Dash Cam

Anyone try using the Hero 3 HD as a dash cam? (See below)


Loop Recording
Loop recording is a new feature and is kind of mysterious at a first glance. Applications? You could use this as a car dash cam like all the people in Russia seem to have. Get a car USB adapter and keep the camera plugged in at all times. If you set it for, say, 20 minutes you’ll always be able to stop the camera and have at least the previous 20 minutes recorded. This way if on hour 16 of your road trip you see a meteor exploding, you can stop the camera and have 20 minutes leading up to the meteor explosion. Pretty cool. The way it works is by actually splitting the 20 minute duration by 4, and keeps 5 sets of these clips on the SD card at any given time. 4 of the 5 clips are 5 minutes in length (20/4) which equals the full 20 minutes, the 5th is the current one recording (until it hits 5 minutes). So if you stop after 44 minutes you’ll have 4 clips each 5 minutes long and one clip 4 minutes long. This is why I say you’ll always have at least 20 minutes (or whatever duration you set).

Go to YouTube and search for Techmoan for his reviews on dash cams. There are a lot cheaper options than a GoPro and you can get essentially the same quality in many regards if it is just for a dash cam that you seek. In the evening and at night or any low light condition, then the GoPro is a poor choice for a dash cam. Me, I'd be much more willing to pay far less for a dash cam than to risk some thief boosting my GoPro when it was left out in the car. The choice is your's to make though.

The cam you may want to get is called a keychain camera #16 version 2 cost $40.00 plus. You may want to hold off and wait for the #2 for at least a month or more told the #26 is available at what members quoted 60.00, where the sellers, developers are placing a 100.00 tab. on the Hd1080P model.

The gopro is the camera you want, purchasing the optional lcd pack and being able to set all the features on the fly, vs taking the 808 back home or having additional micro cards, and not knowing what is in the camera to change its settings....

You can swap lenses out on the 808, etc... you can hide the 808, and will cost you a lot less than a gopro.

No, I got it not just for a dash cam...but thanks for the replies...I was asking if anyone has used it yet for that...I use mine for that, along with other uses, but just found out what the looping was for after reading the article. If anyone else uses it for a dash cam, do you have any issues?

I suction cupped a Hero3 BE to the windshield in the middle of winter. Not sure if that kept it from overheating or not, which I've read overheating can be a problem.

I abhor cables running from the cigarette lighter outlet up to the windshield, so I put a battery pack on the top of the moon roof shade and ran a cable from it over to the camera over the passenger's side visor.

You must use a slightly discharged battery in the camera so that power is drawn from the battery pack. My battery pack turns off if not supplying power. The camera is aimed using Wi-Fi and the GoPro App on a iPhone or iPad and the camera is placed in looping mode.

Besides possibly overheating, there is no easy access to the date code and time stamp on GoPro video.

I would think dedicated dash cams would be less expensive and more convenient, including essential date code information in case of a recorded accident.

No I do not use my GPH2 as a dash cam, I do not display unless I am present?

I use a battery booster, so I know my car battery will not drain. over heating is not a problem, if you understand how your camera works

Good info...Thanks. And Yes, Dash Cams are much more economical for their stand alone purpose. But I travel many miles (hours behind the windshield) a year by car (Tacoma Truck). So having something versatile to pop onto the dash with a rubberized base (prevent sliding), and plug in quickly...and also quickly disconnecting and using it for my job and personal use. So this is a great cam for me.

My first time editing a clip using video pad for MacBook Pro.

I find the battery life to be lacking and not enough features to use it as a good dash cam. It's also too big. Look into blackvue if you want a real dashcam.

Here's an interesting article by autoblog:

If you've noticed a disturbing lack of dash cam in your life, our friends at sister site Translogic have just the thing for you. They've worked up a quick play-by-play for how to turn your GoPro Hero3 into a go-anywhere camera to record everything that goes on in front of your vehicle.

The steps are as simple as drilling small hole in the camera's water proof case to allow access to the USB charging port. From there, you can supply constant power through a 12-volt USB adapter. Mount the camera to your windshield using the suction mount and you're very nearly ready to go.

Next, set up the loop recording feature and you're good to go. The Hero3 can loop record in 5, 20, 60 or 120 minute files wherein it will record to the maximum time before starting a new save file. Once the memory card is full, it will record over the oldest file. It can also loop record in "maximum" mode, where the camera fills the memory card, then starts over again. Check out the video Translogic made below for a look at the finished results.
