BNC Loop Test:
The Tester can send and receive color bars through the Tester’s
Video Out and Video In ports, which can be used for testing
transmission channels. The Tester’s Video Out port can connect
to the optical terminal’s output port, and the Video In port can
connect to the optical terminal’s receiving port.
A. When maintaining the dome camera, the Tester sends out
the color bar via its BNC output to the monitor at the
monitoring center. If the monitor receives the color bar, the
video transmission channel works normally. Based on this,
the monitoring center can evaluate whether a transmission
is experiencing loss or interference.
B. The Tester sends out a pure color bar (white and black) to
test for bright or black dots.
