Can I have cameras in more than one shed?

Yes, you can have cameras in more than one shed in one of two ways.

1
An additional wireless link. You can connect multiple sheds using additional pairs of wireless transmitters. (See diagram below). This is done with the "Additional Shed Kit".
2
Via a cable. You can run a cable up to 100m. If it is possible you can connect additional sheds by running a cable.
