RF alarm system that will transmit over 2 city blocks.

locked area. I haven't had many serious problems but recently my RV was
vandalized. Currently I do have a motion detector that sounds an alarm. This
works if I can depend on one of the people who lives close by to call me or
the police when the alarm sounds (in this case, the vandilizer was obviously
surprised by the alarm and didn't get any farther than doing some damage)..
I do have some neighbors in that area who are looking out for all the RVs in
that parking area but what I'd really like is a battery powered motion
detector that will reach me immediately at my house about two blocks away if
there is a break in.. I'm really interested in something that doesn't use a
lot of battery power but will broadcast to a remote if there is a violation
of the area (the inside of the RV). I don't want anything that requires 500
or 1000 dollars to install.. I'm looking for a simple motion detector that
I can place *in* the RV and, if activated, it sends a signal to a remote
unit that alerts me 2 blocks away. I don't want anything other than a
sensitivity settable motion detector inside the RV because I don't want ANY
false alarms. Does anyone know of such a device on the market?

Ben, don't know offhand of an off-the-shelf unit that has the
motion detector and the transmitter in one unit - but the pieces
to do what you want are certainly readily available. For
instance, a quick Google on 'car alarm pager' turned up the
following: http://www.autotechs.com/items/item82.htm which would
take care of notifying you at your house.

Ben,
Here's another one that Google turned up. Sounds _almost_
like what you're asking for.

Thanks, but that site has zero technical information and I was looking for
something that people might of used rather than a "Quick Search".

I have used a baby monitor transmitter in my unit for years. I take the
receiver with me and I can hear anything going on at or near the unit. I have
also found that using the FRS two way radios are very useful. Put one on VOX
operate in the unit and take the other with you. The range is well over two
blocks.

the FCC's very restrictive power limits on non-licensed transmitters.
Probably the easiest thing would be to put a VOX capable FRS radio in the
coach so that it could broadcast the siren to you. Not strictly legal but a
man's gotta do what a man's gotta do.
Let me suggest another approach. Make it impossibly painful to stay in the
vehicle. That's the approach I've taken in my restaurant. I have 2 100 watt
police sirens installed, one at each end of the dining room. Even with ear
muffs and plugs it's uncomfortable. Within 10 ft of a speaker it pegs my 130
db capable sound meter. So far it has thwarted one "smash'n'grab" (he smashed
but he couldn't take the pain to grab :-) and probably thwarted another
(smashed the laminated safety glass in a door. Glass broke and bowed but
didn't give way. I figure the alarm drove him off before he could take a
second shot with the concrete block.)
The installation is simplicity itself. There is a relay driven by the alarm
panel output. It switches 12 volts from a small car battery to the siren
drivers. The panel contains a float charger that keeps the battery up. All
exposed wiring is in conduit so it can't be quickly cut. The speakers are
recessed in the ceiling so the wires aren't exposed.
One siren would do the job in your RV. There are now some very compact folded
horn siren speakers available, designed for use on compact cars that some PDs
are using. Hiding one under a bed or in a cabinet with the horn facing out or
down through a hole would work. I can't even imagine what the sound level
would be like inside an RV!

Something along this line *might* work. It'd also keep dog piss off yer
tires. It was on ebay and I forget the price, but it wasn't alot cuz I
thought about getting it.

available from Sears and not very practical inside the RV.

Alan's second link but I'll need to dig in for tech specs to put it together
with a motion detector. I'd rather have had a turn-key system but looks like
it doesn't exist. BTW, FRS radio won't work unless I connect it to a voltage
regulator then to the battery as I don't want to be going to the RV to
change the AA batteries every other day. Even if I made a battery source to
the FRS radio and had one that keyed-up with audio, I'm sure I'd still get a
lot of garbage on the channel even set to a sub-channel recognition.
Looks like I need to ad this to my list of projects..
Thanks,
Ben

I have one of these paging alarms in my tow truck and it works fine.
It will make a slight ringing sound for the silent pager. I have it
hooked up to the door switches and it also has a motion trip switch
which is adjustable in case someone tries to tow it off. Fairly easy
to install if you are handy. I think the range is 2500 ft.
