Sony SNC-RZ30N ptz? remote host path?

[bjohnston]

Has anyone had success setting up a Sony SNC-RZ30N camera with Zoneminder? Everything looks straightforward until I try to set up a monitor for it, I have been unable to look up or guess what the proper remote host path is for zoneminder to pick up the image stream?

What do you get in a browser when you right click on top of the streaming image and select properties?

[bjohnston]

well, interestingly enough, i had no luck doing that before, but i see now that if I right-click when it is using java applet and/or active-x to render in the browser, right-clicking does nothing. but after reading your comment I went back and also tried 'server push' option and right-clicking gave this under properties:

http://192.30.161.13/image?speed=0

[cordel]

If this camera uses activex, then it will not work with ZM unless you can grab a still jpeg. This of course it not the prefered mode but Linux does not support activex.
Check the manual and see if there is a way to get mjpeg, if not then the only way would be to capture still jpeg images.

[bjohnston]

well, it's funny. it's the only camera i have that offers to open in a java applet viewer, an active-x applet viewer, and a server push applet viewer.

the active x viewer is only available as an option if using Internet Explorer, but when using Firefox it still offers java or server push

after your initial comment i tried this in the remote host path:
/image?speed=4

and it appears to work & give me 4 fps. i had to turn on the camera's built-in memory function though to get it to work this way, so it seems i am grabbing still jpgs from the camera. not sure. no luck getting the ptz functions to work though, unfortunate as this is the fastest ptz i've ever used.

if you can get hold of or have the protocol for thic cam it can be added to zm, but zm needs to know what to tell the cam to do.
I assume then from your post that you have zm now grabbing images?

[bjohnston]

Hi, yes. I have the snc-rz30n working using the remote path that I mentioned above. Seems to be no lag whatsoever and I can specify whatever frame rate I want by adding it as a parameter in the remote path.

As far as the control script, can you have a look at this link, I think this is the one needed? Question, can I add this into my system myself (I know nothing about programming) or do I wait for it to be added in at a future release of the zoneminder software?

[jameswilson]

its of no use to me bbut one of the other lads might bbe able to use it. There was abbit on here a bit ago about creating your own ptz file but dont knopw where it is

good luck

[zoneminder]

Thanks for the link. I will take a look and add it in, though I can't test it without access to a cmaera. I am half way through rewriting the PTZ control stuff so it should be easier to add in future anyway.

I've just started working with the SNC-RZ30N and ZM also. The manual mentions a CGI reference guide and to "consult your authorized Sondy dealer."

Currenly Google lists one here.

Hope it helps.

I have a network-attached SNC-RZ30n that I've been dying to get a control script for, but sadly, only a serial-attached script was provided by ZM. So, using it as a bit of a reference, and also the PDF manual provided by goreo95033, I whipped up a functioning control script.

Code: Select all

As it states, it is a use-at-own-risk script, but it works for my camera. As a suggestion, it would be nice to add a [near] and [far] button on the zooming feature that will zoom all the way in/out (con-zooming) and then just use the current arrows for step(rel)-zooming. This script uses the timeout to do step pan/tilt/zoom to overcome the continuous mode default.

Adding the script:
Copy the script to /usr/local/bin/zmcontrol-visca.php
Be sure to: chmod a+x /usr/local/bin/zmcontrol-visca.php

Make sure controllable cameras is enabled in the config.
Open your camera monitor page, then click on the control tab.
Enable 'Controllable' on the camera.
Click "Edit" next to Control Type.

The <user>:<passwd>@ only needs to be used if you have set up security users and an admin user/password, since normal users don't have CGI access to move the camera around...

Once you save your camera, you can now use the ZM controls to spy on those people in the parking lot...

PS. ZM, this might be something to review and include in next version. I know you're rewriting the control code a bit, but this works in the meantime.

Let me know if I missed anything.

[squartochi]

I have an SNC-RZ30N. I am trying to get the control going. I did what was stated above. Just wondering if the new version of zone minder crippled this script?
Thanks,

[ammaross]

Yes, the new version crippled this script. It is written for 1.22.x. If I was better at the new scripting system (and perl for that matter), I could write an updated one. However, I'll leave that to someone with more know-how than I. All the control information can be gleaned from my script though.

[depe]

I found this perl project, may be could be usefull ?

http://search.cpan.org/~cmorris/SNC-Manipulator-0.30/
I thnk is written in perl.

Best Regards.

Curious if anyone revisited this?

I'm bringing one of these cameras online as a cheap PTZ and wondered about the control software. I'm about to tackle it but was curious if anyone had already cut a path.

Cheers!
