Recording what goes on in front of your car is very useful, especially for capturing weird road incidents and the unfortunate collision.
But being able to record what goes on behind your car is just as important, since rear end collisions are just as bad – and actually harder to avoid, since you aren’t always going to be looking into the rear view mirror.
Additionally, when you have two cameras, you’ll cover a lot more area around your car in terms of video capturing, since the rear view lens is also usually wide angle.
Dash cam manufacturers have catered to this need and there are many models available that come in two parts – a front camera, which also houses the main “brains” of the camera, and a rear camera which is much smaller and transmits the video across a coax cable to the front camera.
Both cameras usually record in 1080p HD, but sometimes, the front camera will be full 1080p and the rear camera will be 720p.
All of the recording and storage is done in the front camera itself – so you can use the front camera as a standalone unit, too.
With a front-and-rear dash cam(also called 2 channel or dual channel dash cams), you’ll be covered for almost every situation possible.
Best eyewitness front and rear dashcams
Here are some of our favorites:
The Blackview DR750-LW is a two channel dash camera that records full 1080p HD video from both cameras. The front camera has a beautiful, sharp screen to view live video or play back recorded videos, and you can also use the companion Blackview app to view, edit, or even upload videos to YouTube directly. Your phone(Apple and Android) can connect to the camera through WiFi.
If you hook it up to your car battery using Power Magic Pro, you can use it as a CCTV and record when your car is off, too.
There is no GPS in this camera, but you can add it using an external attachment.
Like the Blackview DR750, the Blackview DR650 is a high-end dashcam that records both the front and rear of your car in beautiful 1080p HD. The DR650 does not have a screen like the DR750, so it is much sleeker. The cylindrical design lets you mount it in a way that it can’t easily be seen from the outside.
The lack of screen isn’t a huge tradeoff, since you can use the app to connect to the dashcam and configure it however you like.
The DR650 has GPS built in, and it will record the GPS data alongside the video, so when you retrieve the videos, you can retrieve the GPS data with it and display it on Google maps.
You can use Power Magic Pro with this camera as well to use it as a CCTV.
The Lukas LK-7950WD compares to the Blackview DR750. Both Blackview and Lukas are Korean brands, and are top quality and feel good to hold. The video quality is awesome, too.
The LK-7950WD has a front-and-rear camera. The front camera has a 135 degree wide-view and the rear camera has a 130 degree wide view. Both record at 30 frames per second in 1080p HD.
What’s really special about the 7950WD is that it has two memory cards – so you can set continuous recording on one card, and impact/event recording on the other card.
With the optional ODB-II interface, you can record your car’s speed, accelerator, and gear position data along with the GPS data.
The LK-7950WD has a lot more memory capacity than the Blackview cameras, too. It also supports parking mode like the Blackview cameras, and has wifi capability, too, with its own special Android and iOS app.
Lukas LK-9700 Duo
Fitted with a Sony Exmor sensor, the Lukas LK-9700 duo is an awesome 2 channel dash camera that lets you capture video from both the front and back of your car.
The LK-9700 is quite similar to the LK-7950WD, except the 9700 has a touch screen, while the 7950 has none.
Also, the LK-9700 rear camera records at 720p, while the LK-7950WD rear camera records at 1080p – so it’s a tradeoff, really.
Either you get a touch screen and lower rear camera resolution, or you get no screen and HD rear camera resolution!
To clarify, the resolution is only the size of the video – not how much area is covered. So both will have around 130 degrees of coverage, but one will have a larger video file, and the other will have a slightly smaller video file.
With the built in screen, you can also view the front and back footage as Picture in Picture, where one footage will be the main thing you see and the other footage will be a smaller box inside it. This is just for your viewing and not how it actually records.
The Lukas LK-9700 Duo comes in two models – B type and D type. With B type, GPS is built in. In D type, there is an external GPS module as well as an OBD module(like the one in the LK-7950WD).
