Applications

The DS-2CD2146G2H-ISU with a 4mm lens is ideally suited for monitoring corridors, parking lots, building façades, and locations with an increased risk of vandalism. Compared with the 2.8mm variant, the 4mm lens offers a narrower viewing angle (81° vs. 107°) but a greater effective range, keeping people and vehicles clearly visible at a greater distance. The IK10 housing makes this model particularly suitable for environments where physical protection of the camera is essential.
