Topic: Compustar Spread Spectrum Encryption?

Subject: Compustar Spread Spectrum Encryption?
Date Posted: September 04, 2004 at 8:16 PM

Recently I was in a few local car audio shops getting things like ring terminals and wire for an install I am working on.  2 of the shops had salesmen that noticed my alarm remote and asked what kind of alarm I had.  After I told them they said "oh ya, you know that they're not encrypted and someone can grab your signal and unlock your car when you walk away, people in the states have been caught".  Now these guys are DEI reps (hardly anyone sells compustar here) and I don't have much faith in local salesmen.  But I just wanted to see if anyone had any comments on this.  I know that if someone wants your car bad enough they're going to take it no matter what you have but I'm just curious about the details on this.  I would assume if anything the SS technology would be harder to "hack"  than FM but I don't know for sure.

Any opinions or comments are appreciated.  Thanks.

I can assure you that the equipment is available. But, in the real world alot of factors would have to be going in the thiefs favor to do so.

1. This assumes the thief is within range, when and if you are entering or leaving your vehicle. Unless, you're a hard target for some *special* reason, that would not occure.


2. This would not help a theif if the vehicle was set to arm passively. As no code or signal is being sent during your leave.


3. Code readers that can be bought over the counter cannot *capture* both AM, FM, wide band signals, while capturing the actual code whether it be static or dynamic. The working distance that I have seen first hand is less than 25 feet, and that is pushing it


4. They are prone to capturing invalid generated numbers, erractic numeric values that extend past 12 digits, while in the area of communication towers, automated door openers, etc.

Regardless of the above, everyone should start with a proven lifestyle change, and proven quality product(s) first which is layered in redundancy, then follow up with an experienced installer(s) who understands your needs, and how to best to integrate those needs in practical terms during the installation process.

Sadly, the system you have indicated, and its maker, is not one them.

Here's a little something from the maker's of Compustart:

Firstech, LLC. has dedicated enormous amounts of revenue and spent countless hours developing the new 2WSS-Series (Two-way Spread Spectrum Series). This ground- breaking technology uses a transmitted signal that is spread over a wide frequency band and the transmitter abruptly changes (or hops) the frequency in accordance with a pseudo random sequence. CompuSTAR uses 50-channel frequency hopping at 900MHz. This revolutionary technology allows the CompuSTAR transmitter range to extend up to 1.25 miles. The FCC allows much larger power usage in SS technology because many transmitters can share the same band without interfering with each other.

Firstech LLC is not the maker, nor have they spent countless hours developing anything.

They are simply the North American importer / sales here. They are like many other also rands such as Black Widow who insist upon taking cheap off shore products and having them rebadged and brought to this continent.

All the little remotes with pathetic cartoon cars come from China, Tiawan, and Korea.

All of them perform pretty much the same way for the uninformed buyer.

If it's rice, someone will surely buy it. That is the mentality in this area.

Its all about the bling bling, and look at me. Opposed to real old style performance such as the ones from old school Clifford, Crimestoppers, etc.

Thanks for the replies guys.  Accept auex the self proclaimed "Certified Security Specialist" who seems to know a lot about nothing.  LOL.

Teken, very good info.  I'm thinking of enabling passive arming as I like the idea of the theif not geting the chance to scan anything when there's nothing being transmitted!  Just curious what your beef is with Compustar.  Is there some sort of major flaw or is it just personal preference?  I know some people complain of reliability but I have yet to have this problem and without a doubt this alarm has the best range I have ever seen on a 2-way.  I always thought that Spread Spectrum technology was much better than FM.  Am I missing something here?  Thanks.

Not sure what the big beef is about, probably just personal preference. I would like to add that Firstech may not be the maker's of the unit, but they are still having to input money into the added design of the initial units when first introduced. How much money is not known to the general public. Much like all the other electronic giants of North America, most of the manufacturing is done off shore over in Asia. If you want to put companies under the microscope, you can say that almost every part that makes up a CPU for an alarm or remote starter is made from Asia somewhere. It just depends on where it's assembled..... Canada, United States, Mexico, Japan, Korea or China is where the so called quality comes into play. In this day and age, the manufacturing quality that Asian countries are producing for the price they charge is far superior to what is made is North America hands down. That's why so many electronics are being made in Chine, Korea and Taiwan.

It's just too bad that they can make them work for a nickel a week or some crap like that, and not only do they put out a fairly decent product, they are thankful that someone has given them the opportunity to work for such a magnificent establishment.  What a crock!
