General Features

Remote Start
If the alarm or remote start module has "Yes" for this value then the system has an electronic device that allows you to start your vehicle by remote control without actually being inside the vehicle or using the key. The remote start system supplies the vehicle with power and simulates a start just as if you were inside using the key. Select vehicles require additional accessories or immobilizer/bypass modules to use the remote start feature.
Keyless Entry
Keyless entry allows you to remotely lock, unlock, and open the trunk of a vehicle if that is equipped with power door lock motors (actuators) and power truck motor (solenoid). Door lock controls via the remote are found on nearly all of today's car alarms.
2-way Paging
Alarms with 2-way paging inform the user via remote vibrating/audible/visual alert when the alarm is triggered. The pager must be within range to receive the transmitted signal.
Number of Remotes
The number of remotes included with the alarm system purchase.
Number of Buttons on Primary Remote
The amount of buttons on the Primary Remote generally equals the number of functions that you can use your remote for. Some remotes have auxiliary buttons which can perform more than one task per button.
Main Transmitter Type
LCD and OLED transmitters display various screen savers, warnings, alerts and other features on the face of the remote, rather than first generation button-only transmitters. They provide more information typically and other features.
Sidekick Remote Transmitter Type
Some car alarms and remote start systems come with more than 1 transmitter, which is referred to as the "sidekick" transmitter. Most LCD/OLED systems come with a button-only sidekick transmitter, while select units come with an additional LCD/OLED transmitter.
Optional (Accessory required and sold separately)
LED/Display Color
The color of the LED indicator(s) on various items such as button-only car alarm transmitters, various chargers, cell phone accessories and other products.

For OLED or LCD car alarm remotes/transmitters the display color refers to the color(s) of the screen.
Multiple Color with Animation

1 Mile
Number of Car Alarm Channels
The total number of channels that the car alarm system supports. These channels can include locking and unlocking doors, opening the trunk, remote start, and many other options.
Most car alarms come with a siren that can be installed. The siren will sound when the car alarm is triggered the alarm goes off.
Shock Sensor
The shock sensor is designed to trigger an alarm on light or heavy impacts and vibrations (standard sensor included with most alarms).

A dual zone shock sensor is a feature of proximity and shock sensors only. Zone 1 ( light impact on shock sensor and short motions(adjustable) on proximity sensor) will trigger warn away chirp to warn intruder that car has an alarm without setting off the full alarm. Zone 2 (heavy impact on shock sensor and extended motions(adjustable) on proximity sensor) will trigger the alarm to “go off”.


Two-Way Paging Features

Interior Thermometer
Some of the higher end car alarm systems are able to detect the temperature of the cabin. The temperature can then be displayed on the remote.

Remote Start Features

Cold Start Timer
Great for those on a set schedule who need their vehicle to warm up at a specific time every morning for example.
Turbo Timer
Some remote start systems have turbo timer feature which allows the vehicle to run for a specified amount of time after exiting vehicle. In turbocharged vehicles this prevents hot oil in the engine from choking up in the lines. Hard driving can raise engine oil temperatures to dangerously high levels. Proper cool down is essential for a healthy turbo and engine.

Awesome Alarm System

December 15, 2010

Great range and ease of use. I installed this system about a year ago to replace a really bad Scytek unit. This alarm has had no issues with range, false alarms or not recognizing the remote like the previous system. The remote start works flawlessly and remote battery lasts about 2 weeks before recharge via USB.. I have it on a 2008 Chevy Express 2500 HD Diesel van.

This is one great product i plan on purchasing ever since i saw it at my local audio shop. I love the features it has, if your car is about to get towed it has a tilt feature to let you know your car is being messed with.
