The Grandstream GVR3550 is a powerful Network Video Recorder (NVR) that offers small to medium businesses (SMBs) and residential users a reliable solution for surveillance recording. It provides video recording, indexing, searching and video storage management for up to 24 IP video cameras. This allows users to record and monitor their IP video surveillance network from one device. The GVR3550 supports not only all Grandstream IP Video surveillance cameras and IP Video Encoders/Decoders, but also all ONVIF compliant IP cameras. This ensures interoperability between the hardware regardless of manufacturer. Users can view the live feed of up to 16 cameras simultaneously by connecting the GVR3550 to a TV, computer monitor or through remote access. Save up to 16TB of video files on the NVR by connecting up to 4 SATA 3.5� internal hard drives. Users can also set their system up with either RAID 0 or RAID 1 configurations for redundancy.
