Veracity UK Ltd used Linux to build a tiny time server for security camera networks, among other applications. Veracity's TimeNet sets it own clock via GPS, and runs an open source NTP (Network Time Protocol) daemon that network clients can query for highly accurate time settings, the company says.

Targeting CCTV surveillance and digital video recording (DVR) applications, the TimeNet is far less expensive than typical standalone server-based products, says Veracity, and more suitable to harsh environments. The device is based on a Digi International's minuscule “Connect ME,” a tiny embedded Linux system little larger than a standard RJ-45 jack, yet replete with an ARM7 processor, 2MB of flash, and 8MB of RAM. It draws less than 1 Watt of power.

The TimeNet sets its own internal clock via GPS, and comes with a small GPS antenna suitable for window placement. Running open source NTP software, the device provides enough accuracy for “evidential” timestamping by network security equipment, the company says.
