GV-SNVRxx12 is a standalone network video recorder with Linux embedded that records video files directly to the internal hard drive and supports up to 16/8/4 IP camera. GV-SNVR1612 has built in 16/8/4 PoE (IEEE 802.3af) ports that simultaneously provide network and power to IP cameras. 
Thanks to its up to 4K resolution video output, GV-SNVRxx12 eliminates the need of a separate PC to view and play back video from the unit.
