Thanks for the answer. I think making a blank detector with different labels will do the job.
I just noticed that here are 2 forums and I posted twice! Google magic. Previously I thought that my post has been removed
P.S. Your motion detectors are perfect!
Hi, I want to create custom detector like "break glass detector" or "move detector". I can modify existing detectors but I don't know how to change its symbol visible on plan view like "SD" or "HD". Thanks for your help.
