3.4 Time Synchronization

The EN camera supports NTP (network time protocol) synchronization. If you disable NTP by clearing

the “NTP Client Control” register, then the internal clock will drift approximately 1.5 seconds per day.

To reset the clock, set the “Real Time Clock” register to your current local time.

If you decide to take advantage of the NTP feature, make sure to set up the NTP server, preferably with

GPS input. This guarantees that the clock drift is within 10ms. Set the NTP server IP-address registers

up to 3 NTP servers. Then, enable “NTP Client Control” register. Reboot the camera.

After rebooting the camera, check the “Real Time Clock” register to check if the current time is

properly set. Note that this time is GMT.

If the NTP drift file is empty, then the NTP will take about 1 hour to optimize the time. During the

initialization, “NTP Status” must show USYNC, and “NTP estimated error” is max. After 3-4 hours,

the time drift will become within 10ms. Check “NTP estimated error” and “NTP Status” registers again.

“NTP Status” must be showing “PLL.” This means that NTP is finally synchronized properly.
