Why Do You Need a Car Digital Video Recorder?
A car recorder, also simply called a DVR, is a portable device designed to record and store events that occur in the field of view of its camera. This kind of video surveillance system allows you to evaluate various situations that arise both on the road and in the parking lot. The DVR’s media materials can often help the vehicle owner with controversial issues that may arise when communicating with police officers, analyzing car accident reasons, and in other cases.
The importance of a video recorder cannot be overestimated. Therefore, his choice must be taken very seriously. It is not enough for the device to just record any events. The key point is to make sure that the media materials can help restore important and tiny graphic details. You will be of little use in observing an emergency if the camera has a low resolution that does not allow you, for instance, to capture license plates with sufficient clarity.
How to Choose the Right Car Digital Video Recorder
When purchasing a DVR, you should focus on its technical specifications. The same manufacturing company can produce models that differ both in design and purpose, targeting a certain price range. It depends on what optical materials are used to manufacture the camera, the electronics performance, and additional equipment options.
The main thing when choosing the device is to understand what is required of it and to start from personal preferences when buying. The equipment will then be correctly chosen, and the consumer will be completely satisfied with its operation. Let’s take a closer look at the technical characteristics of DVRs that you need to pay close attention to when purchasing these gadgets.
Main Characteristics of a Car Digital Video Recorder
User preferences depend on the implementation of specific models, and it is necessary to choose a digital video recorder with the proper technical features because the best device is the one that meets the user’s requirements.
Camera and Lenses
The key elements of any CVR are special lenses. Their main characteristic is aperture, which determines the ability of the camera to work in low light conditions. Lenses for CVRs come with a fixed focal length and varifocal. Their main difference is the ability to change the viewing angle, which, as the name implies, is not available in lenses of the first type. At the same time, cameras with simple lenses are cheaper. Another advantage is their simplicity of design, which increases reliability.
In addition to technical features, cameras are usually characterized by the quality of recorded videos. The main parameter here is the resolution indicator, which shows how many pixels the recorded video stream has. The higher this value, the greater the clarity of the image can be obtained. When purchasing a recorder, it is best to choose cameras with Full HD (1920 x 1080) or HD (1280 x 720) resolution.
This characteristic refers to two different indicators. The first is the number of frames per second recorded by the device. This parameter is also called FPS. The standard value of the video stream frequency is 25–30 frames per second.
The second value of the write speed refers to copying the media to the memory card. It is identified by the properties of the drive, and for comfortable operation of the DVR, you should select a card of a certain speed class for its operation. With insufficient values of this characteristic, the video quality may decrease. As a result, some events simply will not be able to get to the drive, and given that at high speeds on the road, a lot happens in a fraction of a second, then critical moments will be missed by the DVR.
For the correct device operation, you can purchase SDHC 10 speed class memory cards. They provide stream recording with a frequency of 8 to 11 megabytes per second. This is quite enough for recording videos in Full HD.
For single-camera systems, it is best to choose a lens with a viewing angle of 120–140°, since such lenses allow you to capture what is happening not only in the frontal plane but also on the sides of the recorder. Smaller viewing angles are selected when there are multiple cameras.
It should be kept in mind that a large viewing angle implies significant image distortions compared to the perception of the human eye. Also, lenses with a large coverage area have a short focal length and visually distance the objects being shot. Therefore, the amount of detail at a wide angle will be less.
