See everything! Five dual channel DVRs

Xiaomi 70mai Rearview Dash Cam Wide skillfully depicts a salon rearview mirror. Hidden installation allows you to secure the DVR from possible theft, plus there is no need to install the device before each trip and hide it when you arrive at your destination.

The DVR is “dressed” over the regular rear-view mirror using two silicone straps. When turned off, its ins and outs are given out by a small “proboscis” of a protruding lens with a visibility of about 130 °. However, it is almost invisible from the street. A noticeable difference between the model and colleagues in the car recorder workshop on the rearview mirror is an IPS screen in the entire area of the mirror panel with diagonal dimensions of as much as 9.35 inches.

Video recording is given to the registrar in a resolution of 1920x1080 pixels, both on the main and on the remote camera. The rear view unit can also be used for precise parking - the image from it is displayed on the mirror screen in real time. Also on board the model is a G-sensor that responds to shock and protects the video of these moments from being overwritten.

It is possible to set up the DVR or quickly transfer footage from it using a smartphone connected to the head unit via a Wi-Fi wireless network. The available settings in the model are at a minimum, especially for the remote camera. The main power supply to the Xiaomi 70mai Rearview Dash Cam Wide is from the car cigarette lighter socket, the backup is from the built-in 470 mAh battery. The availability of the model for a wide audience of car owners reinforces the positive impression.

The first products under the brand name 70mai, which is the "daughter" of Xiaomi, were released quite recently - in 2017. However, even in such a short time they managed to win the hearts of many motorists. Take, for example, the Dash Cam A800 Dual Channel DVR, an advanced device for 360-degree visibility around the car.

Xiaomi 70mai Dash Cam A800 is a potential bestseller. Judge for yourself, the head unit of the car recorder was armed “to the teeth” with advanced electronic “stuffing”, taught to shoot video in 4K, besides, the model is equipped with a remote rear-view camera with FullHD video resolution. The combination of the Sony Exmor IMX415 image sensor and a wide-angle lens with a field of view of about 140 ° is responsible for the quality of recording videos in front of the hood of the “iron horse”. It provides excellent readability of license plates of passing and oncoming cars at any time of the day and in inclement weather. Specially for night shooting, the device has a dynamic noise reduction function.

In addition, the head unit of the model has a built-in GPS module (it allows you to link the speed of movement and current coordinates to the video sequence), a Wi-Fi adapter for wireless pairing with smartphones, passive safety functions LDWS (line control) and FCWS (keeping distance). To operate the settings and view the captured videos in the cabin unit, a 3-inch screen is provided (without touch control support).

Power is supplied to the DVR from the cigarette lighter socket through a standard adapter with two USB sockets. In case of emergencies, emergency power supply of the device is provided from an on-board rechargeable battery with a capacity of 500 mAh. Video recording is performed cyclically on a microSD flash drive up to 128 GB inclusive. Those. when the space runs out, the camera overwrites old files. Important frames can be protected from being overwritten in the menu. In the balance, we have a well-charged DVR at an adequate cost.

One of the most important aspects when choosing a car recorder is the invisibility of the head unit. For this purpose, when creating a two-channel Neoline G-Tech X-53 model, they took an interesting step - they moved the entire electronic fraternity of the DVR components into a separate control unit.

The "brain" of the model is to be installed under the interior trim, and power is supplied to it directly from the battery. So it is better to entrust the installation of the head unit to specialists. A separate installation will be needed for cylindrical modules with front and reversing cameras, a cabin microphone, a panic button for manually marking emergency files, and a GPS / GLONASS antenna.

The model has a powerful Ambarella image processor. He has enough strength to simultaneously manage recordings from two cameras and save videos without dropping frames. The front camera of the recorder records video sequences in FullHD format (1920x1080 pixels at 30 fps), the rear camera records in HD resolution (1280x720 pixels). Relying on the data of the GPS module, information about the speed of the car and the coordinates of the trip are attached to the video files.

In the absence of a screen, all manipulations with the settings of the DVR are carried out from a smartphone via a Wi-Fi network. Also, from a mobile gadget, access to the footage is opened. The car recorder gives the user voice prompts, shoots to the clipboard in the parking lot (when the G-sensor is triggered, only a separate video lasting 8 seconds before the impact and 10 seconds after the accident is recorded), is equipped with a frost-resistant supercapacitor for backup power. The model deservedly is one of the most advanced means of video recording of road conditions in the market today.

Codenamed VREC-DZ700DC, this is Pioneer's flagship camera with remarkable video recording capabilities. And that's why.

The model consists of a head unit and a remote module for viewing the rear hemisphere of the car. Inside the front camera is an advanced Sony Exmor IMX307 sensor, supported by a 160° ultra-wide. Video filming on it is made in FullHD resolution (1920x1080 pixels) at 27.5 fps. For better visibility at night and in scenes with complex lighting changes (for example, when entering / leaving a car tunnel), the front camera has been brought in support for WDR dynamic range expansion technology.

The remote reversing camera unit is connected to the head unit of the car recorder with a 9-meter cable. Video recording is also carried out on it in FullHD format, and HDR technology is responsible for the wide dynamic range of the rear camera image. The picture from the cameras of the DVR can be displayed on the screen of the car's multimedia system through the video output on board the device.

Pioneer VREC-DZ700DC got hold of GPS and Wi-Fi modules, a swivel “peephole” of the front camera (it can be quickly turned from the road monitoring mode to the salon), and an advanced parking mode. In particular, when parking a car, the registrar monitors what is happening on an ongoing basis, but does not record everything on the memory card, but a 20-second video until the shock sensor is triggered and 20 seconds. after the incident. In general, both cameras of the model provide good resolution and sharpness, perfectly convey traffic features, markings and road signs.

When it comes to premium segment dashcams, the products of the South Korean brand BlackVue immediately come to mind. A vivid example of this is the DR750S-2CH all-round view model.

The device is produced in the corporate style of a compact cylinder, which does not block the view of the driver of the car and is especially invisible from the street. The front camera of the recorder is based on the advanced Sony Starvis image sensor and records Full HD video at a frame rate of 60 fps. A smaller cylinder is mounted on the rear window of the car and also shoots video in FullHD format (1920x1080 pixels).

In the absence of at least some kind of display , a smartphone or tablet with the BlackVue App installed ahead of time is suitable for the role of the command center for controlling the DVR. It provides an extended list of settings, a gallery with captured videos, video control functions and tracking the location of a car using GPS satellites are available. Also, through a mobile programme, you can send a voice message to the head unit of the registrar.

Video files from the device are recorded on a flash drive or can be sent to the "cloud". Interaction of the DVR with cloud services requires the optional Over the Cloud kit, which is purchased separately. What else captivates the model? At a minimum, high-quality night shooting and a supercapacitor in the backup power circuit. But the price tag of the auto-registrar cannot be called democratic. However, the high cost of the device is justified by really top-end weapons.
