companies that i have used over the years
1)scytek
2)compustar
3)DEI
4)autopage
5)JBS Technologies (bulldog)
6)audiovox
heres my intake on the units.
Scytek, very cheap and durable unit for its price. it performs really well, good battery life and it does do the advertized range about 2500ft paging. the only issue with this is the unit is very chunky in size and the remotes have a very cheap feel and look to them.
Compustar, the best unit i have ever used. has all features taht you can think of and with passive arm, RPS knock pad, nice ergonomic control that is very stylish and amazing on battery life. The rage is superb and i ONLY use the pro versions. installed the normal 2w900fm - as, but they are nothing compared to the Pro series. Also, compustart understands that people do drive manual cars and offer tranny specific models for those manual cars. A reservation mode must be entered to allow the car to start and it ensures the vehicle is not in gear. - smart thinking compustar !
DEI, very well known and trusted for their units and tech support (authorized dealers only). they have up to date wiring charts which is nice. they are known as the high end alarm systems. you might have heard of Viper, Clifford, Avital, Astrostart etc. they are all one company and each unit is just branded differantly. THey have nice remotes, lifetime on relay packs and brains which is nice. Too bad they dont offer a manual safe unit for any car. because of compustars manual safe start systems, DEI made the 689m. a NEUTRAL SAFETY SYSTEM, where the user must enter a reservation mode just like compustar systems, but it means you have to spend more money. the paging on the units are delayed up to 10 seconds on some units. the advertized range is kinda BOASTED for what those units can really do. the ease of use would be a 10/10.
Autopage, super micro remotes take up no room in your pockets at all. Buttons are sometimes a PIA to get to if you got big ass fingers. Screen quality is very good, high res and real time paging just like compustar. the unit is fairly small, they offer all features that other units would offer except the manual safe tranny, unless they have somthing new. btw i dont really use autopage anymore so not really updated with their products so bare with me. range on these are superb. tech support is very good.
JBS Technologies (bulldog), super cheap units, i guess its reliable, range sucks, but hey it does the job for under 150 for a paging system. and they offer manual safe units ! btw they went bankrupt for a while so their tech support sucks balls. the guy that is talkin to you wants you off the phone.
Audiovox - older audiovox units are very dependable and very easy to install and use. these units are comparable to scytek. Unless you have the new CODE ALARM OLED pager, that is just as good as the compustars base line, if not better ! well thats all i have to say and hope you learned something. one day im goin to do a full review on the units i have used and installed.
BTW, i use a compustar P2W900FM - AS
