The camera is used as a twisted pair (cable) transmission, or with a dedicated video cable (SYV75-5) transmission is good? Which experts advise. Thank you! Because I now have no points, the next must reward points. More
Dedicated video line is the analog video, network cable is compressed digital video, which is two things.
According to the current number of estimates, know the power, it is not difficult to know the current bar commonly used in the square of the square per square millimeter is 5A, more than ten square you reference the circuit breaker instructions, there is a table (circuit breaker selection and nominal wire cut Area, I think you should understand it, such as 2.5 square is 20A of the circuit breaker, it will be able to withstand 20A current) three-phase power general security per kilowatt 2A estimate
800 fire cable bridge bracket boom should adopt L40 * 4 angle steel, cross should be used 6 # channel. If you want to use the wire to do the words, it is appropriate to use 10-12mm through silk.
Will the three-phase selection of electric wire square root with the power between how to choose?
