Technical Context
The NVR's independent PoE ports provide power and network connectivity to each included camera through a single Ethernet cable, simplifying deployment. Ultra 265, H.265, and H.264 compression helps manage bandwidth and recording storage, while ONVIF support allows compatible third-party cameras to be integrated into the four-channel platform.
Installation Notes
Connect the four EC-B4F28M-V3 cameras to the NVR's four PoE ports and install a compatible SATA HDD before recording. The cameras operate from -30°C to 60°C, support a wide voltage range of ±25%, and provide IP67 protection for outdoor use. HDD is not included.
