No, the update only overwrites system files. However, it is highly recommended to back up important footage because the update process may require formatting the SD card for best results.
Firmware is the low-level software embedded in hardware that controls how the device operates. The LDW931, like any sophisticated piece of technology, requires periodic updates to address three core areas: security vulnerabilities, operational bugs, and performance bottlenecks. The new update likely responds to discovered weaknesses in previous versions, such as potential data interception points or stability issues under heavy load. Furthermore, as external systems (e.g., cloud platforms, mobile apps, or network protocols) evolve, the LDW931 must adapt to remain compatible. Thus, this update is a proactive measure to ensure the device does not become obsolete or compromised. ldw931 firmware update new
