dash cam just paid for itself during the first week. Dash cam sales have grown 10-20% in the US over the past few years. Here are a few of the "must have" options to look for if you're in the market for HD car cams:
- High Definition Video - The higher the image quality, the easier it will be to see important details, such as license plate numbers, facial features, car colors.. 1080p and higher.
- Low-Light Capability - Many accidents / incidents happen at night. You don't want to lose important details due to dark videos, many models have low-light / night vision modes.
- Ample Storage - Having a large storage card will increase chances that your HD car cam will preserve the footage you need, even if you didn't think to save until hours after the incident. Look for a 32GB card or larger.
- Longer Loop Time - Memory cards don't have infinite space, it records in sections called loops, which are small video clips. Look for a 3 to 5 minute long loop file.
- Motion Detector - This turns the unit on automatically when there is movement or the car is impacted while parked. This is a great feature if you do a lot of street parking.
