Product description

Monitor your property with the 8-Channel 4K UHD NVR with 2TB HDD and 8 4K Outdoor Night Vision Bullet Cameras from Lechange. The 4K NVR manages and can record from up to 8 cameras. It comes preinstalled with a 2TB HDD. HDD storage is expandable to 6TB if more space is required. The Lechange app for iOS and Android enables remote viewing.

The included bullet cameras use a 1/2.5" progressive scan CMOS sensor to capture 3840 x 2160 resolution video at up to 15 fps. Their 2.8mm fixed lenses each have a 112° horizontal field of view. Each camera has 2 IR LEDs to deliver up to 131' of night vision. Integrated PoE technology simplifies connectivity by enabling the transfer of power and data through a single cable. Additionally, ePoE technology offers a cost-effective solution for transmitting power and data over long distances via Ethernet or coaxial cables.
