HOW TO INTEGRATE 2 AVP101 PTZ CONTROLLER???

[no_one292000 0]

Anyone? has an idea how to integrate or parallel connect two(2) avp101 to control lots of cameras, without jamming signal when using both ptz controller,

 

i just simple parallel connect their wires, etc.... i came about jamming the signal passing through the ptz cameras, both controller broadcasting same signal when using both, so when running two diffrent cameras with both controller their going nuts.

 

anyone has an idea??

 

avp101 doesnt seems to have a slave and master capability.

Hello!

 

I am not sure what you are looking for. No matter how you connect up two keyboards you are going to get "interference" from the two.

 

Do you have two separate "stations". You might set up a multiplex system so that only one can control the camera.

 

If this is on a budget then there is not much that you can do. You will have to let them decide who has precedence, and just wire them in parallal.

 

Some keyboards have a DVR input, and then the output goes to the camera. I do not know if this keyboard has this feature or not. I wonder if wiring the first keyboard in to the DVR input would work a little better?

THANKS scorpion,

 

yes im using two stations. what im trying to do is:

 

1.controller 1 and controller 2 can control all ptz cameras.

2.controller 1 and controller 2 should not have interference.

3.controller 1 and controller 2 will not control one camera at a time "no worries, i told operators to do so".

 

yes avp101 have a dvr input which can control the dvr, but unfortunately the that dvr input(rj11-rs232 on dvr side) sends the same protocol and baud rate as it sends on its ptz port, meaning its dvr and ptz port throws the same data.

 

but i haven't tried the 1 controller directly to dvr. hope it will works, thanks for the suggestion.

 

multiplex system i think wont help it. because my requirement was to control all ptz with both controllers.

What types of PTZ cameras are you using? Do they support multiple protocols as some do?

 

My thought, crazy as it might be, would be to configure one controller to use one protocol and the other controller the second protocol.

 

Also, does this controller allow you to set different camera numbers to the actual camera address?

Excellant ideas Harrar!

 

You have touched on a few tricks of the trade! Now that this information is out to the general public they will have no use for us installers. LOL! OK I kid!

 

He wants the PTZ to be controlled by both stations which would require them to change protocols on the fly.

 

I believe he wants to control the PTZ from both stations as a global setting, but wants to have one station to have precedence over another station.

Here is what I would do based on a low budget solution.

 

On the wire controlling a PTZ I would install a relay. Both keyboards can control the PTZ. When the higher precendence keyboard needed to have full control of the PTZ then the relay can be engaged taking the other keyboard off line with just this one PTZ.

 

If you install the relay on the line with the lower precedence keyboard then you can take it offline, and it would not be able to control any PTZ.

 

You would have to turn the relay off to allow it to interact with the PTZ again.

 

It may be better to put a timing circuit that allows the relay to engage for a set time frame and then release the relay. This way no one can forget to turn a switch off leaving the relay engaged, and the lower precedence keyboard locked out from a PTZ, or all of the PTZs depending on how it is wired in.

How are you at designing circuits?

You can take 74 series ICs and create a logic set up that allows both Keyboards to pass a signal to one PTZ, or a group of PTZ. The circuit will allow one keyboard to take full control.

 

You can use a digital relay to be controlled by the IC circuits.

 

What do you think?

Thanks scorpion,

 

i think this might work, but im not that good on circuit, though i cracked few on my college years.

 

i might need some few refresh on it.

 

yeah thats true this is a low cost setup.

 

i will post again hopefully if i make the circuit.

I think you may have found a new source of income by selling this device!!

 

LOL!
