3. Analysis of Video Signal Loss
Under the video and PTZ cloud terrace control with Analog Video Signal connecting in and being
displayed formally , press 【1】 to procure parameter of Video Signal, it includes.
1) Maximum Vpp: Difference value between Maximum value and Minimum value of video signal
solidity, the larger of the value is, the brighter the screen display is.
2) Average Vpp: indicates video signal strength difference between the maximum and minimum
values of the average.
3) Synchronizing level: indicates the synchronizing level Video Signal strength, it is used to test
coaxial cable's resistance. For example, if camera's synchronizing level is 0.3V(generated by
connecting CCTV tester and camera）,after transmit in a exact distance , synchronizing level
dEscends to 0.21V(generated by CCTV tester), in this case, it means that video signal solidity
decayed for 30% and user procure the resistance of coaxial cable.
4) If there is no video signal access, it will indicates “NULL” .
4. Screen setting
At mode of video and PTZ cloud terrace control, press【set】key to enter into screen setting .

“ x” means open circuit
If the connecting2 cables result
show “x” ,there are 2 situations:
1. Both of lines in open circuit.
2. Both of lines in short circuit.
