Brightly-Colored Details Even at Night

No one can easily sneak in under the cover of darkness. Choose between the color mode and the infrared mode as you'd like. Or, set the camera to the “smart night vision” mode so its vision will automatically switch from black-and-white to full color upon motion detection.

Night Vision Range:

Black and White: Up to 30 m (98 ft)
Full Color: Up to 15 m (49 ft)

H.265 Video Technology
