IR night vision uses built-in infrared LEDs to illuminate the camera’s view when visible light is low or unavailable, allowing the image sensor to capture nearby details. The camera typically switches to a black-and-white image in these conditions, while visibility depends on the camera’s IR range, scene layout, and obstructions.

IP dome cameras with IR are available with fixed 2.8 mm lenses, motorized varifocal lenses ranging from 2.7 to 13.5 mm, and PTZ designs with 3.42 to 6.85 mm varifocal lenses and 2x optical zoom. Choose a fixed lens for a consistent viewing area and straightforward installation, a varifocal lens when you need to adjust framing or zoom, or a PTZ design when the operator needs to change the camera’s direction and zoom remotely.

IP dome cameras with IR typically connect to a PoE network through an Ethernet cable that carries both network data and power, reducing cabling for the installation. Compatible network video recorders and video management systems can discover the cameras over the network, receive video for recording and monitoring, and use ONVIF support where provided for integration with open-platform systems.

When specifying IP dome cameras with IR, compare resolution, fixed or varifocal lens options, field of view, wide dynamic range (WDR), IR night-vision distance, and low-light image performance. Also review PoE and other power options, local or cloud storage, analytics, and enclosure ratings such as IP66 or IP67 for weather resistance and IK ratings for vandal resistance, based on the installation environment.
