...it voltage of solar panel: 5.8V, working current of solar panel: 20-200ma) or external 5V 500mA adapter can be used for charging. If it rains for a long time, the adapter can be used for charging. When charging, the red indicator light is on.
When fully charged, the green indicator light is on..
Easy to Operate: The sensing distance can be up to 10 meters, depending on the size and temperature of the animal. (the larger the animal, the farther the distance, the higher the temperature, and the closer the distance.) Infrared sensing angle: 110 degrees. Sensitivity and sensing distance are adjustable..

The Controller is specially designed for PStation 4 console, adapting Dual Shock 4 wired controller program, it's a perfect replacement for Original PS-4 gampad with much less cost..
In addition to induce tilt angle of the controller, it can also capture the 3 axis acceleration information of three-dimensional space X、Y、Z, and transmit all information captured to the game system quickly. With this function,players can use this PS-4 controller to operate special games..
It’s equipped with latest motion sensing technology, built-in three-axis gyroscope and three-axis accelerator. With the three features, it can detect omnidirectional dynamic information including Roll, Pitch and Yaw..
It’s also featured with a new function: dual-point capacitive sensing touch pad on the front of the controller. The share button makes social interactions easy with instant gameplay video and screen uploads..
Note: The central button is a tactical button and not a touch sensitive pad. The controller does not have MIC and Audio Jack function, headsets are not supported. The controller is dedicated to PS-4 and PC(Windows 7/8/XP,Windows 10 system may be incompatible)..
