I was involved with winter home watch and small maintenance
for 30 years as a self employed service at a summer resort. So,
I have had experiences with several security systems & companies.
Wired systems vs wireless:
Both need to be monitored by a central.
Both experience breakdowns and need repairs. The big names in the
business, ADT for one, is good on installation, but slow on making
trouble calls. OTOH, smaller (local) outfits seem to be Johnny-on-the-
spot when we called in for service. My observation: wireless systems
go bump in the night more than wired systems.
Technology moves pretty fast, just like computers, so be aware that
your system may be antiquated by the 3rd or 4th time the serviceman
comes, ready to sell you a "new and improved" system.
I liked the simple systems; control box, interior infrared motion detectors,
fire detection (extremely worth while) and freeze protection if the house
was vacant for long periods with the water left on.
Most outfits will tout wireless, mostly b/c they can install the systems
much quicker thereby getting a better bottom line.
You will have false alarms with any system. The cat will climb the
drapery, the kids will break a window while playing ball, a draft will
cause the burglar detection to activate, components will fail, rats
can eat the wires...you name it.
You have access to all the same parts as any other installer and can
build your own system, which I have done, with results as good as
commercially available. Depends on your mechanical expertise, and
you still need to use a monitoring central, to call the cops, or fire dept.
Mostly, the compromise is that your life will not be the same once you
go electronic, and there was one customer who just refused to use his
new system after he found out how inconvenient it was to his lifestyle.
We used the system to monitor the freeze and fire protection only.
I think that about sums things up from my experiences.
Me ? I don't live in a large city, and will not consider putting a system in.
I'd rather get a JY dog, to be honest.
