#Car DVRs
Car DVRs.
Nowadays, few people doubt the need to have an electronic witness in their car.
The practice of «setting up» on the roads, illegal actions of traffic police officers, when you are charged with violations that you did not commit, accidents in which the culprit is often determined by the one who quickly invited «witnesses» or agreed with the inspector have become a common occurrence.
An ordinary person who has been in an accident does not always succeed in using the recordings of surveillance cameras that are already installed at some intersections.
It remains to choose a car recorder that suits you.
According to user surveys, the requirements for recorders vary quite a lot. The first question is the camera viewing angle.
In order to capture two traffic lanes and have a fairly detailed image, it is enough to have a camera with an angle of 60 degrees.
Many people want to have a viewing angle of 120 degrees so that they can record «cutting», but in this case the image will be so small that it is quite difficult to record the color of the traffic light and the license plates of nearby cars.
They get out of this situation by installing two forward-looking cameras with a viewing angle of 40-78 degrees.
Recording from the rear camera can also sometimes be necessary, but such cases are very rare.
Many insist on recording sound to record conversations, but in reality no traffic police officer will talk to you in your car.
Well, most consumers rightly demand cyclic recording from the recorder with erasure of previously recorded information, so that there is no need to check whether the device's memory has been exhausted.
Recorder are now being produced that can meet any requirements, the question is in price and size.
The simplest video recorders such as DV-001 or DV-011 cost from 2 to 3 thousand rubles, have one 60 g camera, cyclic recording on an SD card, and are powered by a cigarette lighter.
Cons — low recording quality, no display.
These are video recorders for the most unpretentious users.
A higher quality recorder of this type is DV-006 or Sova, it also does not have a display, but has good recording quality 640 * 480 in a cycle on an SD card up to 16 GB, has IR illumination and a video output for viewing information on the display.
They are convenient to use together with a car radio or navigator with a video input and in my opinion this is a very good option for a budget DVR.
More convenient are recorders with a display for viewing the recording on the spot. This is Vosonic GV6330, it is made in a waterproof case and in addition to the car mount has a mount for the motorcycle handlebar.
For those who want to have FullHD quality video with the ability to distinguish car numbers at 10?20 meters, there are the Carcam Q2 and F500HD models.
These DVRs differ only in firmware and camera viewing angle. The F500HD has a narrower angle, and the Karkam Q2 has a backup function.
A more popular car DVR with a display has appeared now — this is HD 720P or DVR 007, it has a low price, a folding display, which makes it more invisible, and very good resolution.
Among professional car DVRs with installation and output of cameras, ASV-RF03M is popular. This is a multifunctional DVR with recording on one (25 fps) or two (6 fps) cameras, recording in a cycle and by motion, vibration and frost-resistant.
The recording quality is very decent. Now ASV-RF 03auto with a high-quality camera in the kit and a version with two cameras in the kit are produced.
Also ASV RF 03 GSM with two and four video inputs with the ability to transmit images over GSM networks. For those who need an audio channel, DVR 1T with one video channel 25 fps and an audio channel, recording on an SF card up to 32 Gig.
For those who want to be completely secure and install several cameras, CF-DVR or DVR 4T. This video recorder records images from four surveillance cameras at a speed of 50 fps per stream and one audio channel on an SF card up to 32 Gig, recording in a cycle and by motion.
There is an output to the monitor for viewing. The disadvantage of such video recorders is the need for installation work in the car.
There are 4-channel vibration-resistant car DVRs on a hard drive with a more professional interface BestDVR 403mobile, FUHO 4030 mobile, but their size will not fit any passenger car and they cost about 14-15,000 without a disk.
We recommend installing cameras for car DVRs if they are color, then day/night, at least 420 TVL, for example CM 3120, for installation at the back, a SLR camera such as RC-07C is required.
Many people use a laptop with a WEB camera or a regular camera through a converter such as 601WD, but in my opinion it is not very convenient to carry a laptop with you, always turn it on and configure it.
For a motorcycle, you can use a sports video recorder with a mount on the steering wheel DVR 648, it is sold complete with a set of mounts.
It has good recording quality, as a disadvantage is the lack of cyclic recording.
In my opinion, the most convenient solution is a video recorder in the rearview mirror. They are currently available in two versions DVR 321 in a wide panoramic mirror and ZR-738.
DVR 321 has a camera with a 90 degree angle, records 25 fps with a resolution of 640 * 480, a screen for viewing 3».
A new version with better quality is now on sale.
Very convenient: turn on the power and the recording starts, turn it off and it stops, in addition, there is a second video input for connecting a rear view camera.
The mirror is quite high quality and you can view the recordings at any time.
The whole installation is to put it on the standard mirror, connect it to the cigarette lighter and point the camera. The ZR-738 has a 70g camera, records 25 fps, resolution up to 640*480, 3.6” screen for viewing, and a rear view camera is included.
They are convenient because they are enough to install them on the standard mirror and turn them on, the recording will go in a circle, if necessary, you can show the image on the spot, if you need to print still frames, this can be done on the computer.
The disadvantage of the 738 is the need to manually turn off the recording when you park the car and, as it turned out, when working, it significantly weakens the GPS signal.
Nowadays, video recorders with a GPS module and shock sensors are popular. This is a video recorder with two wide-angle high-quality cameras with a video output for setting up the Safe Box 120 camera.
The wide-angle camera, directed into the interior, allows you to see not only the entire interior, but also the immediate surroundings of the car through the side and rear windows.
The disadvantage of this device is the ability to view recordings only through a PC.
The VD-3000 device is free of this disadvantage, which is equipped with a 2.4 «color monitor on which you can view and display recordings on the spot.
But in addition to this, the PC can view shock sensor records and the route on the Google map.
The new VIEW-i Golg device has the same functions as the SafeBox 120, but also a video output for viewing video recordings on the monitor.
The JS-300 video recorder also has a GPS sensor and a built-in camera.
Instead of a second camera, it has video input, which allows you to install a second camera in any convenient place in the car.
Video output allows you to view recordings from both cameras.
