Perimeter Security

Watch kilometres of fence with thermal cameras, AI, fence sensors and lighting, for mines, plants and substations.

Perimeter Security

What we usually find on site

Mines, solar farms and substations have kilometres of fence that guards can't patrol fully. Copper cable, fuel and equipment theft tends to happen at night, at the point furthest from the guard house.

A secure perimeter is built in layers: deter → detect → verify → respond. Miss one and there's a gap.

Fast, accurate detection

  • Thermal cameras see people and vehicles in darkness, fog and smoke at far longer range than visible cameras. They're for detection, not identifying who it is.
  • AI analytics catch line crossing and zone entry and filter out animals and moving vegetation.
  • Fence sensors (vibration or fiber-optic) know when someone climbs or cuts the fence and which zone it's in.
  • Radar covers open ground with no fence.

Verify and respond

On an alarm, a PTZ camera swings to the spot on its own (slew-to-cue), floodlights come on and a speaker issues a warning. Most people leave when a voice announces "we can see you". At the same time, video goes to the control room and the guards' phones.

Infrastructure that survives the site

Poles far from grid power run on solar + battery and connect by PtMP radio or fiber. Batteries are sized for several overcast rainy-season days in a row, not one. Every pole is earthed with surge protection. And keep the fence line cut back: tall wet-season grass makes life much harder for AI and thermal cameras alike.

What it does

Thermal detection

People and vehicles in total darkness and fog.

AI false-alarm filtering

Separates people and vehicles from animals and trees.

Fence sensors

Detects climbing and cutting, by zone.

PTZ slew-to-cue

The PTZ swings to the event on its own.

Lights and talk-down

Sends intruders away before damage is done.

Solar and wireless poles

For spots with no power or cabling.

Design and rollout

  1. 1

    Assess risk; walk the fence line, terrain and vegetation

  2. 2

    Design detection layers: thermal, AI, fence sensors or radar

  3. 3

    Plan poles, power (grid or solar) and network (fiber or radio)

  4. 4

    Install with earthing and surge protection

  5. 5

    Connect VMS, set slew-to-cue and write guard procedures

  6. 6

    Run staged intrusion tests by day and by night

FAQ

Can thermal cameras identify faces?

No. Thermal is for long-range detection. To see who it is, you need a PTZ or visible camera with lighting working alongside.

Will animals and trees cause false alarms?

AI and on-site tuning cut them a lot. But what helps most is often just keeping grass and branches trimmed along the fence.

What about spots with no power?

Yes, with solar poles and batteries sized to the load and to several overcast days in a row in the rainy season. Tell us how long the fence is and where power is available, and we'll plan the poles.
