I have a EVD D31 which does not seem to work from zm 1.22.1. Things tried so far:- libvisca downloaded & installed

Code: Select all

chmod 777 /dev/ttyS0

just to be sure then

Code: Select all

[root@zm examples]# ./testvisca /dev/ttyS0
Some camera info:

Setting pan tilt absolute position

camera moves arround and does what it is supposed to, at least this proves my serial port is working!!
Then start zm add a monitor with control enabled and control type Sony VISCA and control device zmcontrol-visca.pl and control address 1 i assume this refers to the VISCA address not the serial port /dev/ttyS0 or /dev/ttyS1 . I have tried a control address of both 0 & 1. When I start zm with debug set to 9 in the log I get

which I assume means zm can't find my zmcontrol-visca.pl, now if i type

Code: Select all

[root@zm examples]# zmcontrol-visca.pl --device=/dev/ttyS0 --panspeed=254 --panstep=9381 --command=move_rel_right
[root@zm examples]#

it looks like at least the code worked although the camera does not move & if i type

Code: Select all

[root@zm examples]# zmcontrol-visca.pl --device=/dev/ttyS3 --panspeed=254 --panstep=9381 --command=move_rel_right

Can't call method "baudrate" on an undefined value at /usr/local/bin/zmcontrol-visca.pl line 96.
[root@zm examples]#

the code barfs which it would as i have no /dev/ttyS3 & shows that the 1st script using /dev/ttyS0 seem to be working although still no camera motion.
The zm-visc.log gives

It does seem odd that zm can't find zmcontrol-visca.pl.
Any further things I should try before giving up & going back to using my trusty axis 2400 to do the serial control?

It seems odd that while the file exists, zmfix can't find it. Check your folder permisions because if zmfix can't find the file then the other zm scripts can't either.
Also make sure your running as the webuser.

It's been quite a long time sincce I used this script. I will get my old Visca cam out and see if I can reproduce this problem.

[johnnyzone]

Things appear a little better, it seems I misunderstood the 'Main tab' in the 'Control Capability' page where it says 'Type', the only way I could see 'Sony VISCA' for my monitor was in 'Local' but the EVI-D31 gets into ZoneMinder via an Axis 2400 video server on the network so the 'Monitor/Control/Control Type' will only show network capable PTZ scripts.
I then added a new control with the 'Type Remote' and copied all the default settings from the default Local VISCA control & named it 'Sony VISCA R'.
This now allowed the control to show up in my 'Monitor/Control/Control Type' dropdown, but as posted above it dosen't work.
I have since used one of my other 'Local Monitors' and added 'Control Capability' with 'Control Type Sony VISCA' & 'Control Device /dev/ttyS0' & 'Control Address 1' and it works (sort of), at least I'm able to pan/tilt/zoom the camera with the ZoneMinder window while viewing the camera in an Axis browser window although the picture in the ZoneMinder window is of the static local monitor.

How dificult would it be for me to modify the appropriate script to allow my 'Monitor setup' window to allow a remote monitor ie. my EVI-D31 via the Axis video server to use a 'Control Type' of the local variety? or.....wait for it is it possible to have a 'zmcontrol-visca-via-network-to-axis-2400.pl' script to actually send controls to the Axis box via html on the netwotk & let it send the serial commands to the camera....

Thanks for the quick responses & Phil I don't think you need to get your VISCA cam out.

Cheers

I have read a little on the axis servers but i think you pass axis teletry commands to them over ip then tell the video server what telemetry to pass through its 485 port

[cordel]

That can be set in the database in the Controls table. If you look at the structure it should make since to you. You can even use the existing zmcontrol-visca.pl file. It just has to be put in the database as a new line and set to remote instead of local.

Code: Select all

mysql zm
mysql> select * from Controls where name='Sony VISCA';

ill explain my post a bit more. Basically you send axis coammds over ip from your zm server to your axis server. You then connect the 485 port (assuming you have one) to your telemetry reciever of you ptz unit. I think you have to buy protocols for the axis server but the may offer some basic free ones. The other option is to copy accross the req protocol to an ip named one. Then connect your 485 lines to your zm server serial port in the usual way. But if you want to pass telemetry over ip to your axis server tahn im afraid (i think) the first option is the only way to go.
