Stage 01 of 06
Outside the gate
How do I know about a problem before it reaches my gate?
Before it reaches you
How do I know about a problem before it reaches my gate?
A vehicle turns off the main road, two hundred metres out. Press play on each and watch when the guard finds out.

Cameras only, recordingEverything was captured. Nobody was told. The guard looks up when the vehicle is already at the boom, which is the same moment he would have looked up with no system at all.
Detection, and a route to the guardThe same vehicle, the same road. He knows at two hundred metres and again at sixty, so by the time it reaches the boom he has already looked, already decided, and has forty seconds he did not have before.
This is the whole of this stage. Not whether it was recorded. Whether anybody knew in time to do anything. Every failure below is a different way of losing those forty seconds.
What lives at this stage
Everything outside your boundary line.
- Number plate recognitionVehicle identification on the approach, with whitelist and blacklist reconciliation before the barrier.
- Perimeter detectionFence-mounted, buried or beam-based detection along the boundary, zoned for accurate location.
- First-sight camerasWide coverage of the approach road and standoff area, specified for headlight glare and night use.
- Lighting interlocksExternal lighting tied to the system, so a lighting failure raises an alarm instead of a blind spot.
- Standoff and traffic calmingPhysical layout that slows an approach enough for detection to be useful.
- Escalation to the gateThe path by which what is seen out here reaches the person at the boundary in time to act.
What fails here
Approach systems fail quietly. Nobody notices until footage is requested.
These are the six we find most often on assessment. If two of them sound familiar, the rest are probably true on your site as well.
| What fails | Why it fails | What it costs |
|---|---|---|
| Plates unreadable at night | Camera specified without the dynamic range for headlight glare. | Every ANPR record after dark is useless. The system is running, and the data is worthless. |
| Perimeter detection disabled | False alarms from wind, cats and vegetation, never re-tuned after commissioning. | Someone switched it off in month three. Nobody wrote it down. |
| Water ingress in housings | Seals and glands not rated or not fitted correctly for monsoon. | Progressive fogging. The image degrades slowly enough that nobody reports it. |
| Lighting not interlocked | External lighting on a separate circuit with no monitoring. | A failed lamp becomes a blind spot that raises no alarm at all. |
| No path to the gate | Approach cameras recording, but not routed to the guard's screen. | The system saw it. The person who could have acted did not. |
| Mounting drift | Poles and brackets move with vibration and weather over two or three seasons. | Read accuracy falls year on year. It is treated as a product fault rather than a maintenance one. |
3
Three vendors normally share this stage. None of them owns the gaps between.
The ANPR is one contract, the perimeter detection another, and the external lighting sits with the electrical contractor. Every failure above lives in the space between two of them, which is why it is nobody's to fix.
How we specify it
Six decisions that determine whether this stage works in year seven.
- Plate capture specified for the worst condition, not the averageNight, rain, headlight glare, and the actual approach angle on your site rather than the datasheet's.
- Detection zoned and tuned after handover, not at commissioningFalse alarm rates are re-tuned once the site is live, because a system nobody trusts gets switched off.
- Ingress protection matched to a Mumbai monsoonHousings, glands and drip loops specified for this climate, and inspected as a named line item in the AMC.
- Lighting monitored as part of the security systemA lamp failure raises an alarm rather than creating a silent blind spot.
- Every detection routed to a person who can actEscalation path defined and tested, from the approach to the guard to the command room.
- Alignment recorded at handover and re-verified annuallySo drift is caught as maintenance, not discovered as a fault.
Sector variations
Approach means something different depending on what you are protecting.
Year seven
Everything at this stage lives outdoors. It ages faster than anything else you own.
Sun, monsoon and vibration act on housings, seals, brackets and illuminators continuously. Infrared illuminators dim gradually rather than failing outright, so night performance degrades without a single alarm being raised. Alignment drifts by millimetres a season until plate capture quietly stops working.
None of this shows up on a screen. It shows up when footage is requested and is not there.
What decides whether this stage still works in three years is Maintenance cover and whether anyone has produced a signed condition report since.

A signed condition report naming what works, what has failed, and what was never commissioned.
The assessment is chargeable, quoted against the site, and adjusted in full against the first year if you take cover. Where cover is not taken, the fee covers our team’s time on site and the report we leave behind, and the report is yours either way.
