This allows the camera to provide effective monitoring in low-light conditions while offering flexible lighting modes for different surveillance scenarios. The camera delivers up to 3840 × 2160 8MP resolution at 20 fps, with H.265/H.264 compression and Smart H.265+/H.264+ technologies for more efficient bandwidth and storage usage. 120 dB WDR, 3D noise reduction, BLC and HLC help maintain image quality in challenging lighting conditions. For intelligent surveillance, the IPC-HFW2849T-ZAS-IL provides human and vehicle classification, SMD Plus, intrusion detection and tripwire functionality. It also includes a built-in microphone, microSD storage support, alarm I/O and PoE/12V DC power options. The metal housing provides IP67 protection, while the camera is also available with IK10 impact protection. Its operating temperature range of -30°C to +60°C makes it suitable for demanding outdoor installations.
