Need your advice

Hey everyone! I'm trying to find my way through building my own custom sewer camera for inspection of 3 inch pipes and above. I've got some basics somewhat figured out, but I'm looking for help in regards to a built in 512hz "sonde" transmitter that i would like to know if I'm able to build myself. Most sewer cameras have these installed on board. I have lots of other questions but this is my first post, so I'll keep it to the point. Grateful for any advice!
 
What kind of data is your Sonde transmitting? It is just a simple sine wave, a square wave signal or is the signal encoded with location, distance or depth data? What kind of encoding or modulation is used (AM/FM/PSK/PWM...). What signal strength is needed? What material are you using for the enclosure? What power source? How sensitive is your receiver?
