HOW TO CHOOSE A VIDEO RECORDER - which recorder is better to buy for a car

When thinking about which DVR to buy, first of all, focus on high-definition video. It is measured by the number of pixels across the width and height of the frame. The higher the resolution, the more detailed the picture is and the more little things in your favor you can see on it. For example, that the driver of the oncoming car was not just driving, but was fascinated by reading from the screen of his phone. As experienced drivers know, it is the one who has such facts that gets out of difficult situations.

Resolution Standards Symbols

• VGA - 640x480 pixels; an outdated standard with average picture quality, rarely found.

• HD - 1280x720 pixels; gives a picture of good quality, which can be "stretched" to the laptop screen.

• Full HD - 1920 x 1080 pixels; video of this resolution can be watched on a widescreen TV, looking for the smallest details.

• Super HD - 2304x1296 pixels; can be regarded as fashionable: it is good that it exists, but it does not give any special advantages over Full HD.

The quality of the shooting is also affected by the size of the camera matrix. If you have ever chosen a smartphone, then you probably know that cameras of "smart phones" are measured in tens of megapixels. In DVR cameras, this indicator is much more modest: a high-quality image is provided by devices with two or more megapixels on board.

The speed of the processor and the bit rate (the amount of information transmitted per second) are very important. DVRs with a low bit rate (up to 12 Mb / s) give a fuzzy picture on which you, not just a number, cannot determine the make of the car. A processor that is too weak will not be able to process the signal, so there will be pauses in the video for 1-5 seconds. Quite enough to skip most unusual traffic situations. Unfortunately, manufacturers rarely mention the processor in the descriptions of devices, so we recommend that you carry out its field testing at the time of purchase. Turn on the recorder and quickly turn around you several times: if there are no video freezes, the test is passed.

The next parameter is the horizontal viewing angle. There is a certain catch in it, which should be considered when choosing a DVR for a car. Everyday experience suggests that the larger the angle of view, the larger the section of the road will be captured by the camera. The logic is correct, but at viewing angles of more than 90 degrees, the so-called fish-eye effect appears, when objects at the edges are bent in an arc. Many Full HD DVRs will automatically shoot at less than 90 degrees of field of view, although the specified angle may be greater. An angle of 100 degrees is usually sufficient to capture the entire hood of the vehicle along with the side pillars.

“I've been driving for 29 years. Intense driving. Professional rights. I actually went on tractors for many years ... When dismantling, a general idea of ​​the accident is necessary. Not numbers. Still, situations often occur where it is necessary to find out who is right and who is wrong. A wide viewing angle will help with this. But reading the numbers of a runaway idiot is now a rarity. Besides, you won't read these numbers at night anyway. But there was a collision at night or not - you can not prove it from a narrow angle. "

What determines the duration of the shooting

The same dependence works here as with movies: the higher the quality of the shooting, the more space will be required to store the video. The longer the video, the more memory it will "eat". Therefore, never rely only on the built-in memory of the recorder and stock up on memory cards.Some devices allow you to connect flash cards or external hard drives to them via the USB connector.

Which DVR to choose also depends on its power supply method. If the device only runs on its own battery, it will not be suitable for long trips. For those who work behind the wheel, we definitely recommend buying a device with additional power from a cigarette lighter.

“All VRs (DVRs - F.ua's note) have a threshold for switching to a battery, and each is different. It looks like this (let's choose an approximate threshold of 3 volts):

1) the power is turned off - the threshold sharply crosses the 3-volt border and the battery turns on, the BP continues to work;

2) the engine starts and the voltage sags - 3.2 volts goes to BP, which is above the threshold; BP does not go to the battery, but this voltage is not enough for power supply and it freezes.

Conclusion: the threshold for switching to the battery must be higher than the VR performance from reduced power supply. "

Additional useful functions

Knowing the following nuances will help you put the final point on the question of how to choose the right DVR. The built-in GPS-navigator will be very useful if you have to restore the picture of the accident every minute. It can also be used to save the trip route to share with friends and colleagues.

Infrared illumination will allow you to remove the consequences of an accident at night, as well as fix the face of the inspector who stopped you on the night road. The same applies to LED backlighting.

As for the motion detector, this is a moot point. Newbies in the field of registrars often buy them with the hope of protecting themselves from parking thieves. However, experienced colleagues argue that it is much easier and more efficient to use a stationary camera aimed at a parking spot for this. Note that the detector and the motion sensor are different things: the motion sensor reacts only to the movement of the vehicle in which it is installed, and starts shooting when it starts.

“The recorder looks ahead and as soon as the question arose about turning it on when moving in the field of its“ vision ”, then the movement there is not constant, only occasionally (otherwise it’s easier not to turn it off at all). Then why do you expect a mysterious intruder to sneak up from the front? For example, the easiest way to hit the door of a neighboring car is from the side, where your independent registrar is "powerless" or he needs to put 3 more in the company (we do not count on attacks from above and below). Are you ready to watch hours of video at the end of the working day? Those. is it worth it? "
