6. Battery Protection Mechanisms:
   • The device may shut down prematurely to protect the internal components if the battery power is insufficient to operate effectively.

Solutions:

1. Optimize IR Flashlight Usage:
   • Reduce the IR Level by adjusting it from IR3 (highest power setting) to IR2 or IR1 through the menu to conserve power.
   • For longer durations, consider using an external IR flashlight to supplement or replace the built-in IR flashlight.
2. Limit Video Recording:
   • Record videos only when necessary and avoid prolonged recording sessions to save battery power.
3. Use a High-Quality Battery:
   • Replace older or low-quality batteries with a high-capacity 18650 lithium battery from a reliable manufacturer.
4. Ensure a Full Charge:
   • Always fully charge the battery before use, and ensure the charger is functioning correctly.
5. Adjust Screen Settings:
   • Reduce the screen brightness in the menu settings and activate the screen saver feature to minimize power usage during idle times.
6. Carry Spare Batteries:
   • Keep fully charged spare 18650 batteries on hand for extended usage.
7. Inspect Battery Contacts:
