TR-D4221WDIR2 v2 2.8 is built on a 1/2.8-inch CMOS sensor with 0.005 lux sensitivity. Supports day / night mode with ICR: in sufficient light, the filter blocks IR rays, optimizing color reproduction, and in the dark it is mechanically shifted away from the sensor to increase its sensitivity. Equipped with a fixed lens (focal length - 2.8 mm, horizontal viewing angle - 101°, vertical - 55°, aperture - F / 1.8), RJ-45 network port, integrated microphone, slot for microSD up to 128 GB. Power supply - DC 12 V, PoE. The maximum power consumption is 4 W. Size - Ø102.20×56.38 mm. Weight - 310 g.
