Natural language video search

You know what you are looking for, but not when it happened. Natural language video search lets you describe a person, vehicle or object and review matching recordings. A warehouse manager might search for a white van near the gate instead of opening every camera and guessing the time.

How it works

Describe the person, vehicle or object you need. Find relevant footage without scrubbing through hours of recordings.

Where it could help your business

Search a Delhi site for a white vehicle arriving after closing time.

Start with simple descriptions from your own footage. Try clothing colour, vehicle type and location separately before combining them. Keep the original clips available so an operator can check each result; a convincing match can still be the wrong person or vehicle.

What your camera setup needs

Requires a compatible search platform or AI recorder. Query support and indexing capacity vary.

Can I search all my old CCTV recordings?

Only if the proposed platform can ingest and index those recordings. Ask which cameras, recording formats, retention periods and historical imports are supported before assuming your archive is searchable.

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.

Natural-language footage search: 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.

Checking each suggested clip against the original recording.

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 = cases × (manual − assisted − review) ÷ 60

Worked example (illustrative inputs)

20 cases; 90 manual; 15 assisted; 5 review.

staff time released: 23.333 hours a month.

Formula version 1.0.0. The full standalone tool: investigation time.

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.

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

Request a site-specific assessment with these assumptions

Your result stays on this page either way. If you want it checked against your cameras and quotation, leave a number; mention the figures on the call. Nothing you typed into the calculator is sent with this form.
