AI face privacy masking CCTV

You may need to understand activity without showing every person’s face to every viewer. AI privacy masking obscures detected faces in supported streams while leaving useful scene context visible. The right configuration depends on who views the footage and why.

How it works

Automatically obscure detected faces in supported video streams.

Where it could help your business

Review office activity while limiting unnecessary exposure of identity.

Ask whether masking happens before recording, only during viewing, or only on exported clips. Check who can see the original stream. Test side profiles, people at the edge of the frame and crowded scenes for missed masks.

What your camera setup needs

Confirm where masking is applied, who can access originals and how missed detections are handled.

Does face masking make a recording anonymous?

Not necessarily. Clothing, location and other details can still reveal identity. Masking is one control within a wider privacy and access arrangement.

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.

Privacy masking: 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 = exports × video minutes × (manual − assisted labour ratio) ÷ 60

Worked example (illustrative inputs)

10 exports; 30 video minutes; 2 old; 0.5 new.

staff time released: 7.5 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.
  • Results must not drive automated punishment, pay deductions, access denial or employment decisions. Use requires appropriate notice, a lawful purpose and human review of every exception.

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