We have had a front facing dash cam for the last 6 or so months, but as of a few days ago me and my parents decided it would be good to also have a rear camera, which helps if an accident or interesting event takes place behind us. We ordered one and it arrived yesterday, and after installing it I thought it might be fun to write a little review about both the cameras to maybe help other users on this forum decide if they would like a dash cam, and which one they would like to buy.

Front cam: Black Box G1W-CB

The G1W (and most dash cameras for that matter) is produced in China, which means that copyright rules are very lenient and multiple different companies can produce the exact same product. Therefore, there are TONS of G1W's you can buy, some being great and others being awful. The Black Box is the highest quality and most reliable version I could find, and I still have had no problems with it. It is probably the most inexpensive camera out there that gives you a capacitor instead of a battery and 1080p30 video with a good bit rate. One inconvenience is that it will forget the date every time you restart the camera, which makes it hard to find a video clip you want. Luckily there is a save button on it that will put the 3 minute clip currently being recorded in a separate file folder, so you can find that event much easier. If you're on a budget and just need a camera that has all the basics, this one is a viable option.

Rear cam: DDpai mini

While this camera is intended as a front cam, it works fantastic in the rear. It has Wi-Fi, which allows for you to connect to it on your phone using the DDpai app, and you can save clips to your device instead of removing the SD card every time. The camera also comes with a wireless save button, which makes it extremely practical as a rear camera. However, the button will only take a 10 second video (5 before pressing and 5 after), but because it has Wi-Fi, it syncs the date and time with your phone which makes longer clips you may want to retrieve easier to find, especially in the user-friendly app. Video quality is fine for a rear cam; it still records 1080p but the bit rate is a bit lower and sound is very muffled. As a front cam (unless you're extremely hooked on having Wi-Fi in your camera) I would suggest the G1W over this one, but for the rear, I think it might be the most practical and best value out there!

Let me know if you have questions or would like any more details!

This is interesting, we are considering getting dashcams also

We have a BlackVue DR650GW.

It has Wi-Fi, which allows for us to watch ourselves driving along, live, on our phones.
We can download clips, etc.

Pretty good camera.

I'm going to buy a G1W after I learn to drive because I think it's something everybody should have. Nice setup!

Now that's a good setup!

I don't know if you have these in the States, but I use a Transcend DrivePro 200 up front. Like the G1W, it is not powered by a battery, so it's plugged into the 12V socket all the time, which should give you no worries about running out of juice. However, unlike the G1W, it does not forget the time and date when you turn it off. How cool is that ?

The DrivePro's camera combines an extra wide 160° viewing angle, resolution of 1920x1080p (30fps), and a row of 7 glass lenses to ensure your trip is recorded in high clarity. The DrivePro 200 includes wireless smartphone connectivity to let you stream, download, and share videos.

I should make a review of this if and when I have the time .

Here it is, in action:

I'm heavily considering getting a dashcam for my pickup truck. if the rear wheel drive causes an accident I want to be able to prove it was the rear wheel drive and not me.
