Compare the 70mai RC11 and RC14 rear cameras. See which add-on is compatible with your dash cam and which features matter most for your recording needs.
Quick answer
Choose the RC11 for most 70mai dash cams (A510, A810, A800S, A500S, A400, A200, S500) and the RC14 exclusively for the 4K Omni or M800. The RC14 offers a slightly wider 134° view versus 130° on the RC11.
Compatibility is the deciding factor
The RC11 and RC14 are not interchangeable across all 70mai dash cams. The RC11 works with a wide range of models including the A510, A810, A800S, A500S, A400, A200, and S500. The RC14 is specifically designed for the 4K Omni and M800.
Both cameras serve as a rear or interior view add-on, but your dash cam only supports two channels. If you connect a rear camera, you cannot also use an interior camera, and vice versa. Plan your setup accordingly.
Field of view difference
The RC14 provides a 134° viewing angle, while the RC11 offers 130°. This 4° difference is modest but can capture slightly more detail at the edges of your rear view. For most drivers, the RC11's 130° angle is already sufficient for monitoring traffic behind you.
If you frequently drive in tight parking spaces or need to see more of the rear quarters, the extra width on the RC14 may be beneficial. Otherwise, the RC11's field of view is adequate.
How to choose between RC11 and RC14
- Check your dash cam model: Look at the model number on your dash cam. If it's A510, A810, A800S, A500S, A400, A200, or S500, the RC11 is your compatible option. If you have a 4K Omni or M800, the RC14 is required.
- Consider the viewing angle: The RC14 offers a slightly wider 134° view compared to the RC11's 130°. While the difference is small, the RC14 captures a bit more peripheral detail. If you need the widest possible rear view, the RC14 is the better choice, but only if your dash cam supports it.
- Factor in the price difference: The RC11 is priced at USD 11.99 (catalog comparison USD 19.99), while the RC14 is USD 18.29 (catalog comparison USD 29.99). The RC14 costs about USD 6 more, reflecting its compatibility with higher-end dash cams. If budget is a concern and your dash cam is compatible, the RC11 offers a lower upfront cost.
