Is 16GB Enough for a Dash Cam?
1 Answers
It depends on the video resolution setting. The higher the resolution, the more storage space it consumes. A 16GB memory card can record for approximately 4 hours at maximum. A dash cam is a device that records images, sounds, and related information while the vehicle is in motion. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also be used to document the journey through challenging terrains. More details are as follows: 1. Most dash cams do not have built-in memory and rely on memory card expansion or portable digital hard drives. For Micro-SD or SD card expansions, capacities vary from 2GB, 4GB, 8GB, 16GB, to 32GB. For portable digital hard drives, capacities can range from 250GB, 500GB, to 1000GB. 2. To meet larger video storage needs, the configuration depends on personal requirements. Generally, the larger the memory, the higher the price of the dash cam. The appropriate memory size should be determined based on the recording clarity of the dash cam and the storage capacity of the camera. High-definition dash cams offer 720p and 1080p resolutions. A 4GB card can record 720p video for about 1 hour, while 1080p video occupies nearly twice the space of 720p. 3. Generally, a video resolution of 1280*720 is sufficient to clearly capture the license plate of the vehicle in front, while the plates of adjacent lanes may appear relatively blurry. Additionally, the light sensitivity of the dash cam's CMOS chip and the quality of the external lens glass directly affect its nighttime recording performance.
