Waterproof low latency camera compatible with esp32 or similar low cost boards

I am looking for a waterproof (outdoor) camera that can achieve 30fps (latency less than 30ms) at 640x480 or 320x240 for an agricultural application that is compatible with ESP32 or similar low cost boards. I also want to be able to do really simple image progression on the board.

Do you think is better to use ESP32-CAM board with a waterproof case like this : Waterproof Case Underwater Housing Shell for SJCAM SJ4000 SJ 4000 Sport Cam For SJCAM Action Camera Accessories - AliExpress 44

Or is it better to use an FPV camera with ESP32?

For me the low cost is also important (under 50$ per board and camera together).

Thanks for your time and you can of course suggest me another board or another way to achieve this.
