Open to checking
Every result comes out of resolution, field of view and distance to DIN EN IEC 62676-4. The arithmetic is shown beside it, and you can follow it with a pen.
Plan CCTV. On a figure, not a feeling.
Anyone who has compared camera data sheets knows it: a dozen PDFs open, megapixels everywhere, and still no idea whether a face at the gate will be recognisable. cctvfinder turns that around. You describe the spot; the tool names the models that reach the required pixel density there.
The right camera in seconds.
Instead of an afternoon spent reading data sheets.
Basis
A standard, not a rule of thumb.
The arithmetic follows DIN EN IEC 62676-4, the standard for video surveillance systems. It turns a task into a figure, and that figure sits behind every result: something you can hand to a tender, an insurer or an assessor.
Calculated to DIN EN IEC 62676-4.
Built by engineers who plan and assess these systems themselves.
Distance, height & protection goal.
Done.
cctvfinder takes care of the optics behind it.
What it does
Six things that make up the tool.
For your spot, not in general
Sensor width, field of view and slant distance add up to one requirement. Everything is calculated against the distance, height and object width you set.
Out of assessment work
It grew out of planning and assessing video systems. What the tool calculates is the same path an assessor takes on paper.
Figures from the data sheet
The field of view enters the calculation as the manufacturer measures it. Derived from focal length, real varifocal lenses come out at a different angle, by factors.
18 sensor formats & 20 resolutions
From 1/3″ sensors to full frame, from Full HD to 8K. Panoramic and multi-sensor formats are in there too, whoever makes them, sorted by what suits the task.
3D view
A yard, a warehouse aisle, a shop entrance, a petrol station. The scene turns, and the camera image beside it holds exactly as many pixels as the sensor delivers at that spot.
Quality levels
Every task has its figure.
Is it enough to get an overview of a site, or do you need to assess a person’s identity? Between those two tasks lies a factor of 75 in pixel density, from 20 to 1,500 px/m. cctvfinder calculates against the level you need, not against the highest one.
