AI weapon detection camera

A weapon visible at an entrance is a situation where minutes matter, and where reviewing footage afterwards is no help at all. Weapon detection analytics watch for the visual signature of a weapon held in view and raise an alert so a person can look and decide. The judgement stays human; the software only shortens the time before someone is looking.

How it works

Specialist analytics look for the visual signature of a weapon held in view and raise an alert for a person to judge.

Where it could help your business

Give a reception desk a faster route to a decision than noticing it themselves.

Treat this as an alerting aid attached to a response plan, not a safeguard on its own. Agree who receives the alert, what they check and what they do next, before it is switched on. Test it in your own lighting and camera angles: a tool held at waist height in a crowded frame is a much harder case than a clear demonstration, and you should see both before you buy.

What your camera setup needs

Every alert needs human review before anyone acts. Concealed items cannot be detected, and this is not a screening or scanning system.

Can it detect a concealed weapon?

No. Video analytics can only work with what the camera can see, so something inside a bag or under clothing is not detectable. This is not a screening or scanning system and should never be described to staff as one.

Check it on your own site

Bring a camera model list and explain the event you want to find or detect. We can use that to scope a compatibility assessment. Ask for a written proposal naming the supported functions, processing hardware, licences and pilot checks before agreeing to an installation.

Weapon detection: estimate it for your site

Use your own measurements. The result is the staff time released, shown separately from any cash, using the formula below. It runs in your browser and nothing is sent anywhere.

Fields start empty. A blank is “not entered”, not zero; type 0 where 0 is true.

Money (optional)

Salary plus benefits and overheads, per working hour. Needed only if you enter a realisation above 0%.

0% unless you can name the mechanism — overtime that stops, a post not refilled, a contract reduced.

Only from your own records. May be negative.

Licences, support, connectivity. Enter 0 if there is none.

Hardware, installation, commissioning. Enter 0 if there is none.

Enter every amount on the same basis — all including GST or all excluding it. Nothing here adds or removes tax. Values are nominal rupees, not discounted.

Result

Enter your own figures, or load the worked example, to see the result.

How it is calculated

hours = alerts × (manual − assisted) ÷ 60 − escalation hours

Worked example (illustrative inputs)

40 alerts; 6 old; 2 new; 1 escalation hour.

staff time released: 1.667 hours a month.

Formula version 1.0.0.

What this does not tell you

  • Hours released are capacity, not cash. They become cash only through a mechanism you state — overtime that stops, a post that is not refilled — entered as the realisation fraction.
  • The 'after' values are your assumptions or pilot measurements. PGAK publishes no effectiveness figure for this feature.
  • This estimates review effort only. It does not value injuries or lives, does not promise that any incident is prevented, and is not a replacement for certified alarms, required guards or supervision.

Evidence status: Supplier/integration or marketed capability; PGAK availability and site performance require verification.
