A 'black box' for your car -- just in case.
934366
This is the first dash cam I have owned.  I see videos on YouTube (mostly from Russia) of highway accidents, meteors, and other phenomena.  I think these cameras should be installed by manufacturers as a standard item (and they probably will some day).  It's like the 'black box' in airplanes; it's hidden and not really used unless there is a problem, and then it's invaluable.

This Thinkware cam installs with foam tape on a plastic mount.  You can easily remove the cam from the mount and unplug the mini USB connector if you want to remove it from the car.  The only place you can really install it is at the top-middle of the windshield, behind the rearview mirror.  The camera lens will only adjust a total 30 degrees or so, which will match what most windshield angles are so that you can point the lens horizontally.  Once it's installed and plugged into a 12V receptacle that shuts off when you shut off the car, it operates pretty much as a black box -- out of sight and (mostly) quietly.  It does announce "Continuous recording is enabled" after it boots up, but there may be a way to turn the sounds off.  The HD video is excellent and the wide-angle lens picks up almost the whole area of the front windshield.  The included 16GB micro SD card must be removed from the camera and mounted in a memory card adapter or the provided USB adapter to view video on your PC.  The video includes road speed, date/time, and GPS data of your route on a map (cool!).

A couple things I think could be improved:  1) The unit takes about a couple minutes to boot up and start recording once you start the car.  By that time, I have already driven to the end of my street... so any accidents that happened in those first few hundred feet would not be recorded.  2) I wish it came with at least 2 plastic mounts.  We have two cars, and it would be nice to be able to stick the mounts in both cars and then be able to switch the camera from one car to the other.  3) The camera records sound, but it seems very muted.  It might be important to clearly hear what is happening inside the car before/during an accident.  4) It would be nice to be able to either plug a USB cord into the camera to view video, or have a screen on the camera itself.

Before ordering this product, I think I read more than 70% of reviews (almost all 1-2 stars), and when I ordered it, I didn't expect it work, but it does what I expect (locking and unlocking doors, and I don't use trunk option so no idea about that). This is one product, but it seems when you buy it from different sellers you may get it at least in different packaging (if you read different reviews, you will find people takled about different packaging, and I don't know about their quality as I bought only one!). I bought from BrainyTrade and I am happy with that until now (4 months and still works). I have no relation with this seller, so feel free to select the one that you like more (maybe others are better I just don't know).

There are also alot of argues about its user guide and how much useless it is. To be honest, I couldn't find any guide better than this one!!! So simple that directly addresses what you need. There are 5 diagrams (A-E), and between B,C,and D, pick the one that it related to your car (most cars are negative trigger so Fig C works just fine and ignore the rest! You also need the diagram on top of the page) Bear in mind, you MUST know the electric system on your car and how to get to those wires. If you don't know your car's electric system, it doesn't matter which brand you buy, you need someone to install it.

One more point, this kit has a fuse like all other electric parts in your car, and the original fuse is 15A. Check your car's manual to see it is suitable for that or not (check your car's fuse size for power door lock/unlock), It is usually fine for 90% of cars, but sometimes you need to change it, as it was the case for my car.

Hope you have a good experience with this product

This is one of the convenient way to clear those ugly scratches around the car.

This is a solid little tool box. Well made and designed it will hold your equipment. I wouldnt classify it as a secure box other than a deterrent, it would be easy to break into by a determined criminal. But it works to keep you stuff together. I used mine as a trailer box for a 1/4 ton Jeep off road trailer that I am building. Its perfect.

They hide under the hood when not in use. Cheap and effective.

Its easy to use.  You only have to use the key to unlock it, unlike some of these devices where you need it to install as well.  The only reason I took away a star is that for me, I find the twin hooks to actually be a bit frustrating at times.  There are plenty of steering wheel positions where I cannot put the club on, and have it visible.  For me, the bright yellow color and the visibility are crucial in deterrence.  These things won't keep someone who really wants your vehicle from stealing it.  It basically says, "This one is going to be harder to take than another one just like it down the road, so why risk the extra time?"  Therefore, visibility is key, and you have to be conscious of your steering wheel position when  you turn off your car due to the extra hooks.

Appears to be an excellent product, well-priced, arrived quickly. I will put both in the glove compartment of my car...You never know! And, I like to be prepared for any eventuality.

I am attaching this with command strips to the inside middle console lid.  A product like this can save a life.  I drive a lot in the country, and I want to be prepared for an emergency.  I gave the second Car Safety Hammer to my husband.

Good for watching what's going on behind your car.  Good for checking "Blind Spots"  Don't let it lure you into false confidence and this is a handy addon.

Wanted to make it a little less appealing to anyone thinking about getting into my husbands 2008 F-350. We have had some vehicle theft in our small town and I wanted this to be another obstacle to over come. Ive heard that thieves can get past these deterents with-in seconds but its for our piece of mind too.

This requires Locksmith to plug in a laptop to your car to program it.  It worked the very first time.

This is a quick and easy solution to the lack of security around your valuable battery and engine parts, and to help keep thieves from trying to bypass your killswitch and force the engine to start.

Note that this particular model of lock is ONLY for the '97 TJ with the side-to-side hood release latch. It's pretty easy to install. Lift the hood and remove the top condenser seal (the rubber panel right before the radiator). Remove the two front screws for the hood latch. Make sure the hood lock is unlocked, then slip it between the grille bars and hold it in position under the screw holes. Pass the new screws down through the holes and into the top of the lock unit. Once it's tightened down, you should be able to turn the bolt and lock the hood latch in the secure position. Replace the top condenser seal, make sure the lock is unlocked, and close the hood before re-locking. That's it.

I was going to dock one star because I thought I found a way to quietly disable the lock. Turns out, I was wrong. However, if you purchase this lock, you will find a particular locknut on the backside that may worry you. Will a thief be able to remove the nut? Not likely, but you could always take a dremel and round-off the nut before installation to render it inaccessible. It would only take a moment, and would buy you further peace of mind.

Helps keep the honest people from accidently using your trailer or car.  You may still need a gun for the rest.

Despite having been told that this system would be compatible with a 2012 Civic, multiple auto mechanics partnered with Amazon (home/car service installation package) claimed otherwise. A number of them noted how the universal transponder bypass recommended by the manufacturer was severely outdated and a huge security risk (required stowing a transmitting fob inside the vehicle). Likewise, they also claimed that because the system required a key in the ignition to bypass modern start technology and also bypass the steering lock (regardless of whether or not you remove the lock beforehand), the chances of your battery simply draining or ruining other car technology was almost a guarantee.

Essentially, the product would only work as intended with non-immobilizer vehicles. Unfortunately, any vehicle that contains a security system with every security measure hidden within arm's length of the driver's seat.. is completely useless. Assuming a car burglar understands the installation process of a car installed with this product, it would take them 3 minutes or less to start your engine. Sure, the alarm system might go off for those three minutes if said burglar resorts to breaking a window or picking a door.. but how many burglars would care for the 3 minutes of noise if it guaranteed a steal?
