Hi All, Im from Ireland and have found the site very useful over the last while, Car alarms aren't installed to the same quality and an alarm install could cost easly a 1000euro for a high end alarm if not more, My last alarm for example an Gemel (?) has been draining my battery ever since, so after install alarms for friends and family for the last year im am replacing my own, My Question is this, DEI Viper 791vx or the Compustar 2WSS-AS I love the Range of the Compustar but the DEI seems to have better addons such as the Radar Module ETC. These "Plug and Play"modules are the main appeal of the DEI. I am also well aware of the Warrenty issues but there are not Registered dealers for either in Ireland so its not relivant for myself, Any advise would me much appreciated... Thanks

My preference is DEI, others will swear by the Compustar products. Keep in mind that most of the DEI accessories that you would want to add can be added to any manufacturer's system. If you want to add the Radar module made by DEI(508d?), you can use it with a Compustar system.
Hope this helps.

How does real world range compare between the two? I'm trying to decide on an alarm and have been seriously considering the Viper 5000 but what good is a paging alarm if you don't get range. Open to suggestions here.

The Compustar kills the DEI on range before you get into the entire real world argument, the DEI is 1/4 mile (400m) and the computstar is on paper 1.25miles (2KM), for me this is the real appeal of the Computar.... There seem to be no side by side feature set comparison available, i may look into drawng one up and posting it here to help people decide..

From reading the Wiring manual for the Viper and there site info this is the comparison i could come up with based on the features listed for the Compustar, please update if you know a unknown feature is there on the Viper or there is a Viper specific feature not present on the Compustar left out, Right now i am leaning towards the computstar if i can use the DEI backup battery and Siren with it Features Compustar DEI 791xv

Personal preference would be to the COmpustar. I've installed DEI stuff before and they are well made, but I'm not a fan of the relay harnesses they use.

The only feature listed above that the 791 doesnt have is the temp sensor, everything else it has. As well it has tach and volltage sensing. If I was looking at a DEI product I would wait until the SST version comes out as it should hit the market very soon. It will have a mile on range on it and is suposed to have a more stable reange than the compustar

Hey Ravendarat, Will that be an upgraded model of the current 791 or a new series altogether, do you knwo where it will be placed in relation to the 791, will this be within the next 3 months, also so you know if the 791 has the EST2 capability.

Can anyone with a DEI paging alarm chime in with the range that they normally get. I've heard people get a few thousand feet off the Compustar in close to ideal conditions, but haven't heard anything about DEI's range. Maybe DEI's 1/4 mile range is a much more practical estimate compared to Compustar's? Also, I like that DEI features code hopping. What does Compustar do to prevent this? This could very well be the deciding factor for me because they both cost about the same and support pretty much the same features.

They didnt say what the model number would be but they did say that the standard responder wasnt going away and they were going to run both lines for the next year with the SST model being approx 50 dollars more. It is gonna be on the market by the end of July at the latest baring any unforseen problems. The range on the DEI piece being a quarter mile under ideal conditions is very acurate as long as the ground is under the 10 ohm tollerance. The DEI pieces are quite sensitive to poor grounds which is one of the only problems I have with them. ------------- double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Compustar will be coming out with a new system this year as well along with newly designed 2 way remote controls and one way remote controls. I've seen the prototypes remote controls and they're pretty nice looking. Range may also increase as well with the new systems but is not confirmed.

Did they design and build this BEFORE or AFTER they bought Astro? -------------

I heard about this technology being developed last year. They only bought astro a couple weeks ago. The plans for now are to run astro as a completly seperate company for now, different tech departments different R&D teams etc. I dont know how long it will last but thats the plan for the immediate future. ------------- double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

they have been working on their SST units for about 2 years now....supposed to be released last fall but didnt want to with little gremlins still in the units... they are being field tested as we speak and should be ready to hit the dealer price lists and actually shipping by end of Q2...... dont be surprised by them buying their competition... they have already done this years ago with Avital, Clifford, Design Tech...... ------------- Kevin Gerry

People where talking about the range of the 2 r/s's earlier. I have a compustar and my buddy has a viper. We both work in the same place and park at about the same place. He has to be able to see his car before he can start it. As for me i can be inside the building and it works. And when you use a cell in here you get crappy reciption. But my remote works great.
