Frequently Asked Questions

Q: Does the digital peephole door viewer camera work in complete darkness?

A: Yes! The advanced low-light super night vision function allows the camera to capture clear color or black-and-white images in very low or no-light conditions. It emits no visible light or heat, so it operates completely discreetly without alerting visitors outside.
