Dash cams are a useful car accessory. They work like the second pair of eyes on the road. This is important because even if one drives carefully, there is no assurance that others drive responsibly as well. Besides, they can work as a safety and precaution measure to protect against unnecessary traffic stops and insurance fraud attempts. For those looking to purchase a dash cam, here are a few things to know before buying one. Cost of the dash cam This is one of the first things to consider before buying a dash cam. Top dash cams are usually priced between $30 and about $500; however, the price generally depends on the model and the features offered.

Besides, it will support larger SD card storage sizes with automatic Wi-Fi video uploads. The higher-priced models will have multiple-angle viewing capabilities.
