Are you sure this command has worked before? There are a lot of RoboB actions missing to get it work
Or maybe you have posted the wrong code
1.
RoboB.Focus is not a action to bring the browser window in front
2. You have no Robobrowser in your command selected (created)
3. You have no camera URL specified which can open in the Robobrowser window
4. because you write "... login to my camera system ..." - there is also no action to select a login field or similar
Here is a example how you can start from:
<?xml version="1.0" encoding="utf-16"?>
<!--VoxCommando 2.2.0.7-->
<command id="632" name="Automatic Front Door Camera" enabled="true" alwaysOn="False" confirm="True" requiredConfidence="0" loop="False" loopDelay="0" loopMax="0" description="">

and here also a short Videotutorial (not my best, but maybe this will show you the principle of RoboB plugin):
