<!-- BUG REPORTS ABOUT BETA VERSIONS OF UNIFI / UBIQUITI FIRMWARE OR EARLY-ACCESS/BETA HARDWARE WILL BE CLOSED WITHOUT A RESPONSE. ALL BETA RELEASES FROM UBIQUITI ARE UNSUPPORTED -->

**Describe The Problem:**
<!-- A clear and concise description of what the issue is. -->
During discovery of the protect cameras there will be only max. 5 devices found. In fact available are 7 cameras in unifi protect.
I even tried to disable some of the first devices in homebridge-unifi-protect to hopefully see the others, but this reduces the available devices in homekit only to 4.

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
More than 5 unifi cameras needed, then start Homebridge and discovery shows 5 cameras in log.

**Logs:**
<!-- In order to be helpful, include the relevant logs from Homebridge, if applicable. -->
