Choosing a DVR: everything you need to know the buyer
Often, newcomers believe that a good DVR is the one on the packaging that contains the mysterious letters Full HD. However, this parameter can not always guarantee high quality of shooting. Due to the variety of settings, it is necessary to understand which characteristics are really important for the right choice.
Matrix
If you want a model with Full HD, then the matrix at 2.1 MP will be more than enough. Therefore, it does not always make sense to specifically select a 5-megapixel device, because this is not a guarantee of better quality than, for example, a 2 MP design.
And previously the 3 Mp matrix was considered a characteristic of professional devices. It is now with a variety of models began to produce improved models, but this is not a guarantee of better quality.
Processor
A quick response to tasks is one of the main conditions that consumers set themselves. This depends on the quality of shooting, and the stable functioning of the device.
For example, if you select a model with weak processor parameters, the DVR will write with loss of several seconds between several files.
Here, focus on the frequency - it will be enough 526 MHz, as well as the availability of improved shooting in poor lighting.
Optics
The standard option is plastic optics, which is present in most budget-class models. Modern DVRs are equipped with a system of glass lenses, the difference of which is in the improved quality of shooting under poor lighting.
Viewing Angle
This is an important indicator for getting a complete record of what is happening. From the angle of view depends on what area gets into the frame. This value can really become decisive for possible analysis of fraudulent actions.
But here there are some nuances. We will analyze on an example. In front of you, two completely identical models with a difference only in the viewing angles: one - 110 degrees diagonally, the second - 120 degrees vertically. In this case, it is better to give preference to the first option, since such devices are characterized by a higher degree of frame capture.
File media
In standard models, SD or microSD cards are used as the media carrier. Also, you need to pay attention to their class, the maximum is 10. There should be minimum class 4 cards that can work with FullHD resolution.
Professional models use a hard drive to store files.
Mounting
This is actually one of the important issues, since the DVR should be clearly fixed in the right place, so as not to degrade the quality of the survey. Here, take into account the nuance: the ability to rotate a 360-degree device if necessary will allow you to record everything that happens in the cabin, for example, a conversation with the traffic police.
In general, manufacturers use two types of fasteners: vacuum sucker and double-sided adhesive tape. The first option has less reliable parameters of fastening in winter, because in the cold it can become unstuck. It is recommended to choose models with two types of fastening.
Screen
The presence of the display allows not only to control the quality of recording, but also on the move to change settings, manage files. In the event of possible emergencies, you can immediately provide a record to the traffic police officer.
There are models that provide built-in Wi-Fi to display all files on your smartphone.
GPS System
The GPS module allows you to record information regarding the speed and acceleration of the route. It is possible to view your route with precise speed indicators. Good evidence in case of disputes.
Only taking into account all the characteristics in the complex, you can buy a DVR in Odessa, Kharkov, Kiev with delivery to Ukraine, with high quality recording and reliable work.
