After some quick research, I found out:
1. The battery is made by OceanSun. Although I could not find the exact model# from their website. I found out all of their Li-Po batteries have a max operation temperature at 60C.

2. The battery has three wires. The white wire should be the thermistor.
3. The system power management/battery charger (ACT3780) has a thermal protection (thermistor pin).

4. The DC-DC step down converter (ACT4070) has a shut down temperature of 150C.

So, it seems like Winycam set up the cam so that it cuts off the battery when the battery temperature is at 60C, and the cam will shut down all together at 150C (very unlikely).
Now, I’m going to keep my IR thermometer in my car to verify my theory.
