You can buy a DVR for modest money, and there are really a lot of settings even on the simplest devices. Healthy Food Near Me and Artur Makeev, an employee of a car service, understand the intricacies of the operating modes of car DVRs.
Conceptually, the recording mode in modern DVRs can work in two versions – cyclical и continuous.
What is DVR Loop Recording?
During loop recording, the recorder captures and saves files in short intervals from 1 to 15 minutes. This is done in order to save space on the memory card – if necessary, the device itself deletes the oldest entry from the drive, and all the latest ones remain intact. Also, when the recorder is recording cyclically, it is more convenient to navigate when working with video later. It is easier for the user to download the desired segment of a couple of minutes than to look for the moment in the recording of a many-hour trip.
But cyclic recording also has one feature – at the moment of switching between recording segments, the device may “lose” part of the video. This is the sin of very cheap devices with weak electronic “stuffing”.
What is Dash Cam Continuous Recording?
With continuous recording, the DVR will work as long as the power is connected. Thus, in one trip, the device can shoot hundreds of gigabytes of video – everything is limited only by the amount of available memory. This mode is more convenient for those who save trip records to a capacious memory card or directly to a hard drive.
Why do you need a permanent record on the DVR?
As we said above, during continuous recording, the DVR does not divide the recording into several parts. Accordingly, because of this, some frames simply cannot physically disappear from the video. The continuous recording mode is used in order to be sure of the usefulness of the recorded video.
Setting up the DVR for continuous recording
There are many models of DVRs, but in general, the setup always remains the same. In the device menu, select “Settings”, and then “Operation mode” or “Recording mode”. Normally, you can select either the cyclic or continuous recording mode of the DVR here.
We will immediately warn you that the round-the-clock operation of the DVR is theoretically fraught with a complete discharge of the battery. We will assume that in the operating mode the device consumes about 0,5 a / h. In passenger cars, batteries of 60-70 a / h are usually used. Thus, hypothetically, the recorder can fully discharge a full battery in ~ 120-140 hours of operation. With the advent of cold weather, the situation can only worsen.
But modern models of recorders, as a rule, after turning off the engine, can go into “sleep mode” and start recording only at the moment when someone passes by or the car is hit. In this mode of operation, they consume almost no energy, but you can’t call it a round-the-clock recording.
Switching power in the car for round-the-clock operation of the DVR
Consider a few examples of power switching in a car for round-the-clock operation of the DVR in the cabin. The recorder will work in this mode even when the engine is off.
So, the easiest option would be to connect to the car’s cigarette lighter. In this case, the socket will be constantly occupied, but you can buy an adapter for several devices. The main thing is not to choose a very cheap one.
Another logical option for 15/XNUMX recording is to connect directly to the battery, bypassing everything else. To do this, you need to lead the positive power wire of the registrar to the positive terminal of the battery itself, and connect the negative wire to the metal part of the machine body. A XNUMXA fuse must be connected to the circuit that feeds the DVR. Also, it will not be superfluous to bring a button into the interior of the car, which will turn off the power of the recorder from the battery if necessary. It must be inserted into the gap of the positive wire.
Selecting a memory card for permanent recording
The choice of memory card size depends on the model of the DVR – some cannot work with cards larger than 128 gigabytes. For continuous recording, you need to choose a card with the maximum possible volume, since on average one minute of recording in Full HD takes about 100 megabytes of space.
It is also worth considering the speed of writing to a memory card, it must pass through class 10 or Ultra-High Speed.
