Can your existing CCTV run AI analytics? Here's what actually matters

Executive Summary

Not every camera can run every detection model. Resolution, mounting angle, lighting and NVR compatibility all matter more than the AI itself. Here's what we actually check before saying yes.

The question we get asked most isn't "does your AI work", it's "will it work on my cameras". That's the right question, and the honest answer is: it depends, and it depends on things that have nothing to do with how good the AI model is.

Resolution matters more than people expect

Most detection models need enough pixels on the object or person you're trying to detect, not just on the overall frame. A camera can be "1080p" and still give you a blurry, low-resolution view of a specific zone if it's mounted far away or has a wide field of view covering a large area. A hard hat at 15 meters on a wide-angle lens is a different problem than the same hard hat at 4 meters on a focused lens, even on the same camera model.

Mounting angle and height change what's detectable

A camera mounted straight down from a high ceiling sees the tops of heads, which is fine for counting people but bad for reading PPE compliance or facial direction. A camera at a 30-45 degree angle at a reasonable height usually gives the best balance for most detection types. This is exactly why we don't give a blanket yes or no over email, it depends on your specific site.

Lighting is the quiet dealbreaker

Consistent lighting matters more than bright lighting. A loading dock that's well-lit at noon and nearly dark at 6pm will give an AI model wildly different input depending on the hour, and models that aren't tuned for that variance produce either missed detections or false alarms. Infrared/night mode switching cameras handle this differently than fixed-exposure ones, and it affects what we can realistically promise.

NVR and stream access

Even when the camera itself is capable, we need a way to actually pull the video stream, whether that's RTSP access, NVR export, or a cloud VMS with an API. Some older or locked-down NVR systems make this harder than it should be, and that's a compatibility question separate from the camera hardware itself.

This is why we do a feasibility review first

All of this is exactly why we don't sell first and figure it out later. A feasibility review means someone actually looks at your camera specs, placement, and NVR setup, and tells you in writing what will and won't work, before you spend anything. Sometimes the answer is "this camera works great for intrusion detection but won't reliably catch PPE at that distance", and that's a more useful answer than a blanket yes.
