What is the Low-illuminance Camera?

The Low-illuminance Camera(which belongs to the Bullet Fixed Focus Camera) refer to the surveillance camera(which contains the Fixed Focus Bullet Camera HD) that can still capture clear images under the low illumination condition. Generally speaking, the illuminance of most cameras(which contains the Bullet Fixed Focus Journal Camera) are at 0 Lux or 0.1 Lux.
