CARLOCK Anti Theft Car Device - Real Time 4G Car Tracker & Car Alarm System. Comes with Device & Phone App. Tracks Your Car in Real Time & Notifies You Immediately of Suspicious Behavior.OBD Plug&Play

I have a lot of experience with GPS car alarms. I've been running the 103B china models in two of my cars for 10 years. The negatives of them is they need cell phone plans, they pull a decent amount of power (30mA) which made my car batteries only last about 2 years, and the signal strength wasn't very good.I decided to switch to Carlock after good reviews from my friend. Overall I am very impressed. It has amazing service, even inside my garage. I love how it shows the vehicle battery voltage and will even alerts you if it drops too low. The power draw is very small at just 2mA. That's 15x less than my old alarm systems. The vibration sensor seems to have a good degree of sensitivity. It's not to sensitive, but also triggers my phone app within about 2 seconds when I open one of my doors.The one negative is the Tag to automatically arm/disarm the alarm. It appears to activate on motion (such as when you are walking). It does arm and disarm my car every time. The main issues I have probably wont affect most people. For the car I drive to work, I like to take lunch break in my car. As I'm sitting there listening to music, it will arm again. Occasionally since it's armed the vibration sensor sends me an alert from the music bass. I wish it was a little better at checking if it's near the car before it arms again. I'll get half a dozen alerts or more in just one 30 minute lunch break. I bought my seconds alarm for my show car. I'm probably not going to use the smart lock feature with the tag because it will most likely keep arming when I'm sitting by my car, then disarm if I stand up to talk to someone. Maybe that will change in future updates.Overall I'm very happy with it. It's great peace of mind knowing where my cars are at all time and if one gets hit in the parking lot or broken into, I'll know immediately.

I was in the market for getting a GPS Tracker with an alarm. I am old school, I was looking for an alarm that sounds loud and everyone can hear it. This is NEW technology, when you buy the (motion sensors ) extra. They go off as soon as the car detects any movement and the APP on your phone goes OFF LOUD. There is no excuse I did not hear the alarm. At the car there won't be any sounds. This is good because the person messing with your car will not know. Giving you time to act in which ever way you decide is safe for you.The app gives you GPS TRACKING depending on the subscription you purchase. The subscriptions are the most reasonable on the market at this moment. It also lets you set an alarm at any top speed you want. Anyone driving the car goes over that speed the alarm will go off on the APP on your cell phone. It also rates the way you drove your trip letting you know where you were speeding and where you did hard stops. The app also shows you how many miles you have driven on a monthly basis in case you want to keep track of your milage. Trips you have taken and length in time of each trip. Many more features, I just want to give you an idea on what you will get with this unit.As far as the Unit I purchased the OBDII extender and placed the unit away from my OBDII. No one knows I have the unit installed except me. Plus it leaves the OBDII open for any time you might need to access it. This unit also activates the alarm on a timer. The app lets you set up the time you want the unit to activate after you have turned off the car.I purchased the unit I also purchased sensors for each door of my vehicle as well as the tag. The TAG is one of the greatest add on I highly recommend. What the tag does is activates and deactivates the alarm automatically when you come close to your car automatically. This way you won't have to do it with your cell phone before you open your car.All in all if you want something that will not break the bank and will give you a piece of mind I will highly recommend this unit. The only thing is that in order to make this GPS ALARM work the way it is intended to don't SKIMP out on the add-ons. Buy the add ons you need because you will save on the monthly subscription and have a piece of mind. How much is a piece of mind worth it to you?Item I would highly recommend and I am not part in any way with this company. All I am is part of the CARLOCK Family.

Carlock is the most amazing device GPS locating you can locate just about anything as long as you have a OBD connection in your vehicle or toy or machinery. The design is incomparable. They have different plans for as much protection as you want but I go for the $9.99 cent standard subscription per month and believe me it is so worth it to know where your vehicle is 24/7 365 days out of the year. It's super easy to use and they have great features too. Such as notifications if you're driving too hard or driving crazy it will notify you to slow down don't break so hard. Most of all don't drive crazy you can set the miles per hour to what you're comfortable with mine set to 80 Maximum speed. That's on the freeway of course. The Carlock actually helps you not get tickets. And drive safer whoever's driving the vehicle you can monitor your kids driving your car or truck. Or if you have the mobile Carlock you can have it on a piece of your machinery and find out where it is at all times a case to get stolen such as a cement mixer I personally will always have this app no need for a LoJack You can monitor several vehicles at 1 time inside the app. I recommend this app to all of my friends and family you can't beat it and for the low low price Carlock is unbearable by any other GPS car, vehicle Or machinery Location finder I love car lock and wouldn't trade it for anythingTake my word for it it will be so worth your time and money to invest in such a small device an application for $10 fee per month subscription I love you Carlock you're the greatest!Paul Angel 🚘👼🎸
