![]() There are two banks of switches on the PTZ labeled S1 and S2 in the manual. There's also nothing wrong with matching the address to the channel number, for some it's easier to remember which camera is which this way. The camera can be connected to channel 7, and have an address of 3, this is perfectly normal. If a command is received without the correct address, it is ignored.Īlso, the address of the camera has nothing to do with what channel of the DVR it is connected to. So to know when the controller is talking to it, the camera listens for it's address. Set the Baud Rate to match on both the camera and DVR.īecause RS485 operates like a bus, every PTZ connected to the controller is sharing the same connection. The camera can't understand it's commands if they are sent too slow or too fast. With any camera or controller, it is a good bet that one or both of these will be supported. The most common and well supported protocols are Pelco-P and Pelco-D. Currently none of our DVR's can use this protocol. This is the manufacturer's proprietary protocol, and unless the controller can use the same protocol, we'll need to change that. Out of the box the PTZ will be set to it's manufacturer's default protocol, D-MAX. ![]() To control the camera, it and the controller need to be speaking the same language. There are at minimum three things you should set on the camera. The camera has several dip switches to control the protocol and address it will operate on. Replace or rerun any broken cable.Īll RS485 connections should come back to the same home point, either at the DVR or a keyboard. If you still cannot control the PTZ, use a cable tester to check for continuity. In this case correct theĬable polarity at the camera or DVR. This connection is polarized, and if reversed will simply not work. Check the dip switch on the camera, and settings in the DVR.Ī two wire connection is required to control the PTZ. The camera may also be mistakenly set to PAL instead of NTSC, or the DVR is set to PAL. If you are receiving a picture but it is distorted or discolored, check your cable run to make sure it is not running too close to high EMF fields. If the camera is receiving power, but not displaying any video, use a coaxial cable tester to verify your RG59 cable is good. More than 31VAC, the power supply may be faulty.Īlso watch the camera video when it is powered on, the camera will show how many volts it is receiving, and inform you if there is an If you're getting less than 23VAC you may need to run heavier gauge wire for power. ![]() It should be within 23 ~ 31 VAC for the camera to operate properly. Use a multimeter to check the power coming into the camera. If the answer to all of these is correct, than move on to the Programming section.
