The DS-6716HFI 16-Channel Video Encoder from Hikvision supports H.264 compression technology that allows you to save on storage space while also minimizing the bandwidth requirement for operations. This encoder is capable of simultaneous dual streaming of the H.264 and MJPEG video feeds at 30 fps (NTSC) up to 4CIF resolutions. The encoder features one independent PoE network interface and is connectable with network HDD in NAS, IPSAN mode. Features: H.264/MPEG4/MPEG2/MJPEG encoding standards supported Up to 4CIF real-time encoding One PoE network interface for DS-6701/6704HFI models Connectable with network HDD in NAS, IPSAN mode Support multiple network protocols, including IPv4/v6, HTTP, HTTPS, QoS layer3 DiffServ, FTP, SMTP, Bonjour, UPnP, SNMPv1/v2c/v3, OnVIF, PSIA, SOCKSv4/v5, etc.; Multiple PTZ protocols Specifications: DS-6716HFI Video/Audio input Video Compression: H.264/MPEG4/MPEG2/MJPEG Video input: 16-ch,BNC (1.0 Vp-p, 75 Ω) Audio compression: G.711 Audio input: 16-ch,Line input interface(2.0 Vp-p, 1 kΩ) Two-way audio: 1-ch, 3.5 mm audio (2.0 Vp-p, 1 kΩ) Video/Audio output Audio output: 1-ch, 3.5mm interface (Linear, 600 Ω) Encoding resolution: 4CIF/2CIF/CIF/QCIF Frame rate: H.264/MPEG4/MPEG2 encoding: 25 fps (P) / 30 fps (N); MJPEG encoding: 15 fps Video bit rate: 32 Kbps ~ 3072 Kbps, or user defined (Max. 8192 Mbps) Audio bit rate: 64 Kbps Dual Stream: Support Stream Type: Video/ Video&Audio Network protocols Protocols Supported: IPv4/v6, HTTP, HTTPS, QoS layer3 DiffServ, FTP, SMTP, Bonjour, UPnPTM,SNMPv1/v2c/v3(MIB-II), DNS, DynDNS, hkDDNS, NTP, RTSP, RTP/RTCP,TCP, UDP, IGMP, ICMP,DHCP, ARP, SOCKSv4/v5, PSIA, OnVIF, HIKCGI, netFilter Data storage Type: NAS, iSCSI, IPSAN Capacity: 32G for microSD storage External interface Network interface: 1 RJ-45 10 M / 100 M /1000 Mbps adaptiveEthernet interface Serial interface: 1 half-duplex RS-485 interface1 RS-232 interface Alarm in: 16 Alarm out: 4 General Power supply: 12 VDC Consumption: ≤ 22W Working temperature: -10°C~+55°C(14°F~131°F) Working humidity: 10%~90% Dimension(W×D×H): 440 × 45 × 274mm Weight(without HDD): ≤ 4 Kg
