Megapixel Speed Dome Camera Instruction Manual
The terminal resistor is used for the following cases.
 In case that the control cable length between a camera and a
controller is relatively very long (1:1 Connection)
If the communication cable length is very long, the electrical signal
will bound in the terminal point. This reflected signal causes
distortion of original signal. Accordingly, the camera can then be out
of control. In this case, the terminal resistor of both sides i.e. the
camera and the controller must be set to „ON‟ state.
 In case that multiple cameras are connected to a controller
Due to similar reasons with the case 1, the terminal resister of the
controller and the last camera must be set to „ON‟ state. The last
camera means the camera farthest in cable length from the
controller. Do not turn on the terminal resistor of more than one
camera on the same communication cable.
