Turn a compute module into a NAS or NVR. The Interceptor Carrier Board takes a Raspberry Pi CM4, a Raspberry Pi CM5 or a Banana Pi CM4, so you can start on a CM4 and move to a CM5 on the same board later.
You get five SATA III ports with hot-plug and software RAID 0, 1, 5, 6 and 10 (mdadm), a 4-port Gigabit managed switch, dual 4K HDMI and standard 24-pin ATX power. Add one or two Interceptor PoE Boards for up to 16 PoE+ ports (10/100 Mbps).
With a CM4 or CM5, start from Raspberry Pi OS, Debian 12 Bookworm or 13 Trixie, or Ubuntu 25.10 or 26.04 LTS and add the Exaviz packages from apt.exaviz.com for the switch, PoE and network setup. See the Interceptor software guide. The Banana Pi CM4, with its 5 TOPS NPU for AI on the module, runs its own Exaviz OS image and drives one HDMI output; that image is still available but no longer being developed.
With a CM5: the board's USB ports are USB 2.0, and a CM5 boots from USB 3.0 only. A CM5 whose eMMC has never been written boots from the microSD slot. To use a CM5 with an initialized eMMC, flash it on a Raspberry Pi IO Board first. The front power button works with a Raspberry Pi CM4. The FAQ has the details.
