How does dash cam work

　　In order to actually see what sets purposeful dashboard cameras except for general purpose devices, it’s necessary to know how dash cams really operate. Unlike general purpose recording cameras, dash cameras tend to be essential affairs that usually lack fancy bells and whistles like power switches and recording controls in favor of rock-solid performance day after day.

　　In fact, a prototypal dashboard camera consists of only a few of basic components:

　　• A video camera: This is the one thing every single dash cam needs. The camera is how it can capture the movement.

　　• Hard-wired power inputs: You can run a battery-powered dash cam in your car when you really want to, but then you have to worry about taking it out to charge it. Wire it directly into your vehicle’s electrical system, or plug it into the ignitor, and no worries about the power.

　　• Built-in or removable solid-state storage media: It’s fine to use a dashboard camera that has built in memory, but it’s better if its memory is removable. Choose a dash cam that accepts micro SD cards and avoid yourself some troubles.

　　Function follows kind in the case of dashboard cameras, thus you’ll be able to most likely get a reasonably good idea of how they work by staring at that distributed list of elements.

　　Without an on/off switch, a dashboard camera is usually wired into a circuit that’s only hot once the ignition key is in the begin or run position. For additional security, and a little risk of your battery going dead, you can also wire the camera into a circuit that’s hot at all times.

　　Without any form of recording controls, dashboard cameras are generally designed to record continuously whenever they’re powered up. Others have a security choice to record only they sense motion. With that in mind, you’ll be able to see how these simplistic devices are designed to automatically turn on and begin recording when a car is driven without the requirement for any input or interaction from the driving force in the least.

　　This can be contrasted with general purpose moveable recording devices. Although you’ll be able to use nearly any recording device as a dash cam, you will have to turn it on and set it to record every time you get in your car. If you imagine a situation where it slips your mind someday, and you simply happen to get into an accident, then it ought to be easy to see the draw of a purpose-built device.

　　How does dash cam work at night? All dash cams can record at night, but as light levels get low, certain technologies like WDR and HDR really help to create a significantly improved clarity in night vision.

　　If you do a lot of driving at night, then we recommend looking at dash cams that have the latest Sony EXMOR sensors for ultimate night vision and enhanced picture quality.
