Transcend DrivePro 220M
The Transcend DrivePro 220m costs about 121 pounds / 140 euros, like the ASUS, and is a lot alike in terms of functionality. It has a built-in G-sensor and driving lane- and approach detection. The G-sensor is rather sensitive, even is the least sensitive mode. We tested the cameras in a car with stiff suspension, and with bumps the device registered an emergency situation all the time. Fortunately the G-sensor can be turned off if you find it annoying.
The DrivePro 220M has Wi-Fi as an extra function. This makes it possible to wirelessly pair the dash cam with a smartphone in order to change settings, view videos and copy them using a free application. Quite useful, because this way you will never need to remove the card – especially useful if you often want to move the images to other devices.
The DrivePro 220M is slightly more compact than the ASUS camera and also has the GPS module built-in, which looks better. The image quality of the DrivePro 220M is very good, although it does seems slightly soft and without contrast compared with some other cameras. The maximum resolution is 1920x1080 with 30 frames per second. The camera uses MPEG 4 AVC compression in an MP4 container, with a bit rate of about 15 Mbps. The only criticism when it comes to the image is that the camera slightly overexposes the image when using the standard setting. It can be remedied easily by changing the exposure compensation to -1. Once changed, the camera performs well, both during the day as well as in the dark. Night images are well lit, but if it is truly dark the image is slightly worse. Nevertheless the camera performs the best out of all the ones in the test; even in the dark.
