Every point has a job
The entrance camera exists to capture an image good enough for identification. The till camera balances the detail of the transaction against the privacy of customer data. The stockroom camera watches movement. And the street-facing storefront needs its own treatment for glare, lighting, and a wider field of detail. Treating all four as interchangeable is how a store ends up with footage that shows something happened but never shows who.
The coverage model
We start from the pedestrian entrance, the point of sale, the display floor, the stockroom, and any service entrance. If there is parking or a vehicle entrance, we add a dedicated scene for the plate — we do not ask the storefront camera to do both jobs at once, because a camera framed for a wide storefront cannot also read a plate reliably.
Points a store plan should cover
- Entrances and exits
- The till (point of sale)
- The stockroom
- The storefront and the street
- The loading area, if there is one
Resolution and recording
ABTech uses a design baseline of 8MP and 30 days for stores facing a public street as a starting point — not a final figure. From there we confirm the actual classification and the real retention period according to the activity, the applicable requirements, and the competent authority. The number that ends up in your quote should be the one calculated for your site, not a round figure copied from another project.
Frequently asked questions
How many cameras does a store need?
The count is driven by the functional points, not by floor area alone. A small store may need four points or more depending on its stockroom and its entrances.
Are 30 days enough?
It is an initial design point for some cases. The actual retention period must be set according to the site's classification and the real requirements, not assumed.
