Dashcams are now commonly used in personal and business vehicles. These devices have many benefits, including catching criminals and providing evidence in car accidents. They are also useful in clearing up insurance issues and fighting traffic tickets. Many US states now have special programs for reporting bad drivers.

The technology behind dashcams has improved since the 1980s. Some models offer features such as GPS tracking, night vision, and high-resolution video. Others offer automatic uploads to the cloud. A few models even include voice control.

A dashcam is a device that you can strap to your car’s windshield or dashboard. It records events, and then stores the footage on a memory card. Some models come with a removable SD card for easier storage.

Some models have a touch screen, and others have a rearview mirror. Most dashcams work on 12V power, and turn on automatically. If you plan to record during a road trip, you may want to get a dashcam with a larger SD card. This way, you won’t have to worry about deleting the oldest footage.

The video files are usually segmented into one-, three-, or five-minute segments. This is known as “loop recording” because it records over the oldest footage. Some higher-end models allow buffered recording, which means they record for a few seconds before impact.

Higher-end dashcams also have motion sensors that capture footage when your vehicle is parked. Other features may include parking mode and a GPS location save. Besides providing evidence in car accidents, dash cams can help you clear up insurance issues. In fact, some models come with an emergency calling feature. You can set alerts for lane departure, distracted driving, and other incidents.

The best dashcams will have a low initial cost and a variety of features. For instance, the Dash Cam Plus has an Alexa-enabled voice control feature, which allows you to operate it by talking to your mobile device. At the same time, it offers a 24-hour parked-car monitoring system, Bluetooth connectivity, and night vision.

You can even get a dashcam that’s designed to fight traffic tickets. If a driver is caught driving under the influence, this device can provide a clearer picture of what happened. Moreover, it can help you prove your innocence in a car accident lawsuit.

Dashcams have many other uses, including recording animal encounters, paranormal activity, and capturing a memorable moment. They can help you catch vandals, deter theft, and more. But most importantly, they can serve as a reliable witness in the event of a car accident.

If you are looking for an affordable dashcam, you can look into models that have a price tag of less than Rs 3,000. Unlike many devices, these models have basic features, and they can be installed and used within a few minutes. However, if you’re looking for a dashcam with more features, you may find that they cost more.

Some more expensive cameras may require additional hardware, such as capacitors. Capacitors allow the device to be more resistant to operating temperatures. Additionally, they can store a temporary charge for the device.
