CCTV maintenance and AMC in Sri Lanka: what to ask before you sign

Maintenance is a different service from installation

Installation delivers a working system on a given day. Maintenance keeps it able to produce usable footage months and years later, when a camera has drifted, a disk has failed quietly or a lens has clouded over.

Treating them as one purchase is why so many systems are found to be recording nothing on the day footage is finally needed. An agreement should describe the ongoing work explicitly, separately from any installation scope.

Ask exactly which assets are covered

The covered asset list is the foundation of the contract. It should name cameras by position, the recorders, storage, power supplies, network equipment in the CCTV path and any monitors or client software in use.

Where a site has grown over time with mixed equipment, say so before pricing: an unlisted camera is an uncovered camera when it fails.

• Camera schedule by location and type
• Recorders, storage and any archive arrangement
• Power supplies, PoE switches and cabling in scope
• Viewing clients, monitors and remote access setup

Preventive visits and what happens on them

A preventive schedule only means something if the visit content is defined. Ask what is inspected, cleaned, tested and recorded each time, and whether the visit produces a written report.

Physical work matters as much as software checks — housings, seals, mountings, cable entries and glass all degrade in Sri Lankan weather and are easy to inspect and easy to ignore.

Recording verification, not just live view

A camera showing a live picture on a monitor may not be recording. Verification means confirming that each camera is writing to storage, that the recording covers the hours it should, and that footage can actually be exported.

Ask for a test export as part of the routine. It is the only check that proves the whole chain works end to end.

Storage, retention and disk health

Retention drifts. Cameras get added, resolution or frame rate changes, motion settings are adjusted, and the number of days actually held falls without anyone noticing.

The agreement should include measuring real retention against the retention you require, and checking disk health so failures are caught before footage is lost rather than after.

• Days of footage actually retained, measured not assumed
• Disk health and any recorder warnings reviewed
• Effect of any new cameras on existing retention

Image quality, focus and camera positions

Cameras move. Vibration, cleaning staff, weather and building work shift views, and a camera pointing slightly differently may no longer cover the area it was installed for.

Comparing each view against a reference image from handover is a simple check that keeps coverage honest, alongside focus, exposure and night performance.

Time synchronisation

Footage with the wrong time is far less useful, and inconsistent clocks across recorders make comparing sites or incidents difficult.

Ask for time synchronisation to be checked and corrected at every visit. It takes moments and it protects the value of everything recorded between visits.

Network health and remote access

Most modern CCTV depends on switching, Power over Ethernet and, where required, a route in from outside. Errors on links, PoE issues or an intermittent connection show up as unreliable cameras long before anything fails outright.

Remote viewing can be configured where required, subject to the site internet and network arrangements, and any remote access in place should be reviewed as part of maintenance rather than left untouched for years.

Fault reporting, diagnosis and escalation

Agree how faults are reported, what information helps, how a fault is diagnosed and what happens when a part is needed. Clarity here matters more than adjectives about responsiveness.

Also agree what is excluded — accidental damage, lightning, theft, building works, third-party changes and equipment beyond economic repair are the usual candidates. Exclusions written down before signing prevent arguments later.

• How to report a fault and what to include
• Diagnosis approach: remote first, then on site
• Parts and replacement handling
• Written exclusions and anything chargeable outside scope

Documentation and lifecycle advice

Good maintenance leaves a record: what was checked, what was found, what was corrected and what needs attention next. Over a year that record tells you where the system is heading.

It should also inform replacement planning, so ageing recorders and cameras are budgeted for rather than replaced in a hurry after a failure.

Questions worth asking every bidder

Ask each provider for the covered asset list, the visit checklist, the retention verification method, the reporting format, the escalation path and the exclusions. If two proposals differ in price, these answers usually explain why.

We are happy to answer all of the above in writing for a defined site, and to survey an existing system before proposing a scope.
