    A customer contacted us via chat this morning with the following issue related to controlling a PTZ camera from a joystick and iPhone. Below is a transcript of the chat.

    Customer:

    Hi I have a joystick controlling my ptz cameras (4 in total). I also have the cameras setup to view via my iPhone.

    Only issue I have is ptz can only be controlled through joystick and not iPhone.

    How can ptz be co trolled with joystick and also through iPhone ? I tried to piggyback the red black to dvr from joystick but then only control went to iPhone how can they both be used to control?

    I basically want to add iPhone PTZ controls without losing the joystick controls at the DVR.

    CCTV Support:

    So, please confirm. Your DVR currently supports iPhone PTZ controls, yes?

    Customer:

    Yes.

    CCTV Support:

    Also please confirm. You are saying that when you run the RS-485 from the camera to the joystick it is OK, but if you go RS-485 out from the joystick to the RS-485 in on the DVR, the joystick no longer works?

    Customer:

    That is correct the joystick gives control to iPhone

    CCTV Support:

    Does your DVR have an RS-485 input for a joystick? or a serial port for joystick?

    Customer:

    It has the A and B inputs

    CCTV Support:

    and also an RS-485 output?

    Customer:

    Correct

    CCTV Support:

    So, I would recommend trying 2 things.

    1) Confirm when you did it the original way, that when you went to control via joystick, the iphone connection was closed.

    2) Try going RS-485 out from the DVR to the camera, and RS-485 in from the joystick to the DVR.

    Customer:

    Ok so have dvr primary then the joystick piggyback… Sounds like good idea Yes, I will try that and if any issues ill chat back.
