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.
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.
So, please confirm. Your DVR currently supports iPhone PTZ controls, yes?
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?
That is correct the joystick gives control to iPhone
Does your DVR have an RS-485 input for a joystick? or a serial port for joystick?
It has the A and B inputs
and also an RS-485 output?
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.
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.
