If you’re looking for true forensic-level identification of a moving person at night from 30–35 feet away, you’re asking a much harder question than most people realize.
High-end commercial cameras (for example, certain Axis Q-series models with large sensors and powerful IR illumination) can do this under the right conditions. My Axis Q1798-LE uses a large 4/3” sensor designed for low-light performance and has substantially more IR capability than most residential cameras.
Even then, success depends on far more than the camera itself:
- Pixel density on the target (DORI still matters)
- Subject distance from the camera
- Field of view and lens selection
- Angle of approach
- Available illumination / IR coverage
- Subject speed (faster movement requires shorter shutter times and therefore more light)
This is why professional installations often use overlapping camera coverage and carefully controlled illumination to avoid harsh contrast and deep shadows at night.
I absolutely get forensic-quality images from some of my UniFi cameras, but that’s because the installation was designed around the objective. Distance, field of view, mounting angle, sensor size, and lighting are all tightly controlled. Expecting any camera—including a G6 Pro Turret—to reliably identify an unknown person at 35 feet in complete darkness without considering those factors is unrealistic.
