B.Battery life
If the device does not detect a moving object, the device will go into
sleep mode to reduce the power consumption of the device.If the device
detects a moving object, it quickly wakes up and starts within 1
seconand takes a screen-shot and records a video.
WARM TIP:
The device uses a ternary lithium battery, when the battery is in a
low-temperature environment, the internal chemicals of the battery will
slowly solidify,the battery charging and discharging performance slows
down, resulting in a decrease in the capacity of the battery, the life of
the device will be seriously reduced.And the lower the temperature, the
lower the battery capacity will be,when the temperature is below -20
degrees, the battery has the probability to enter the self-protection
mode and shut down.But if the temperature rises,the battery will
automatically return to its normal state.In cold winter, if the device
needs to be charged, it is recommended to take the device back inside
the house and set it aside for an hour, the warm air in the house will pull
up the temperature of the battery before the charging action.Then
recharge it.
Why does the device have a poor battery life?
• The working time of the device determines the battery life.The more
frequently the PlR wakes up and the number of alarms, the longer the
working time of the device.Please check whether the number of alarms is
too frequent. It is recommended to adjust the motion detection sensitivity of
the device appropriately and set the alarm interval and alarm time plan.
• Check whether there are objects within the field of view of the device that
interfere with and trigger the PlR sensor, such as outdoor units of air
conditioners, moving cars,passing pedestrians, etc. The angle of the device
can be adjusted appropriately to avoid these objects prone to cause
interference
• The battery capacity will be reduced in cold weather, which will affect the
range of the device.
