  • Page 18 Addendum Appendix 1. Lightning proof and surge signal proof The product uses TVS lightning proof technology to prevent damage from a lightning strike below 1500W and impulse surge signals. It is also necessary to take note of the following precautions to ensure electrical safety for all applications.
  • Page 19 Addendum - The system must be grounded with equal potentials. The earth ground connection must satisfy the anti-interference and electrical safety requirements and must not short circuit with the high voltage electricity connection. When the system is grounded separately, the resistance of the down conductor should be <4 Ohms and the sectional area of the down conductor should be <25mm 2.
  • Page 20 Addendum If the user selects thinner cables or installs the camera in an environment with strong electromagnetic interference, or connects lots of equipment to the RS485 Bus, the maximum transmitting distance will be decreased. To increase the maximum transmitting distance do the opposite. 2.3 Connection and termination resistor- The RS485 standards require a daisy chain connection between the equipment.
  • Page 21 Addendum 2.4 Problems in practical connection- In special circumstances it may be necessary to adopt a star configuration to achieve the best connection. the termination resistors must be connected to the two items of equipment that are farthest away from each other, such as items 1 and 15 in Figure 39. As the star configuration does not conform to the RS485 standards, problems such as signal reflections and lower anti-interference performance may arise when the connecting cables are too long.
