The Petzi Treat Cam is designed for home use. Hotel WiFi often has extra security (firewalls, content filters, proxy servers, MAC Address blocking, pay walls) that prevents adding the Treat Cam (or any other device not designed for Web browsing) to their network.
For those who travel with their Petzi, we recommend getting a WiFi hotspot from their cellphone provider.
Having said that, some customers are able to get connected if they worked with the hotel's Internet support. You may need the MAC Address of your Petzi. We can provide that for you, just let us know Petzi's serial number.
Of course, you must reset the Petzi and add it back to your phone as you would anytime you move the Petzi Treat Cam to a new network.
