Operation common information
Processor must be connected to the PC for the settings, control and Update and Upgrade.
(The rear panel RJ45 connector)
The Processors have built-in system time synchronization. The control computer is
synchronized from the source time signal and in turn synchronizes the Processor. The
processor provides a timing signal that is synchronized receiver. In case of loss of signal
synchronization whole system will work, but showing the wrong time. DVCrypt program will
write this in the server log.
Environment Requirement
Environment Temperature 5~40 (sustainable)，0~45 (short time)，
Installing air-conditioning is recommended
Power Requiring device power, air-conditioning power and lighting power are
independent to each other. Device power requires AC power 220V 50Hz. Please
carefully check before running.
Machine Hall Floor Electric Isolation, Dust Free, Ground anti-static material.
Grounding Requirement
Good grounding is the basis of reliability and stability of devices. Good grounding are the
most important guarantee of lightning arresting and interference rejection.
Coaxial cable’s outer conductor and isolation layer should keep proper electric conducting
with the metal housing of device.
Grounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device’s frame should be no less than
25mm2.
