DS-2CD3121G0-I is a 2 MP IR Fixed Network Dome Camera featuring a 1/2.8″ progressive scan CMOS image sensor and 1920 × 1080 resolution at up to 30fps. It supports 2.8 mm, 4 mm, and 6 mm fixed lens options, with up to 40 m IR range for low-light monitoring. The camera provides BLC, 3D DNR, HLC and DWDR for image enhancement, along with line crossing and intrusion detection for behavior analysis. It supports three video streams with H.265/H.264 compression and offers IP67 and IK10 protection.
