.

Furthermore, we recommend inspect cables and connections, especially if the cameras are installed outdoors, since they will be much more exposed to climate changes and this could affect their operation.

Also don't forget to check the storage space on your DVR or NVR, if images are stored locally, and make regular backups.

Motion sensors

Clean the sensors to prevent dust or dirt from affecting their sensing ability. If required, test the sensor frequently to make sure it detects motion in the right area.

Smoke and carbon monoxide detectors

Test the detectors at least once a month to ensure that they emit signals correctly alarm. As for the batteries, we advise you to change them at least once a year, or do so if the system alerts you with a beep.

Like motion sensors, clean the openings of the smoke and carbon monoxide detector to prevent the accumulation of dust that may interfere with its operation. You may also need to change detectors every 10 years , although this will depend on the manufacturer's recommendations.

Outdoor security lighting

Regularly check the light bulbs to make sure all of them are working and replace them when necessary. While you're at it, also clean the light covers to ensure they emit maximum brightness.

Also don't forget to check the motion sensors connected to the lights to make sure they activate correctly when someone approaches. Given the outside conditions that any outdoor security device faces, also make sure the wiring is well protected from the weather.

Smart locks

Update the smart lock firmware regularly to maintain optimal security and functionality. Another tip for taking care of the locks, if they have any physical component, is to lubricate those parts well, at least once every six months or annually, to avoid jams.

Fire detection systems
