Vera VistaCam PT Control

Post by NewfD90 »

Recent Vera refugee here. Transition went remarkably smoothly. Some things were harder; others easier. Regardless, I couldn't find a way to control the Pan and Tilt controls on my old Vera IP camera, so I fired up WireShark and figured out the controls. Below is a simple bash shell script that implements all those controls. Attached is a screen cap of a control screen that implements some of these functions.

Code: Select all

#!/bin/sh
IP_ADDR="userid:pass@192.168.1.1:PortNum"

case "$1" in
        left)
                curl http://$IP_ADDR/decoder_control.cgi?command=4
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        right)
                curl http://$IP_ADDR/decoder_control.cgi?command=6
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        up)
                curl http://$IP_ADDR/decoder_control.cgi?command=0
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        down)
                curl http://$IP_ADDR/decoder_control.cgi?command=2
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        upleft)
                curl http://$IP_ADDR/decoder_control.cgi?command=90
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        upright)
                curl http://$IP_ADDR/decoder_control.cgi?command=91
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        downleft)
                curl http://$IP_ADDR/decoder_control.cgi?command=92
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        downright)
                curl http://$IP_ADDR/decoder_control.cgi?command=93
                sleep 1
                curl http://$IP_ADDR/decoder_control.cgi?command=1
                ;;
        vpatrol)
                curl http://$IP_ADDR/decoder_control.cgi?command=26
                ;;
        stopvpatrol)
                curl http://$IP_ADDR/decoder_control.cgi?command=27
                ;;
        hpatrol)
                curl http://$IP_ADDR/decoder_control.cgi?command=28
                ;;
        stophpatrol)
                curl http://$IP_ADDR/decoder_control.cgi?command=29
                ;;
        pos)
                curl http://$IP_ADDR/decoder_control.cgi?command=$((30 + ($2*2-1)))
                ;;
        *)
                echo "Syntax:"
                echo "    up, down, left, right"
                echo "    upleft     : up and left diagonally"
                echo "    upright    : up and right diagonally"
                echo "    downleft   : down and left diagonally"
                echo "    downright  : down and right diagonally"
                echo "    vpatrol    : vertical patrol"
                echo "    stopvpatrol: stop vertical patrol"
                echo "    hpatrol    : horizontal patrol"
                echo "    stophpatrol: stop horizontal patrol"
                echo "    pos N      : recall stored position N"
                exit 1
                ;;
esac

exit 0

My security camera plugin has an action to send a URL to a camera. Might be worth a try. It is completely untested function since I don't a camera to take commands. Would be happy to work with you to get it working if you are interested.

I saw that capability in your plugin. However, for each movement, the camera requires the requisite command, followed by a stop command. The time in between defines how far the camera moves. So to do that within Indigo seemed a bit complicated, hence the script.

Thanks though!

Couldn't you create an action group that would issue the first command then issue the stop with a delay. For example, a 10* clockwise action and a 10* counter clockwise action.

OK, I was going to play with this, but the Action for sending a command via URL is no longer there! I swear I saw it yesterday, but maybe that was just from reading your manual.

I just posted version 1.5.4 that fixes the issue of the Camera Command action not being displayed. Thanks.

Got it and updated. Unfortunately, urllib doesn't like the URL. I'm sending a fully formed URL of the type http://user@ipAddr:port/path, which best I can tell seems to be what urlretrieve expects. Does any of the special characters need to be escaped? Perhaps run it through urlencode first?

Try the urllib2 option in device setup. It has separate fields for user name and password. It is also a bit more resilient than urllib. Also, the http:// is assumed and does not need to be included.

That's how I have it setup. However, the plugin is coded to only use urllib for the CameraCommand call.

Just a point of interest: we highly recommend using the requests library (included with Indigo 7+) for all http communication - it handles all authentication types, it's easy to use, extremely robust and very well supported.
