The most common question in computer-vision projects is whether new cameras are needed. For many safety and operations use cases the answer is no — provided a few criteria are met.
Six criteria
| Criterion | Usually sufficient | Watch out for |
|---|---|---|
| Stream access | RTSP or ONVIF | Closed cloud-only cameras |
| Resolution | 1080p (2 MP) or higher | Small objects or long distances need more |
| Frame rate | 10–25 fps | Fast vehicles or conveyors |
| Angle | Elevated, angled view of the subject | Strict top-down views for PPE |
| Lighting | Stable light or good IR | Backlight, glare, steam |
| Network | Same local network as the analytics device | Bandwidth and VLAN limits |
Why camera angle matters
| Use case | Preferred view | Avoid |
|---|---|---|
| PPE | Angled from above, person reasonably large in frame | Top-down or very distant views |
| People counting | Overhead or steep angle at the entrance | Side views where people overlap |
| Fall detection | Side or angled, full body visible | Areas hidden by racks |
| Forklift–pedestrian | Wide view of the whole crossing | Blind corner outside the frame |
Pixel density
What matters is how many pixels the object covers. People-level events at moderate distance usually work at 1080p; glasses, gloves or small defects need tighter framing.
Test, don’t guess
Short sample recordings from each candidate camera are run through the model during assessment, so suitability is measured rather than assumed. Request a camera assessment.

Evaluate your camerasFrequently asked questions
Can different camera brands be mixed?
Yes, as long as each provides an RTSP/ONVIF stream.
Is it enough to re-aim an existing camera?
Often, yes. A small change in angle can improve results significantly without new hardware — but security recording needs must also be considered.
