Hi IVB:
Is your presentation for the general public, or aimed at "technical" oriented people? I'm thinking for the general public, a self install will be to much for them! Most people don't understand how a simple switch works, let alone install their own security system. Of course they have an option for a professional to do it, which is what I would suggest they do.
Anyway you might want to emphasize:
1. List or contact some professional installers to get an idea of their pricing and requirements for products they install in your area as these type of questions are surely going to be asked.
2. List some simple type of self install security system for the non-technical person.
Speaking of that, I need some simple security device for my son's apartment when he goes back to college in August! It would be nice to have a stand alone system, sort of like the one mentioned above, but not require drilling into a door lock. It would also be nice if it could dial out or send messages via the internet they will have.
Regards,
BSR
