Reads the satellite signal from TV using a webcam and sends it as text to a client running an HTML page for Satellite dish positioning. Useful when monitoring satellite signal strength when positioning a satellite dish. Signal is captured using webcam and sent over network as text to decrease bandwidth usage.
camera-client.py runs on the sender. It extracts the text using pytesseract and sends it to the receiver using SocketIO.
server.js contains a SocketIO NodeJS server to send the extracted text to the receiver.
receiver.html accessed by the receiver using any browser. It receives the text and is used to set the region in which the signal is located in the image.
