Long time lurker, first time poster.

RS 485 has long been the way to control PTZ cameras, but recently UTC has been gaining ground and I love it.

But I have a problem with a new zoom camera, which is only UTC and I need it to be wireless.
Now, I have a wireless transmitter for RS485, but not UTC, so I'm thinking there might be a RS485 to UTC converter.
I have searched, but not found.

Does anyone know of it?

Alternatively, can someone point me in the right direction for the UTC protocols?
I might concider making my own.

Camera is AHD with UTC only.
Hoping to be able to connect an RS485/Pelco D joystick to it, if possible

Ok makes sence.... So you don't have a PTZ camera ??

Your looking for control over the coax
Do you have data connection on your camera

Sorry for explaining badly.

In the system, I have several PTZ cameras, controlled by RS485/Pelco-D with joystick.
This new cameras requires me to use a secondary controller for UTC, which I find inconvenient.

Hi. Can you post a link to your camera

If you have a AHD camera then it should have data conection for ptz control

Utc control would not be needed for a ptz
Utc is a coax plug in for accessing osd on camera setup

Are all your cameras AHD

I have some special-case analog cameras that I'm not willing to change for AHD yet because I got some arduino with OSD info, but rest are AHD (Once I solve OSD with AHD, those analog cameras are gone).

AHD camera in question is this: http://www.novuscctv.com/en/products/21 ... 5202H_IR-1

Wow talk about you confusing your own post.

So your not using a PTZ at all.

Are you using a AHD dvr ?? You don't need the UTC ..... Cam control is also on dvr

Sorry for the confusion.

The problem is still relevant even if this one camera only has the Z, not the PT.
Yes, some DVRs can use UTC to control the UTC cameras, but many of my cameras are not UTC.
Also, the PTZ controller embedded in the DVR is not good.
So I use separat RS485 joystick for simplicity.

And thus I am looking for a way to communicate with the UTC camera, using the same joystick as the rest, which are proper PTZ dome camera.

It will not work .... cam does not have a address or Chanel or baud rate or protocol at camera.... and the came needs them to communicate.

Your other problem is your cam is not a continuous zoom...... not made to be moved in or out like a camera with zoom control


UTC controller is only used to setup cam at camera end and then removed
