Basics
TR-D4251WDIR2 v2 2.8 is based on a 1/2.8" CMOS sensor with 0.003 lux sensitivity. It is equipped with a fixed focal length lens of 2.8 mm, a horizontal angle of view of 91°, a vertical angle of 66°, an aperture of F/1.8, an RJ-network port. 45, audio in, audio out, microSD slot up to 128 MB Supports day/night mode with ICR: when there is enough light, the filter blocks IR rays, optimizing color reproduction, and in the dark it mechanically moves away from the sensor to increase its sensitivity. - 12 V DC, PoE Maximum power - 4.6 W Size - Ø102.2 × 56.4 mm Weight - 310 g.
