Veracity TIMENET Pro
TIMENET Pro GPS Master NTP Time Server inc. antenna is now field upgradeable and boasts reduced power consumption, updated NTP software providing improved security including protection against DDOS, plus encrypted password protection. Even smaller than the previously available version, the antenna driver voltage is switchable between 3V and 5V allowing a wider range of GPS antennae to be used, as customers frequently use specialised antennae in certain applications (such as marine systems). The software will incorporate some new features such as encrypted password protection and logging of GPS lock, time sync and sync requests from external devices. Make sure that your "closed" Surveillance network is just that, and doesn't rely on an open port to the internet for synchronisation with MS Windows or another 3rd party NTP provider.
