If you don't want option 1. You can choose option 2 but note that depending on the location and distance between camera and atem, there could be interference from other wireless devices or walls. If you can have a clear line of sight, wireless HDMI can work well, otherwise it's very unpredictable.
Option 3 is is to live stream the video signal to CDN and have a laptop next to ATEM to download the stream and input to ATEM thru HDMI cable. This method will introduce delay in your broadcast and you need reliable internet connection for both. You also need an encoder at your camera such as Teradek Vidiu.
The cheapest option will always be cable if you are doing this regularly. Just setup the cable once and you can use it for every broadcast. Professional wireless HDMI set is very expensive too.
I was actually informed about the Vidiu through my school's IT professional but presented using a mobile app for the iPad Pro. What's CDN, and how would I use the encoders to send video to the ATEM? Also, cable might not work because we are intending on going far distances and possibly many different rooms in the school. Wireless cables might not be very reliable because of me needing to go far distances.
A CDN is a Content Delivery Network. That's a third party service you push your stream out to; the CDN takes that stream and serves it up to Internet users. You don't need one for cam-to-switcher streaming. Instead, you just need an encoder (which can be a computer or a dedicated box) and something in your studio that can receive video from the encoder and display it (this would usually be a computer.)
PC to PC streaming is very easy to do; you just need a webcam server of some sort, a webcam interface (like the BlackMagic Web Presenter), and software on the client PC to play the stream. (A web browser, Media Player, VLC, etc.)
