All-round review: TOP-5 two-channel video recorders
We independently test the products and technologies that we recommend.

It is proposed to familiarize yourself with the characteristics and prices of models from the selection in the comparative table of two-channel DVRs. The entire range of current offers of DVRs is collected in the catalog of the same name. And about the five well-downed video recording devices for adequate money are described in the article “I was right! And I can prove it! - TOP 5 good and inexpensive DVRs.
Video fixation devices in the format of a saloon rear-view mirror have found popularity among car owners due to their invisibility. The ins and outs of the Navitel MR250 camera is revealed only by the shiny "proboscis" of the lens, mounted on a movable base with a power reserve both vertically and horizontally.
The “eye” of the DVR looks at the road with a wide viewing angle - about 160 °. The image is transmitted through it to a 2-megapixel GC2023 sensor, after which it enters the reins of the productive MStar MSC8328 processor. In practice, the device provides high-quality video recording, as they say, day and night, recording videos on a microSD card in FullHD resolution (1920x1080 pixels).
Since the model is classified as a dual-channel recorder, of course, it has an additional reversing camera in its assets. The auxiliary "pod" can be safely mounted outside the car, since its body is protected from all kinds of external influences in accordance with the requirements of the IP65 standard. The second camera does not shine with high detailing of the frame, giving a picture at a resolution of 656x492 pixels, however, it manages to cover the rear with a solid "five". In parallel, the reversing camera can be used as a parking assistant.
A 5-inch IPS-screen with a resolution of 854x480 pixels is hidden behind the mirror part of the front panel of the head unit of the registrar. The mission to control the functions of the device is entrusted to the shoulders of the keypad on the bottom end of the case. Inside the model, there was also a piece of free space for a G-sensor, which is used to track sharp accelerations and decelerations of a car. In the event of an emergency situation on the road, the DVR will automatically save the recorded video at the time of the impact.
To be able to view the footage without connecting to the on-board vehicle network, the model is equipped with a built-in 400 mAh battery. On one charge of this, the recorder works autonomously for 15 minutes. As a bonus, along with the model, a one-year subscription to Navitel road maps is provided with a detailed drawing of streets in urban traffic conditions and truthful information about country roads in domestic realities.

What you will not find in the huge product fleet of the ambitious Chinese company Xiaomi. It is engaged in the production of everything and everything, incl. video recorders. Along with models of the classic format, the brand's portfolio includes a device that skillfully disguises itself as a rearview mirror - Xiaomi Yi Mirror Dash Cam.
The video fixation device is mounted on top of the regular interior mirror, harmoniously fitting into the interior of most cars. You can recognize in it something other than a regular rear-view mirror, except perhaps by the tip of the lens and the 4.3-inch touch screen at the head of the front panel. However, in the off state, the display remains completely invisible.
The mirror turns on automatically when the ignition key is turned. The video sequence on the main camera of the device is written in FullHD format (1920x1080 pixels) at 30 fps. With a similar frame rate, video recording is carried out on the auxiliary rear camera, with the only difference being that the maximum resolution of video recording of what is happening behind corresponds to the HD format (1280x720 pixels). In the daytime, the cameras do a solid job of rendering highly detailed images, and at night and in conditions of strong lighting changes , the WDR software dynamic range expansion function comes to the rescue in improving the quality of the video sequence.
In order not to stain the mirror surface of the recorder with traces of fingerprints, it is possible to get access to the settings of the car recorder from a mobile gadget by connecting to a video recording device via a Wi-Fi network. In addition, the wireless adapter is used to transfer footage and update the firmware of the recorder. Serious flaws in Xiaomi Yi Mirror Dash Cam are not observed, which is an additional plus in the karma of the model and explains the secret of its popularity.

