Perimeter protection

Smart perimeter protection — a fence that reports itself

Smart perimeter protection replaces the physical sensors nobody maintains with virtual boundaries drawn on the cameras you already own. Mark a line along the compound wall, the yard edge or the roof access, and PGAK raises a real-time alert the moment a person or vehicle crosses it — while filtering out the animals, weather and moving foliage that made your old perimeter alarm unusable.

Sound familiar?

Beam sensors and fence wires fail constantly and cost a fortune to trench in.
The old perimeter alarm fires so often at night that the guard disabled it.
A one-kilometre boundary is covered by one guard at one gate.
You learn about the breach from the damage, not from an alert.

Virtual fencing, drawn in a minute

A perimeter intrusion detection system used to mean buried cable, beam pairs and a maintenance contract. Now it means drawing a line on a camera view. You can change the boundary whenever the site changes, at no cost, on any camera that can see the area.

Line-crossing detection

Alert when an object crosses a boundary — with direction, so entering the site raises an alert and leaving it doesn't.

Zone intrusion

Enclosed areas — a yard, a substation, a roof, a fuel store — alert on any presence rather than on crossing.

Loitering along the boundary

Someone standing at the fence for two minutes is a stronger pre-breach signal than someone walking past it.

Schedules per boundary

The dispatch gate is busy until 8pm and should be silent after; the substation should be alarmed all day. Each boundary has its own hours.

Filtering is what makes it survivable

The reason most perimeter systems end up switched off is not that they miss intruders — it's that they report everything. PGAK classifies before alerting: animals, rain, insects on the lens, headlights sweeping the wall and branches in the wind are suppressed. A boundary alert means a person or a vehicle.

Response, not just notification

A boundary breach can trigger more than a phone buzz — an on-site siren, a strobe, a floodlight, or an announcement. Deterrence during the approach is worth more than evidence after the entry.

Long perimeters, no new cabling

Because it uses cameras that are already installed and powered, extending coverage along a long boundary costs a camera, not a trench. Sites typically start with the two or three most exposed stretches and widen from there.

What to check before deployment

Camera and recorder streams: Confirm RTSP access or ONVIF discovery, stream stability and the views that matter. Do not send camera passwords in the enquiry form.
On-site processing: Ask which processing device is needed, how it is sized, what runs locally and what information leaves the site.
Alert acceptance: Test agreed zones in daytime and at night. Record useful alerts, nuisance alerts, missed events and end-to-end alert delay.
Complete commercial quote: Confirm enabled cameras, sites, subscription, setup, hardware, taxes and support. Use the assessed scope to compare proposals.

smart perimeter protection — common questions

Is this different from AI intruder detection?

It uses the same person and vehicle detection, applied to a long boundary instead of a single area: lines along the compound wall, the yard edge and roof access, with schedules and linked sirens or lights. If you need to know when anyone enters one room or zone after hours, start with intruder detection; if the problem is the length of the boundary, this page is the one.

How is virtual fencing different from beam sensors?

Beams detect that something broke the beam — a bird does that as well as a person. Virtual fencing on camera classifies the object first, so it tells you a person crossed rather than that something did. It also needs no trenching, no power runs along the fence and no field maintenance.

Will wind, rain or animals trigger it?

They're filtered out. Object classification runs before the alerting logic, so weather, foliage and animals are suppressed by default. This is the single biggest reason perimeter systems get abandoned, and it's the part we tune hardest during the first fortnight.

Can it trigger a siren or light, not just my phone?

Yes. Boundary alerts can drive a siren, strobe, floodlight or public announcement at the site, alongside the phone notification. Deterrence during the approach beats evidence after the entry.

How long a perimeter can this cover?

As long as your cameras can see. Coverage is limited by camera placement rather than by the software, and extending it means adding a camera to an existing stretch — not laying new sensor cable.

What a project here involves

Compatible cameras and recorders you already own are reused wherever they are suitable. Detection runs on an on-site processing unit, and camera suitability, stream access, processing hardware and network are all confirmed at the assessment — with anything extra itemised in the quote before you commit.

What the quote is made of

Component	What decides it	Price
Cameras reused	Which existing cameras give a usable view for each use case — confirmed on a still image of each view.	Quoted per site
Cameras moved or added	Only where a use case needs a view no camera has (plates and faces usually do). Each one named in the quote.	Quoted per site
On-site processing unit	Detection runs here, next to the recorder. Model, quantity and warranty depend on camera count and analytics.	Quoted per site
Software / licences	Which analytics on which cameras, the term, and the basis for renewal.	Quoted per site
Installation and configuration	Stream setup, zones, schedules, alert routing and commissioning.	Quoted per site
Pilot	Agreed scenes, acceptance criteria and duration before rollout.	Quoted per site
Support	Hours, response versus fix time, and who replaces failed hardware.	Quoted per site
Taxes	Stated separately on the quote.	Quoted per site

How it is evaluated

1. Self-check — Two minutes, nothing sent — find likely blockers.
2. Scope on paper — Cameras, use cases and acceptance tests, written down.
3. Site assessment — PGAK checks streams, views and network on your cameras.
4. Pilot against criteria — Precision, recall, false alerts and delay, agreed in advance.
5. Written proposal — Itemised as above; you decide whether to roll out.
