Overview of the DVR Blackvue DR750LW-2CH
The Korean manufacturer http: //www.blackvue.co.kr/Prod/DR750LW-2CH.asp, drastically changed their marketing policy in order to oust the manufacturers of DVRs with a touch screen.

Now there is no need to purchase additional controller power type Power of Magic.
In the DVR provides the function of protection against discharge the battery in parking mode, when the minimum voltage 11,8/12/22,8/23,2B, which is selected in the menu.

Screen.
Almost all of the back surface of the DVR is a 4-inch touchscreen LCD display.

The physical size of the visible part of the screen is 87 x 53 mm.
On the screen there is no visible "pixelation", thanks to high resolution ppi screen.
DVR perfectly responds to touching the screen. It is almost instantaneous.
Any pressing accompanied by a sound signal.
The screen without jerks transmits video and natural colours.
A well-implemented features picture-in-picture to view video images from both cameras.

The screen is executed in the form of a square icon in the style of Windows 8.
A simple graphical interface allows any user to easily manage the entire system.
From all over the screen height of 5 mm is the top information line.
It displays the recording mode, working WiFi, microphone, the work of the speaker, the date and time.
On the main page of the screen, in the bottom row is a row with icons for quick control the DVR.
To change the settings, you can also use the program on the phone via WiFi.
WiFi
It is made on the basis of standards IEEE 802.11b/g/n with a maximum data transfer rate up to 150 Mbps in the range of 2.4 GHz.
With this feature, you can watch the video online, view and download a previously captured video on a smartphoneor tablet.
The range of links when you view real-time video I was in the range of 10-15m.
If not using WIFi function it automatically turns off after 10 minutes.
In real-time (Live View), you can play the video from the front and rear cameras, frame rate 20fps.
Copy video files via WiFi from the front camera to the smartphone is about 12-20 seconds.
The manufacturer has added a new feature to update the firmware via WiFi. It's called - FOTA.
Users can update the firmware without wires using the built-in Wi-Fi and applications at any time, without the hassle of downloading and installing from the PC.

The DVR can record video with a resolution of Full HD (1920 x 1080) @ 30fps on both cameras.

The angle of the anterior chamber is 146 gr. diagonally, 115 gr. horizontally, 85 gr. vertically.

Conclusions:
To control the DVR is convenient thanks to the intuitive icons on the screen, even in the presence of the Korean language. The screen works fast and responsive. Brightness you can adjust the screen by itself. Optimal angles and matrix Sony Exmor 2.4 Mpix make good videos, and cope with the difficult traffic conditions. Non machine readable well on both sides. The firmware you want to adjust and work with the white balance. Pixelization video is practically absent. Good speed of copying files over WiFi on the phone allows you to transfer video from the front camera for about 15 seconds. The manufacturer has added a new feature FOTA intended to update the firmware via WiFi. Convenient fastening allows in a matter of seconds to shoot video with the windshield.
The device is completely balanced and deserves attention.
