A retired thin client is not e-waste. With a light Linux it becomes the enquiry-desk kiosk, the attendance screen or the office notice board - jobs that need reliability, not power, and that a fanless silent box does beautifully.
Offices retire thin clients in working order whenever a server project changes. The boxes are slow by desktop standards - and perfectly fast for the jobs that only need a browser, one page and total reliability. The best second life is a boring one: one job, auto-start, no user data.
👆 One job per box. The moment a repurposed box needs three jobs, it starts failing at all of them.
A lightweight Linux desktop - Debian with Xfce, or a lite edition built for old machines - runs comfortably in the 2 GB class where a modern Windows cannot. The box stays fanless and silent on a wall or a counter, draws a few watts around the clock, and a locked kiosk configuration gives the public nothing to break. It is the same appliance logic that made the box good at its first job.

Each is one job, started automatically, touched by nobody.
Storage is small - the OS plus a browser is the budget, not a file archive. Old Wi-Fi chips can be stubborn under Linux; prefer the LAN cable the box was born for. High-resolution video will strain old graphics, so kiosk pages should be light and camera views should use the low-bandwidth sub-stream. Set these expectations at installation and the box will quietly outlive the project that retired it.
Wipe the previous configuration and passwords completely - a retired office box can carry a stranger's server addresses and settings. Set fresh credentials, keep the Linux updated like any other machine, and if the kiosk only displays public information, place it on a separate network segment away from office data. An updated, single-purpose Linux kiosk is one of the lowest-risk devices on a network.
The video's comparison doubles as a used-market guide - the models it ranks tell you which retired units are worth picking up for kiosk duty.

One or a few camera streams at modest resolution, usually yes over wired LAN. Many high-resolution streams will exceed its decode power - test with your recorder's sub-stream, which exists exactly for light viewers like this.
Yes, with basic hygiene: wipe the old configuration, set fresh passwords, keep the system updated, and if the box only displays public information, keep it on a separate network segment from office data.
