After the screen is projected on the TV, can the other party see that I am driving the camera?

The camera is on, so you can be seen from the opposite side. If you turn off the camera, you won't be visible across the street.

The camera can't directly project the screen onto the TV because the signal formats of the two are incorrect. If you want to project a screen, you must have a mobile phone, a monitoring hard disk, a video capture card and so on. Specifically, it is to convert the video signal of the camera into a video digital signal and play it through the corresponding software. At present, you can use the digital probe (camera) on the internet to transmit the signal to the mobile phone, and then project the mobile phone to the screen, which is more economical and convenient.
