Frequently asked questions
How does 4MP compare to the 2MP version?
Sharper detail at the same zoom level and distance — useful for reading number plates or faces further from the camera, at the cost of a larger video stream.
Does it detect people and vehicles automatically?
Yes — IVS perimeter protection plus face detection, and Acupick for locating flagged targets in recorded footage.
Is it suitable for outdoor use?
Yes — IP66 rated with TVS 6000V lightning and surge protection.
