I need to build a prototype with Arduino Nano of a multiple video night vision and pir sensors transmitting to a receiver with a High definition small touch screen when the sensor is triggered and I can switch from the receiver the view of the single camera I want. The project should include the code for the transmitter and the one for the receiver and the stl file for the 3D printing of the trasmetter and the receiver containers. The transmitter container should be as small as possible, considering it needs to support a small battery and transmit to long distance with the best quality as possible. Mini usb rechargeable and mini solar panel included to recharge. The receiver should be as thin as possible and it should have a thin battery both transmitter and receiver batteries should be mini usb rechargeable with the indicator of the battery life. The scope of the project is for 4 video pir transmitters and 1 receiver (initial scope)
