Choosing the right kit
Security systems get noticed the moment they stop working properly, but the maintenance that keeps them working rarely gets a second thought until an alarm fails to arm or a camera turns out to have been recording nothing for weeks. For a small business, that gap can matter far more than for a home, since insurers, landlords and sometimes clients expect evidence that systems protecting stock, premises or staff are actually looked after on a regular basis.
Most burglar alarms benefit from a service at least once a year, with some higher risk or heavily used commercial sites suited to a six monthly check instead. CCTV systems have their own separate lifecycle concerns, particularly around hard drive health and lens or housing condition, that do not always line up neatly with an alarm's service schedule. Treating the two as completely separate maintenance items, rather than assuming one visit covers everything, avoids nasty surprises with either system.
Servicing is not simply a box ticking exercise either. A proper visit checks battery condition, tests sensors and sounders, reviews recorded footage quality, and produces a record that can be shown to an insurer if a claim ever needs supporting. For a business that relies on its security system daily, a small annual or six monthly cost is generally far cheaper than discovering a fault only after something has gone wrong.
Assess Your Own Setup First
Check when your alarm was last professionally serviced
Look for a service sticker inside the panel or a previous invoice. If it has been more than 12 months, or you cannot find any record at all, it is worth booking a check regardless of whether anything seems wrong.
Review CCTV footage from several weeks back
Pull up a recording from a few weeks earlier to confirm the hard drive is genuinely overwriting and storing footage correctly, rather than assuming it is working simply because the live view looks fine.
Note any battery replacement dates you have on file
12V sealed lead acid batteries in alarm panels typically need replacing every few years, and keypad or sensor batteries have their own separate lifespan, so keeping simple dated notes helps plan ahead rather than reacting to a fault.
Ask what a service visit actually includes
A proper service should cover battery testing, sensor and sounder function checks, tamper loop testing, and for CCTV, checking recording quality, lens condition and hard drive health, not just a quick visual look.
Keep service records together in one place
Store service certificates, invoices and any fault reports together so they can be produced quickly if an insurer or landlord asks for evidence of regular maintenance after an incident or claim.
Flag any near misses to your engineer
If the alarm has recently given a false trigger, a tamper fault or the CCTV has had an unexplained gap in recording, mention it before the next service so the engineer can specifically investigate that history.

How Often Should Your Business Alarm and CCTV Be Serviced: common questions
What Each Approach Handles Well
Annual servicing as the general baseline
Most commercial burglar alarms are serviced once a year as standard practice, which is generally enough to catch battery degradation, sensor drift and minor faults before they cause a false alarm or a failure to arm.
Six monthly servicing for higher risk sites
Sites with higher footfall, valuable stock, or systems that are armed and disarmed frequently throughout the day can benefit from a six monthly check, since more frequent use tends to wear components and batteries faster.
Battery lifecycle and gradual failure
12V sealed lead acid batteries typically last a few years before capacity drops noticeably, and this decline is often gradual rather than sudden, meaning a battery can be quietly underperforming for months before it fully fails.
Hard drive health and overwrite cycles
CCTV recorders write and overwrite footage constantly, and hard drives have a finite lifespan measured in these write cycles, so a drive that has never been checked can develop bad sectors that silently corrupt recent footage.
Insurance and record keeping requirements
Some commercial insurance policies expect evidence of regular maintenance for security systems, and without dated service records a claim following a break in or theft can become more complicated to support.

Getting it right first time
Book alarm and CCTV servicing as two separate, planned annual or six monthly appointments rather than waiting for a fault, and keep every service record filed together so it is ready the moment an insurer or landlord asks for it.
