How many pixels per metre are left at the distance written down

A camera does not “see” further: it loses pixels per metre. Below are the figures we measured.

  • Identifying a person You can tell a police officer who it is.

  • Recognising a face you know You recognise someone you already know.
    The distance written downat 8 m 125Pixels per metre See the cameras
  • Observing what a person is doing You see the gestures, not the face.
    The distance written downat 15 m 62Pixels per metre See the cameras
  • Detecting that someone is there You see that someone is moving, nothing more.

The drawn scale goes up to 300

The figures are measured by us on the cameras in stock, at the light level written in each sheet.

Frequently asked questions

The questions we get most often before an order, answered once, in writing.

Is your question missing? Write to us and we will add it to the list.

Will I really recognise a face at 25 metres?

No, and no camera does it at any resolution. At 25 metres few pixels per metre are left: you see that someone passes. For a face you need a camera closer in or with a narrower angle — in the table on this page we write exactly how many pixels per metre are left at each distance.

How long is the footage kept?

As long as you decide and as much as fits on the disk. On this page is the sum on the figures we measured: GB per day, how many cameras and how many days. The retention term is written down and kept to, not left to the disk.

Will the cameras fit on my switch?

It depends on the switch’s watt budget, not on its port count. Send us its model and we will work it out together with the figures from the camera sheets.

Do I need a sign at the entrance?

Yes, if other people walk through the filmed area. The sign goes before the filmed area and says who the operator is.

Will the camera work on my internet, without a recorder?

It will, but then the footage sits with the maker, on a subscription. If you want the images on your own premises, you need a recorder and a disk.

Can I have a business invoice?

Yes, with a tax number. For large projects write to us and we will send a quote with the bill of materials.
