GV-SNVR1612 is a standalone network video recorder with Linux embedded that records video files directly to the internal hard drive and supports up to 16 IP camera channels for video surveillance. GV-SNVR1612 has built in 16 PoE (IEEE 802.3af) ports that simultaneously provide network and power to IP cameras. Thanks to its up to 4K resolution video output, GV-SNVR1612 eliminates the need of a separate PC to view and play back video from the unit. It has USB ports that can be used to import or export system settings, update firmware, store snapshot files and back up videos.
