How do I retrieve a CCTV camera stuck in a wastewater network, DN 200 mm, at a depth of 4 lm without digging it out?

How far down is the camera?
17 lm from the manhole cover
Hello, you could try to place an inflatable plug/pneumatic balloon counter-clockwise (to protect the camera) and push the whole lot with high-powered nozzle. Good luck.
Alas, already done, without success.
You might try to figure out why it’s stuck (collapse, shift of pipe or other) and try to move if possible using a cleaning auger or rod. Good luck
Using a cleaning auger/rod seems to me to be a good idea. If it can fit under the camera body, then you have a chance of pulling it back up.
