Probably, but with an honest answer they can make that decision.  I have
some very good clients who spend a lot of money with me because I try to
think about their issues and give them the best information I can.

P.S.  I just installed a system in a site that had an old Monitronics
labeled panel.  (You want it back?)  I was all prepared to be impressed.
The installer had fished a contact down inside the aluminum frame of a glass
door frame.  Very nice.  Contact was inside the header totally concealed,
and the mag was glue in place in the top of the door.  Then I walked to the
back and they stabled the wire down the wall (crookedly) and stuck a surface
mount directly to the steel door and frame.  Oh, well.  I guess I was only
half impressed. LOL.

Half the site look like it was done by a high end installer who cared, and
half looked like it had been done by a lick and stick hack.
