A Networking Video Recorder (NVR) is designed to record and playback videos from multiple IP cameras usually connected over Ethernet, and in many cases powered over Ethernet (PoE). The main purpose is for security applications allowing caretakers to monitor multiple cameras at the same time on a mosaic screen.
There are plenty of turnkey NVR solutions on the market, but SoliRun, an embedded systems company known for its modules and single board computers, recently introduced the ClearFog GTR A385 family that supports up to eight PoE/PoE+ Gigabit Ethernet Ports.
- SoC – Marvell ARMADA A385 dual-core Armv7 (Cortex A9 class) up to 1.3Ghz
- System Memory – Up to 2GB on-board DDR3L
- Storage – 8GB eMMC flash (default), 2x 7 pin SATA (optional replacement for 2 x mPCIe slots)
- 1x 1GbE WAN supporting up to 802.3bt type 4 PD PoE
- 1x SFP up to 2.5GbE
- GTR S4 only – 4x 1GbE switched LAN supporting 802.3at/af/bt (up to type 4) PSE PoE
- GTR L8 only – 8x 1GbE switched LAN supporting 802.3at/af/bt (up to type 4) PSE PoE
- USB – 1x USB 3.0 port
- Expansion – 3 x mPCIe (1 x mPCIe supports LTE), GPIO header
- Debugging – 1x Micro USB port for serial console
- Misc – Indication LEDs, user push-buttons, fan header, RTC battery
- Power Supply – 12V DC input or 48V-54V input DC jack when PSE supported
- GTR S4 – 177mm x 110mm (board)
- GTR L8 – 253 x 132 x 32mm (enclosed)
- Temperature Range – -40°C to 85°C (industrial)
Marvell ARMADA 385 (A385) processor should have pretty good software support as it is used in Turris Omnia open-source router, and SolidRun ClearFog Pro board relies on a similar ARMADA 380/388 SoC. Having said that the developer page is light on software resources at the time of writing. The solution should still be more much flexible than on typical NVR platforms where you do not usually have the option to customize the software.
Both board support a maximum of four PSE PoE++ 802.3bt ports up to 90 Watts each, and up to four or eight PSE PoE+ 802.3at/af ports up to 30W each. It looks like this can be used for daisy-chaining multiple boards, and increasing the number of cameras powered by a single PSU.
