EN Camera Series
24 Tutorial
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.
3.5 Static IP Address Assignment
The factory default IP assignment is static IP= 10.0.0.65. The user must change the IP address of the
camera. There are four methods to change the static IP address: EN setup software, Telnet, serial
terminal using the debug RS-232 serial/power cable, and BIOS/Monitor using the debug RS-232
serial/ power cable.
