Unmanned tower sites, watched on the edge, on the backhaul you already have

Nigeria's tower estate is mostly unmanned compounds on diesel and batteries. You already have cameras on a share of those sites. The NOC cannot watch every feed, and the backhaul cannot carry every feed anyway.

Sentinel runs on the site so you get a handful of dispatch-worthy alarms instead of another PIR the night desk ignores. A fuel-level drop with no service vehicle in frame is one of those. A cabinet door open with a person outside the maintenance window is another. A blinded camera is the alarm, not a warning that something might happen next.

The fleet console can see events. It cannot see video unless someone consents to a clip. That is what thin backhaul and a CNII file both actually need.

1. A person at the generator tank, and the fuel level drops

   Diesel leaving a tank is a sensor event. A person at the cap outside a scheduled visit is a camera event. Neither is enough for a high-tier dispatch. Together they are.

2. A cabinet door open, and a person in frame

   A door contact outside a maintenance window is common. A door contact plus a person on camera is a verified breach of a battery or rectifier cabinet.

3. Someone inside the compound with no visit booked

   A person or vehicle on site with no scheduled ticket and no matching service-vehicle telematics is the visible start of a raid on power assets. The page is that presence, not a story about who they are.

4. The fence or the gate after dark

   A person at the fence line, or a gate left open, on an unmanned compound is an intrusion the NOC can act on before the cabinet is open.

5. The camera itself goes dark

   A blinded, moved or covered lens on these sites usually happens minutes before a raid. Treat it as the alarm. Do not wait for the next event.

6. A technician down, or alone at height

   A lone worker motionless on the compound, or at height on the mast with no second person visible, is a safety page on a site that otherwise has nobody there.

7. Fire at the genset or battery

   Smoke or flame at the generator or the battery cabinet is a lost site. The NOC needs the frame and the clock, not a call from the next town.

8. The same plate across several sites

   Repeat presence of a plate or vehicle type across incidents is pattern evidence for a CNII file. It is not a name, and it is not a charge.

Tower sites already have fuel-level sensors, generator run bits, cabinet door contacts, PIR, fence vibration and GPS on service vehicles. Those sensors trip constantly. The camera is how you decide which trips are a drive.

A fuel drop with no scheduled vehicle on camera is high-confidence loss. A door contact plus a person outside the window is a verified breach. Fusion turns thousands of PIR hits into a handful of dispatch-worthy alarms.

A portfolio of unmanned sites cannot stream video to a NOC. It can stream events. Enrol the site, watch on the edge, confirm with the sensor you already fitted, then dispatch only when the drive is worth it.

1. 01 Enrol

   The existing camera, the fuel sensor, the door contact and the maintenance window are attached on site.

2. 02 Watch

   Night-IR models run on the edge, including on compounds with no lamp.

3. 03 Confirm

   Fuel, vibration or a door bit plus a person in frame. Review before dispatch is optional.

4. 04 Dispatch

   The NOC gets an event, not a video stream. A clip moves only if someone consents.

5. 05 Evidence

   Timestamped records with a linked clip stay on the site until you choose otherwise.

6. 06 Fleet view

   The console is events-only across the portfolio. It is not a wall of live video.

Fully edge. Events-only over cellular. A lightweight fleet console for the NOC. Raw video stays on the site. Unlit compounds work with night-IR models. We say so when a site has neither IR nor a lamp.

Do unlit sites work?

Yes, with night-IR models tuned for no lighting and weather. If a site has neither IR nor a lamp, we tell you before you enrol it.

Can you confirm diesel leaving a tank?

The fuel-level sensor sees the drop. The camera confirms who was at the tank. Neither alone is enough for a high-tier dispatch.

What about low bandwidth?

Local inference. Events-only on the backhaul. Clips move only when an operator consents.

Is this evidence for a CNII file?

Timestamped, signed records with linked clips. An accountable person still signs anything that leaves the operator.

What if the camera is blinded?

That is an alert. On this estate it is often the first signal of a raid.

Can a NOC see the whole portfolio?

Yes, through the events-only fleet console. Not through raw video from every site.