The multifunctional "combine" PlayMe Omega combines a whole galaxy of advanced functions under one wing. The saying “And the Swiss, and the reaper, and the gambler on the pipe” is about him. Intrigued? Then let's understand the ins and outs of the model.
The car recorder makes video recording of the traffic situation through the windscreen, covers the rear, tracks the current location and determines the speed of movement using GPS satellites, and also warns of police ambushes with radars. Moreover, the device cannot be called a giant - the registrar turned out to be many times more compact than peers close in functionality.
Basically, the PlayMe Omega records videos in high resolution 2304x1296 pixels at 30 fps and with H.264 compression, which saves free space on the microSD card. The numbers of passing and oncoming cars remain readable with such data at distances over 20 m. The lens of the main camera looks around the world with a field of view angle of about 140 °, capturing the current lane of movement and one neighboring lane into the frame. The reversing camera shoots 720p video while assisting in reverse parking.
The head unit is equipped with a 3-inch screen and a push-button "command control panel". This is about the visible side of the issue. Hidden from prying eyes is a GPS module with an informer about exceeding the speed limit and the location of stationary video surveillance cameras. The built-in radar detector copes with the detection of unfamiliar cameras and mobile traps with a bang. With such a rich decoration behind it, PlayMe Omega will become a faithful companion for driving a car both in a big city and on country roads.
Automotive electronics under the Gazer brand name is familiar to many owners of “iron ends”. The key to the success of the company's products is the optimal balance of price and quality, no matter how trite it may sound.
One of the most advanced brand DVRs in the class is considered to be a model named F225. Structurally, the device consists of a command control center along with two miniature front and reversing cameras. They produce video recording in FullHD format with a frame rate of 30 fps and transmit data via separate channels. Processing signals from the cameras is occupied by a high-performance chip from the category of Ambarella A7L flagships. And everything would be fine, if not for the modest detailing of the captured video sequence - in reviews of the model, there are often complaints about the unreadability of license plates of other road users from a distance of more than 5-10 m.
Video recording is the main area of work for Gazer F225. But at the same time, the model is endowed with a lot of other useful functions. In particular, passive safety systems LDWS (lane control), FCWS (distance control) and LLWS (reminder to turn on the headlights). Moreover, when the device is additionally equipped with a GPS module (ACG225), the recorder warns in advance by voice about speed limits, bad roads, speed bumps, dangerous intersections and turns, pedestrian crossings, speed cameras, etc.
The recorder turns on when the engine is started and turns off as soon as the engine is turned off. In the parking lot, the command to start video recording is given by the motion sensor. A capacious 1100 mAh battery is used to power the device in the absence of voltage in the on-board car network. When "refueling" to the eyeballs, she can keep the DVR alive for more than an hour when shooting with two cameras at maximum resolution.

Every niche has top products. The ball in the category of dashcams is ruled by the Korean company BlackVue. Video recording devices from it are not cheap, however, they simply cannot be found equal to them in terms of the totality of data.
Model DR900S-2CH became the first chick in the domestic market, who is shooting in the "honest" format 4K at 30 fps. As a result, the detailing of the video sequence soared to unprecedented heights, and the license plates on the video remain distinguishable even from a great distance at night. The rear camera of the device captures the traffic situation in FullHD resolution with a viewing angle of about 139 °. She will have to look for worthy rivals not only among the auxiliary cameras, but also among the head video recording devices.
"Under the hood" BlackVue DR900S-2CH has a GPS module that deals with determining the current coordinates and speed of movement, and there is also a dual-band Wi-Fi adapter. By the forces of the latter, the auto-registrar communicates with gadgets from the outside "by air". The mobile application provides access to the video library and device settings, which, due to the lack of a display, is useful for the model.
The full potential of the DVR is revealed with the Over the Cloud kit, which provides the user with the ability to send files straight to the cloud. Unfortunately, you will need to buy it separately. The price of the kit, as well as the registrar itself, is the only stumbling block on the way to get the device to the store. However, in the absence of equals, even such a high price tag looks quite justified - you will not find worthy rivals for the BlackVue DR900S-2CH during the day with fire.
