Disconnect from campus WiFi when possible. When not, stick to the Brown Guest SSID with MAC randomization. Always use a VPN.

For swipe cards, tailgate into buildings. Brown's building access is so restrictive, and the experience of being locked out is so universal, that virtually all Brown students are conditioned to hold doors open for each other.

For cameras, there isn't as much as you can do to protect your privacy. The camera map included in the blog post displays OpenStreetMap data. It's very hard go anywhere near Brown without getting caught up in its camera dragnet. You usually cannot avoid cameras altogether, but you can minimize your exposure! And the one bright side of 2020, in this regard, is that it's normalized wearing a mask!

IP you can use a VPN. Mac you can use the randomization method mentioned in the article. Swipe Card/Cameras there is nothing you can do.
