Where to get the control script

Here!

How to get the Control Script Ready

Unzip and untar the files somewhere. Copy the zmcontrol-ptel.pl file to /usr/local/bin.

Make it executable. You might need to be root to do that:

shell> chmod +x /usr/local/bin/zmcontrol-SNC-M3W.pl.

With your favorite editor, go into the zmcontrol-ptel.pl file and edit the serial port information - the linux device node of the serial port your camera is connected to.

The default line looks something like:

my $device = "/dev/ttyS0"

Replace this with your serial port. Serial ports are tricky - see below

Remember to save the file when you're done.

Setting up the control in ZM

<DONE TO HERE FOR NOW>

First, you'll have to "Install" the control by following these steps. From the ZM Console, click on the source link of the monitor you created for the camera. It's listed as the IP address of your camera. When you click it, it's configuration page opens in a new window.

Now click on the "Control" Tab. Put a check mark in "Controllable".

Here you need to look closely - on the next line, marked "Control Type", there's a pulldown. Next to the pulldown to the right, there's a link named "Edit".

Before you can use this new control script you downloaded, you have to create an entry for it by clicking on "Edit".

A new window opens that shows you all the types of control scripts ZM knows about. In this window, you need to press the "Add New Control" button.

A newer window opens that shows you all the things ZM needs to know about a Control Script. Here's what to put in there:

In the first Tab, "Main", enter the following values.

Don't forget to Click Save!!!

Done! Close all the ZM windows in reverse order, reopen a Monitor window for your camera, and look for a link in the upper left of the window that says Control. When you click on it, the camera controls will appear and you're in business! Pan and Tilt away...

Using the control in ZM

In the monitor window, you'll now have a "Control" link in the upper left. Clicking it gets you the control panel below the video window. Clicking the arrows moves that camera.

Click a preset to make the Camera slew to that preset position; Click the Preset "Set" button to pick a preset and save the current camera position into that preset.

The Center X centers the camera.

Other nifty commands implemented in the control

Since I wanted to make the camera play nice with Internet Explorer users, I programmed the Power, Wake, and Sleep like so:

Wake - This switches the camera into MJPEG streaming mode, since this is the format ZM can capture video from the camera.

Sleep - This switches the camera into MPEG streaming mode, so when there are no ZM users accessing the camera, IE users get better sound quality in MPEG mode.

Reset - Same as Sleep mode.

So, huge note:

You won't get any video in ZM unless you manually set the camera into "JPEG" mode using IE in Windows,

or you PRESS THE "WAKE" BUTTON IN ZM!!!
