    Hello, Could I interface the same PTZ camera to a second DVR controller and control PTZ from both using RS-485 ? Thanks, df

    The original installation is as shown in the previous posts' diagram. To this, an new encoder is added connecting to the loop thru of the first encoder via BNC. This new encoder is viewed by a new NVR. The PTZs in question are outdoor Dome PTZ. Thanks.

    The new NVR is a different brand and does not support the original encoder. Thanks again.

    Gentlemen, you are right, normally you would not use a new NVR - however this is the situation. There are reasons that I cannot giveaway really. If it was an IP PTZ you would be able to control it with the software, but this is an analog PTZ, don't you need RS-485 ? Thanks.

    All cameras are analog. I am introducing an NVR (not DVR, sorry for the confusion I have caused) + encoder that has an RS-485 interface. Are you suggesting that I should daisy chain the new to the old, just making sure they have different ids ? Thanks.

    The new encoders + new DVR are there to view and control the analog PTZ from the Internet. The old encoders + old DVR will remain for inhouse use. The PTZs are currently cabled to the old ones via RS-485. We need to cable the same PTZs to the new encoders as well. Thanks, again.

    Well, yes one would usually be enough. The new encoders have some extra features, or let's say are used by a different group of people monitoring the same cameras. We are required to add the new and keep the old one as well, and try to control PTZ from both systems. Thanks again.

    Thanks for your reply. The new encoder is there to provide access from the Internet. The existing one will be used for inhouse surveillance. We need to keep both, and both of them have RS485 connections. Thanks, df

    Thanks for your reply, it is a commercial installation. These analog PTZs are already cabled to a certain encoder and controlled by a DVR and working. I have also installed a different brand encoder and DVR with some other features. I have connected the BNC in parallel and I have picture OK. I would also need to control this from the new encoder/DVR. How can I connect the new encoder to the existing RS-485 connection and have both controlling the PTZ at the same time. Thans again. df
