Loop Recording

To keep you from having to manually erase hours of non‐collision footage, dash cams are designed to record over existing footage (starting with the oldest) when the memory is full.

Lockdown Recording

In the even of a crash, many dash cams will lock down the automatic recording. This means it will catch the entire event and save it. A lockdown recording won’t be looped over, so you don’t have to worry about downloading it in the aftermath of a scary situation.

32GB Storage Capacity

Most dash cams take micro SD cards with up to 32GB capacity (about five hours of HD footage). And pay attention to the details—some dash cams come with SD cards included, but others require you to buy one separately. Some dash cams are fussy about the class of the card, so read the reviews to see which SD cards worked for other customers.

G-Sensor

Most dash cams have a sensor that detects sharp turns, rapid braking, and other signs of collision. When you trigger the sensor, the camera saves that footage automatically or with the touch of a button. This type of footage is typically protected from automatic looping, so you won’t accidentally lose crucial video footage.

Transferrable Files

Download high-definition video footage anytime using an SD adapter or USB cable. Some dash cams come with companion software, but not many‐it’s usually your job to find a compatible media player for your camera’s file type.

HD Resolution

Almost all dash cams record in HD (1080 x 720 pixels or more) to help you see license plates and other details clearly.
