Replacing existing camera

I just received a warranty replacement pan cam.
Can I just swap out the cameras? ie, ‘living room’ old camera is replaced by the warranty unit?
Or do I have to ‘add a product?’
I had an SD card in the old one and don’t want to have to reset the SD card.

You have to add it as new, the new one will have it different Mac ID But it will not Reset the SD card , if you are really worried about that leave the card out till the camera is set up
