Enjoy the benefits of having a cellular trail camera sending pictures in real time, while having a sustainable source of energy. Solar-powered trail cameras have more advantages since they work through a combination of solar power technology and Lithium batteries. Before putting the Solar Panel in use, charge it at least 8 hours with the included AC Power adapter. After the initial charge, sunlight will assist the batteries in powering the camera. The Solar Kit is Compatible with all BigFoot Cameras. Once installed the camera batteries may only need to be replaced once per year – saving you a lot of money which will quickly pay for your Solar Charger investment. Output of this charger is 12 volts (2 watts). Note: The sun charges the internal 1500mAH Li-ion batteries inside the Solar Charger. he Solar Charger does not charge the batteries inside the camera. Therefore, you do not need to use expensive rechargeable batteries inside the camera.
