  3. Resistance of single wire with 100 meters shouldn’t exceed 10Ω.
  4. Cable twist density should reach Cat5 standard.
  5. Cable flame resistance and flexibility should reach national standard.
  6. Suggest you use waterproof type cable to ensure the image effect and long time use in the outdoor environment.
  7. For general project application, recommend to use the three pairs of one UTP cable to transmit three signals, letting the remaining one pair lines reserve or for grounding operation.


Cable Connection

  1. Twisted-pair cable can’t be connected with strong voltage cables together and when connected to the strong current equipment, keep the distance.
  2. Cable connection can adopt connector, welding, twist ground, and should ensure that the connection is firm and waterproof.
  3. The cable length form camera to transmitter should be as short as possible, permitted within 20 meters.


Product Use
