The VIPER alarm I got has a paging remote up to 1km away, If the car alarm is triggers or has given a warning chirp it will page my remote in my pocket and beep. I also had a microwave sensor added to the viper alarm kit usally used in convertables and an extra siren installed under the dash so it loud inside and out. The alarm cost about $900, maybe about $1200 installed with all the extras. To install it properly they need 1 1/2 days to 2 days to do the job proberly. I had to get it adjusted 3 times before they got the sensitivity right. Its the best alarm I've had so far. It also has AUX funtions like press 2 buttons and the stereo will turn on without the key. I can warm the car up without the key, but have to put the key in to drive off. The only downfall is every month or so I have to keep replacing the AAA battery in the remote. But hey its no big deal. This alrm also comes with a turbo time function, but I just use the HKS turbo timer as it has the auto time function. Also has a cool viper sticker on the inside of front windsreen that has a wire going to it and it flashes blue, very bright at night when the alarm is on. It looks coool.
