What Are Car Alarm Sensors and How Do They Work?

METHODOLOGY

To determine the best aftermarket car alarms for your vehicle, we considered the products most accessible to the widest swath of consumers in the U.S. and compatible with the widest range of vehicles. At least one of our selections uses your vehicle’s OBD-II port, which means it will only work with post-1995 vehicles, but many other choices can be wired into older vehicles by a professional installer.
In considering the range of alarms, we specifically chose our picks based on available, performance (decibels, range, reliability), price and complexity of installation. Most of the more sophisticated modern car alarms require professional installation and may not be eligible for customer support without it, but they’re also the most effective deterrents. Our research also factored in a broad range of end-user ratings and evaluations by multiple testers.
METODOLOGIYA
Avtomobilingiz uchun eng yaxshi sotuvdan keyingi avtomobil signallarini aniqlash uchun biz AQShdagi iste'molchilarning eng keng doirasi uchun eng qulay va avtomobillarning eng keng assortimentiga mos mahsulotlarni ko'rib chiqdik. Bizning tanlovlarimizdan kamida bittasi avtomobilingizning OBD-II portidan foydalanadi, ya'ni u faqat 1995 yildan keyingi avtomobillar bilan ishlaydi, ammo boshqa ko'plab tanlovlar eski mashinalarga professional o'rnatuvchi tomonidan ulanishi mumkin.

Signallar assortimentini hisobga olgan holda, biz mavjud, ishlash (desibel, diapazon, ishonchlilik), narx va o'rnatishning murakkabligi asosida tanlovimizni tanladik. Murakkab zamonaviy avtomobil signallarining aksariyati professional o'rnatishni talab qiladi va ularsiz mijozlarni qo'llab-quvvatlash uchun mos bo'lmasligi mumkin, ammo ular eng samarali to'xtatuvchidir. Bizning tadqiqotimiz shuningdek, bir nechta testerlar tomonidan yakuniy foydalanuvchi reytinglari va baholashlarining keng doirasiga ta'sir qildi.

A car-crazy California kid, I’ve been writing and talking about vehicles for 25 years on TV and radio, in print and online, including AAA magazines in Arizona, Oklahoma, Northwest Ohio, South Dakota and the Mountain West, as well as BBC Autos. I serve as vice president of the Western Automotive Journalists, a professional group for automotive writers based in San Francisco, and have no relation to McKeel Hagerty of Hagerty Classic Insurance, who is younger, better looking and wealthier.

Mashinada aqldan ozgan Kaliforniya bolasi, men 25 yil davomida televidenie va radioda, bosma va onlaynda transport vositalari haqida, jumladan Arizona, Oklaxoma, Shimoli-g'arbiy Ogayo, Janubiy Dakota va Tog'-G'arbiy AAA jurnallarida yozaman va gapiraman. BBC Autos. Men San-Frantsiskoda joylashgan avtomobil yozuvchilari uchun professional guruh bo'lgan Western Automotive Jurnalistlari vitse-prezidenti bo'lib ishlayman va Hagerty Classic Insurance kompaniyasidan yoshroq, tashqi ko'rinishidan ko'ra va badavlatroq bo'lgan MakKeel Xagerti bilan hech qanday aloqasi yo'q.

The Carlock Second-Gen Advanced Real Time 4G Car Tracker and Alarm is easy to install, offers lots of features and it doesn’t cost much, so a win on a variety of fronts. From an install standpoint, it could hardly be easier. There’s only one piece and it plugs into your OBD-II diagnostics port. From there it relays your car’s status and location directly to your smartphone. Because it uses the internet and GPS, there’s no limit on range and at $50, it’s half the price of many simple two-way alarms. The only drawback is that there’s no active deterrent. The 4G doesn’t sound any alarms or flash any lights. If your vehicle does get stolen, it’s very helpful for tracking it down, but many security system shoppers would prefer to prevent a theft in the first place.

Carlock Second-Gen Advanced Real Time 4G Car Tracker va Signalni o'rnatish oson, juda ko'p funksiyalarni taklif etadi va u ko'p xarajat qilmaydi, shuning uchun turli jabhalarda g'alaba qozonadi. O'rnatish nuqtai nazaridan, bu osonroq bo'lishi mumkin emas. Faqat bitta bo'lak bor va u sizning OBD-II diagnostika portiga ulanadi. U yerdan avtomobilingiz holati va joylashuvini bevosita smartfoningizga uzatadi. Internet va GPS-dan foydalanganligi sababli, diapazonda hech qanday cheklov yo'q va $ 50 da, bu ko'plab oddiy ikki tomonlama signallarning yarmiga teng. Yagona kamchilik shundaki, faol to'xtatuvchi yo'q. 4G hech qanday signal bermaydi yoki hech qanday chiroqni o'chirmaydi. Agar sizning avtomobilingiz o'g'irlansa, uni kuzatib borish juda foydali, ammo xavfsizlik tizimining ko'plab xaridorlari birinchi navbatda o'g'irlikning oldini olishni afzal ko'rishadi.
