Disputes often arise after a car accident. To solve them it is necessary to have the complete details of what happened. Dash cams are becoming more and more common nowadays. The information they record can be provided as evidence by insurance companies. Find out what are the characteristics of a good dash cam.
8 ESSENTIAL FEATURES
The resolution. This refers to the number of pixels determined by the width and height of the image. It is something that directly affects the quality of the video. Higher resolution means a more detailed image. For example, this will allow you to see the driver of the oncoming vehicle and to know what distracted them while driving. Currently, the following resolution standards are found:
vga. 640 x 480 pixels. It is an obsolete standard that is not often used today, it provides an average image quality.
1280 x 720 pixels. It allows a higher quality image that can be enlarged to the size of a laptop screen without losing quality. However, some pieces, such as the license plate of the car, cannot be seen completely.
FullHD. 1,920 x 1,080 pixels. This standard video size allows you to see fine details on a wide TV screen.
SuperHD. 2304×1296 pixels. The image is 1.5 times sharper than Full HD.
Bit rate. The definition of the image also depends on the bit rate (the number of information transmitted per second). If it is below 12 Mbs, you will not be able to see details such as the license plate number or the car model. Also, low CPU speed can cause the video to pause for up to 5 seconds, so you might miss some important moments.10 Best Dash Cams
Sensor size and number of megapixels. A larger sensor means better video quality. The sensitivity of a sensor depends on its size, something of great importance when recording in low light conditions. A sensor between 3 and 5 Mp is enough to record video in Full HD. Buying a camera with more megapixels will not be a good idea, since its features will not be able to be used.
Vision angle. The wider this angle, the larger the scene captured by the camera. However, an extremely wide viewing angle will create distortion. For optimal vision, a value between 100 and 130° will suffice.
Number of lenses. Single-lens dash cams record only the road ahead. That is why it is better to buy dash cams with sockets for auxiliary lenses, three of them being the best. Thus, you can record the events from all sides.
Power supply. Battery powered dash cams are not good for long drives. Buy the dash cam with a cigarette lighter adapter if you spend a lot of time in the car.
Mount Type The dash cam can be attached to the windshield using a suction cup or double-sided tape. The suction cup is quite large but can be reused. Adhesive tape, on the other hand, is for single use. The dash cam can be attached to the mount with an inexpensive threaded joint or with a magnet, which is more expensive and easier to use.
iMost modern DVRs are equipped with a G-shock sensor, which captures the moment of impact. When activated, the camera saves images a couple of seconds before and after the accident in a write-protected storage system.Different Types of Dash Cams
iSome video recorders have SD cards included. They allow to transmit a part of the video to them.
iSome dash cams are equipped with screens. So you can view the videos you have recorded.
