Some variants include sensors alerting the drivers to sections of the road with surveillance cameras. Should the driver be over accelerating, the recorder will signal that the speed should be dropped. The road conditions could change rapidly and none of the drivers have insurance against mishaps or other unwelcome events. Sometimes cops find it difficult to immediately identify the guilty party. The driver will be helped to win the case by a good dashcam that catches precisely everything that was happening during the trip, which is why it’s important to understand what to look for in a dash cam.
Thanks to it, you will be able to prove your blamelessness to the police and the court, settle a traffic conflict in your favor, and identify whoever damaged your car in the parking lot. Modern dashcams also have greater functionality, which facilitates simpler and more convenient cooperation. There are many companies manufacturing dash cameras. Models abound in the stores and on the Internet, thus choosing only one suitable model can be rather difficult. Which characteristics of these tools would be required to review before buying them?
What to look for when choosing
Create and look at Design. Design and look separate dashcams into regular setup devices, hidden type equipment, and mirrors. Classic systems most usually show themselves as medium-sized rectangular or square boxes positioned on the windshield. These gadgets have a big lens, a screen, and a battery. Smaller size defines miniature dash cams; they do not disturb the view and are difficult to see when looking out the cabin. These devices barely are produced with batteries and are not built with screens.
Mirror dash cameras represent the most modern form factor. Attached to the cabin's rearview mirror, they use its functions in addition to those of a dashcam. The resolution determines the image quality since it is proportional to the sensor attributes. Popular versions might have its size ranging from 1 to 3 MP. In expensive models it can be more valuable. The matrices provide 4K (3840 by 2160) resolution from HD (1280 by 720 pixels). Most typically one meets Full HD (1920 by 1080) and Super HD (2304 by 1296).
Screen resolution
This value expresses the lens's covering of the surrounding area. The highest values fall about 170 o. Still, distortions can arise at the margins with such settings. Users that practice recommend using tools with a coverage ranging from 120 to 140 degrees. With such a design, the viewing angle is also rather wide; the distortion at the edges is not so significant. The speed of the dash cam, image quality, and compatibility with additional features are decided upon by the electronic components. These days, chips in about 500–700 MHz range.
Among leading producers: Ambarella, Novatek, MediaTek, etc. Before purchasing a dashcam, it is recommended to check the specifics on the processor and go over several reviews about the same. A car dash cam can show the mode the gadget is running in on a medium-sized or small screen. Additionally exist models without displays at all. To see the kept videos, one can connect them to a smartphone or a tab. Although they are simpler to operate, screen-based devices cause the device's total size to be bigger, therefore these dash cameras could obscure the driver's view.
Viewing angle
Enough space for setup and viewing recorded files would be a little display with a 1.5 to 2.5 inch diagonal. Most of the models have lengthened their diagonals to 4 inches. Regarding video recorders connected to mirrors, their dimensions may reach up to 12 inches. The gadget is set on the dashboard, mirror, or front windshield. Using a suction cup or double-sided tape, they fix themselves on the glass and panel. Rigid or flexible fasteners bind them to the mirror; the connection becomes detachable, so the item can be taken off with ease.
While removing the suction cup is simple, it also securely retains the gadget in place on the glass. One of its shortcomings is that the material stiffens and the suction cup could come free in cold. The double-sided tape is the more dependable choice, but applying it leaves marks on the glass long after it is removed and is not reusable. Alternatively the dash cam might be mounted on another bracket. Dash cameras might have built-in rechargeable batteries or run on the automobile onboard network.
Conclusion
Should the model run on the car's energy, the recording device also shuts off immediately upon loss of this energy source. In this case, the last video recording may disappear. Both during the voyage and when the car is parked, batteries let the dashcam record independent of their connection to an external power outlet. There are other gadgets that only engage when the G-sensor is turned on and can remain in the standby state over an extended period. Most of the devices have one camera, which just records events straight in front of the car. We call these video recorders single-channel.
There are certain equipments with dual channel video transmission. The camera in them could be built-in and pointed at the cabin. These devices record every incident in the vehicle. Additionally available in case of an external camera or a rearview camera is the opportunity to connect a wire. Either a suction cup fixed on the body near the license plate or put on the rear window makes this kind of dashcam. Later in the examination of traffic accidents, the camera shows a scenario behind the car. Convenience drives most people to use rear cameras for parking.
