Physical Description
Rear Panel
Status LED’s
Each time Network Camera starts up, it will perform power-on-self-test, abbreviated as
POST, to examine every hardware module. As soon as the administrator plugs in the
power connector both LED’s under the power LED will flash one by one until the diagnosis
is done. If the result is good, both status LED’s will turn off for a while and then follows
the pattern below. If any module fails, refer to the Appendix A for the error pattern and
follow the trouble-shooting procedures. If the system still cannot operate normally,
please contact your reseller for technical service.
