How often should a home alarm system be professionally serviced?

Most security system manufacturers recommend annual servicing. Backup batteries typically need replacement every 3–5 years. If your system is older than 10 years, discuss an upgrade with a licensed security technician — older systems may not be able to communicate with modern monitoring centres.

Do wireless alarm sensors need battery replacement?

Yes — wireless sensors (door/window contacts, PIRs) typically run on lithium batteries lasting 2–5 years depending on usage. Most panels will notify you of low battery, but periodic manual checks are prudent if you haven't received a notification in years.

What should CCTV storage I need for a Melbourne home?

For effective evidentiary footage, most security professionals recommend minimum 4 weeks of continuous recording at a resolution of 1080p or higher. Check your NVR or cloud storage settings — many default to lower quality or shorter retention to save storage space.

Home Alarm & CCTV Maintenance Checklist for Melbourne Homes

A security alarm or CCTV system that malfunctions when you need it provides no protection — yet many systems in Melbourne homes have dead batteries, offline cameras, or disconnected monitoring without the homeowner being aware. This checklist covers the four self-observations that verify your electronic security is actually functioning as intended.

Self-Check Checklist

1 Test your alarm system by triggering a sensor (with your monitoring company advised) — verify the siren sounds, the keypad responds normally, and you receive a call from your monitoring centre if applicable.
2 Check alarm panel battery backup: most panels have a battery warning light or display. If the battery warning is active, the system will not operate during a power outage — which is when intruders most often strike.
3 Review your CCTV camera coverage from the recorder or app: verify all cameras show a live image, that night vision is functioning in low-light conditions, and that your storage (NVR or cloud) is recording as expected.
4 Walk your property and check all detection devices — passive infrared (PIR) sensors, door/window reed switches — looking for tampered, damaged, or physically displaced devices that may have lost their protective coverage area.

Warning Signs to Look For

⚠ Alarm keypad showing 'Low Battery', 'Fault', or 'Tamper' warnings
⚠ Cameras showing offline, no image, or incorrect timestamp
⚠ Monitoring company not calling during a test alarm
⚠ PIR sensors with dirty lenses or that have been physically moved
⚠ CCTV footage with gaps, corrupted video, or insufficient storage
⚠ Alarm not sounding during self-test or requiring multiple tries to arm

Cost of ignoring

An alarm system with a flat backup battery provides zero protection during power outages — exactly when sophisticated intruders operate. CCTV footage that fails to capture an incident has no evidentiary value. Annual electronic security maintenance by a licensed security technician costs $150–$300 and ensures the system performs when you need it.
