Seeking Help with CPI System—How to Regain Control of Thermostat and Monitor Cameras Manually?

I recently bought a home that came with a CPI inTouch system, which controls everything from cameras and sensors to the door lock and thermostat. However, I don’t want to renew the contract with CPI, but it seems like I can’t control the thermostat without it, as the control is locked.

I discovered the master code (2001), which gives me access to the advanced security settings on the panel. Does anyone know how I can release control of my thermostat? Also, if anyone has tips on how I can manually monitor the cameras and sensors through the existing system without using CPI, that would be a huge help.

Details: The system is a Qolsys RevG with Linux version 3.4.0 build 20191106. Any advice or tips would be greatly appreciated!
