AP-GTR1000 embedded GPS
based NTP Server transmits GPS time information to IP based application server like
as CCTV VMS which requires accurate time information. Legacy GPS Time Receiver products only
support RS232C Interface but AddPac AP-GTR1000 supports fast ethernet port as well as dual RS232 interface for backward
compatibility.
AP-GTR1000 embedded GPS
NTP Server is easy to
manage remotely and provides excellent scalability. This device can be applied
to various real-time video applications such as video surveillance, traffic
management and monitoring for disaster prevention
In local area
network, this device transmits GPS based time information to application server
like as CCTV recording server by using NTP (Network Time Protocol) protocol. Without
GPS based time synchronization or NTP server, if time is passed after
installation or in service, each application server’s time clock is mismatched
comparing with GPS based real-time. Especially, in case of CCTV application,
time mismatching should be solved between real-time and CCTV application
server’s current time.
For fault tolerant GPS NTP service, Linux or Window based
application server support primary and secondary NTP server configuration as
follow example. Using dual AP-GTR1000 NTP server, a user can implement fault
tolerant GPS NTP service.
