In this video I build a fully wireless ESP32 pan/tilt camera system that has basically no noticeable delay. There’s no Wi‑Fi link between the controller and the servos—I'm using ESP‑NOW plus a simple joystick transmitter to drive two servos in real time. On the camera side, I’m using the ESP32 camera web server example (from the Frenov tutorial), so I can hit “start stream” in the browser and then use the joystick to look around the room like a DIY FPV/POV rig. I walk through the transmitter wiring (X, Y, and SW) and explain an important gotcha: I power the joystick from the ESP32’s 3.3V pin even though the joystick module has a 5V pin, because the ESP32 ADC reference maxes at 3.3V. Feeding it 5V can clip your readings and you can risk frying a pin. On the receiver side, I show my pan/tilt servo setup and the power rules—don’t power servos from the ESP32. I use an external 5V 4A supply, and I recommend adding a big capacitor (around 1000µF) on the servo rail to help with voltage dips that cause jitter. I also show what to grab from Serial (Wi‑Fi channel, MAC address, local IP) and where those values go in the transmitter and receiver code.
