Premium Security and Remote Start - SP-502

The SecurityPlus SP-502 alarm system is a high-tech 2-Way paging security system that will provide a high level of protection for your vehicle. This system includes a 2-Way Rechargeable LCD pager which will alert you of any kind of intrusion or vandalism at the vehicle. The system includes the latest in vehicle security technology such as a dual-stage shock sensor, starter kill output, and a 25W high-power single-tone siren. The interactive display on the paging remote confirms all commands almost instantly with easy-to-understand icons. It alerts the user to alarm triggers by beeping and vibrating when out of audible range of the siren. The LCD screen will also turn red when an alarm trigger is reported to the user.

Remote Start

Allows a vehicle's engine to activate without physical contact from the user. This feature is useful for warming up your vehicle's engine and transmission to operational temperatures. In cold climates, you can have your interior hot or in warm climates, you can cool it down before use. All of this can be done while in the comfort of your home or office.

LCD Remote

Receive visual confirmations from your vehicle's security system or remote start system. Features such as remote start, lock/unlock, arm/disarm and trunk release will appear on the remote’s screen with its current status. An LCD remote can display warning icons when the doors, trunk or hood are open. If your vehicle is tampered with, some remotes display what part of the vehicle was affected.

Keyless Entry

Performs lock and unlock tasks without physical contact with the vehicle. Power door locks can be controlled from several feet away or even within a building using a remote fob. The fob emits a radio frequency that is digitally encoded to prevent frequency stealing so no one can enter your vehicle without your wireless transmitter.

Dual Zone Shock Sensor

This shock sensor utilizes warning chirps for minor disturbances and will trip the alarm if it detects more serious impacts or disruptions. Most dual zone shock sensors have adjustable sensitivity to reduce false alarms or warnings. These sensors let would-be thieves know that your vehicle is equipped with an advanced alarm system and to keep away.

Dedicated Trunk Release

This unit comes with trunk release capability and remote control integration for OEM alarm or add-on trunk release systems. Pop your trunk using your remote transmitter for convenience and ease of use. Carrying a handful of groceries? Arms tied up with luggage? Pop the trunk without using your key so it’s open and waiting for you when you arrive.

2-Way Paging

Send commands to your remote start or alarm system and receive confirmation that those commands were carried out. Obtain updates on your vehicle's security status and get driver pages on the remote. If your vehicle is being tampered with, your remote transmitter will warn you and set off the vehicle's alarm.

$99.00 + free shipping; I’ve paid $300.00 for less!

Does everything a much more expensive alarm does. Kill, code hopping, auto start etc... installed in a few hours with no problems. Wires are long, no need to splice extensions. Remotes (1) display (1) standard are solid and handsome and receive/send long distance. Couldn’t be happier with this purchase! Ordered on a Sunday afternoon and received the package in perfect condition (complete) on Thursday. If you are in the market for a great alarm at a bargain price this is it; you won’t be dissatisfied.

Bang for the buck

Can't beat it for the price. Install wasn't too hard, had to figure out the hot lead but other than that it went pretty smooth. Two way remote is awesome even if the touch screen is a little sensitive,( careful when you put it in your pocket ).

excellent buy

I am very happy with this purchase, install was a breeze considering all of the functions that are available with this alarm. It works great and has tons of features. I have purchased more expensive alarm systems that didn't come close to this one! Remote start and paging have an amazing range and with flawlessly. I have a little bit of experience with installing car electronics; and this went in pretty easy.
