Can Tesla Dash Cam Save Footage Continuously?
1 Answers
Tesla dash cam can normally save footage on the memory card for one to two years. How long the recordings remain before being overwritten depends on the maximum supported capacity of the dash cam and the size of the memory card. Below is additional information about dash cam memory cards: 1. Common memory card sizes for dash cams: Most dash cams on the market support 32G, while some support 64G. The Mingju M2 panoramic dash cam, an industry-first national patent-subsidized product, features a single unit with 4 lenses, dual 1440P resolution, dual Wi-Fi, and dual memory, supporting up to 256G—currently the largest memory capacity supported by any dash cam. Due to technical and cost limitations, most dash cams have capacity restrictions, typically maxing out at 32G. If a 64G card is used, the dash cam will only recognize the first 32G, rendering the remaining capacity unusable. Therefore, using a 64G memory card in a 32G-limited dash cam is wasteful, as it can only utilize 32G or fail to recognize the excess capacity. 2. How to evaluate dash cam quality: Assess based on memory usage over time. For a 32G memory card at the mainstream 1080p resolution (which offers suboptimal quality), approximately 120MB of capacity is needed per minute of recording, equating to about 7G per hour. For 720P resolution (an outdated standard with poor quality), around 80MB per minute or 4.7G per hour is required. Many 720 or 1080 products are misleadingly marketed as "high-definition," imitating higher-end 1296 or 1440 (currently the highest-definition) products. With a 32G memory card, a 1080P configuration allows continuous recording for about 4.5 hours. For dual-lens setups (sharing one memory card), with the front at 1080P and the rear at 720P (the highest resolution supported by most rear cameras in China), recording time is approximately 3 hours. The Mingju M2 stands out as the first domestic product to support 1080P for both side and rear views in a single dash cam unit.
