For those who prefer to have a car alarm that\u2019s a bit more sophisticated compared to what\u2019s available in the market, the Crimestopper SP 502 car alarm is a pretty advanced option to consider, as it pulls all the stops to keep your car safe and secure. The security system allows for keyless entry, is able to remote start your engine, and comes with an LCD remote that allows for two way data transmission between it and your car. It\u2019s also got a 20 Watt single tone siren, and a starter kill output as an added security measure that can completely disable vehicle operation. Go ahead with this review to find out if it's the best car alarm for you.\r\n\r\nWhy We Like It - Crimestopper SP-502 2-Way review\r\nThe Crimestopper two way LCD paging combo alarm is a reliable solution that should allow you to worry less about the safety of your car. It comes with a single tone siren, a dual shock sensor and a single alarm keyless entry feature so that you don\u2019t have to lock or unlock your car through the door lock all the time.\r\n\r\nPerformance\r\nIn many ways, the two way rechargeable LCD remote that comes with this Crimestopper remote start system is a highlight that many people will come to appreciate. Being a two way LCD transmitter, the rechargeable remote is able to relay visual confirmations of functions such as trunk release and arm\/disarm, and because its companion transmitter doesn\u2019t have the same LCD screen, you\u2019re going to need to take good care of the two way LCD security paging remote and keep it from getting lost. In this aspect, it\u2019s better than the viper 350 plus 3105v 1-way car alarm since none of its keys come with an LCD screen. Along with this security system, you also get a dual stage shock sensor installed in your car, so that it only sounds the siren whenever there\u2019s considerable interference with the car.\r\nDesign\r\nThe Crimestopper two way LCD paging combo works great especially for users who value their car a lot and always want to know about how secure it is. It\u2019s screen keeps you up to date on the status of the car, and with the 3 auxiliary outputs that the system includes, you\u2019ll be able to hook up other accessories to the system to be able to control them from the car\u2019s remote. If you\u2019re looking for a cheaper option that will still work OK, then you should check out the avital 3100LX car alarm.\r\nValue\r\nWith the two way LCD remote of the Crimestopper being able to work from a distance of up to 3000 ft, you\u2019ll be able to use its remote start combo feature to pre-warm or pre-cool your car, and with its starter kill output, you\u2019ll be assured that no one else is able to gain entry into it as well. The two way paging remote is also not limited to just one car. You can have the combo alarm keyless entry system installed in two cars, and if you\u2019re going to be doing this by yourself make sure you go through the product information section of the manual so that you know exactly what you\u2019re dealing with. Despite all these good features, the Crimestopper SP-502 doesn not come with a GPS tracking system. The carlock 2nd gen advanced real time 3g car tracker would be a great option to go for if that\u2019s something you can\u2019t do without.\r\nCrimestopper SP-502 2-Way review Wrap Up\r\nThe two way paging combo alarm keyless entry Crimestopper alarm is a great pick for anybody that\u2019s looking for peace of mind whenever they park their car somewhere.
