LOL they’re using the DJI Video system on those drones. The antennas are DJI.

And that is the absolute worst thing they could have used. DJIs wall penetration sucks ass and since schools are typically built sturdier than regular houses, they’ll have 2 rooms of nice image that turn into a blocky Minecraft mess right after. They should have gone with a high power analog system since that would give the best wall penetration.

Also, they only recently allowed BVLOS flights in the USA - might be for these things only.

To add to that: those drones can be hacked, but only if you press the WiFi button on the drone itself, since it deactivates that when powered on normally; or if you connect it via USB. Also, if they control it via remote - the DJI remote is worse than ELRS. A 868 ELRS module would be better penetration wise but worse for latency. You can’t hack ELRS remotely, since they are secured via passphrase. If your passphrase is "I don’t like where this is going", you need to install that on the drone and the controller. Any drone with that phrase can be controlled with any controller using that phrase.

Also, the drone in the picture is likely a 3“ cinewhoop. Those are made for lift, not for speed. But even then, the maximum weight of one of those would be 1200 grams. Looking at the pictures, 600 grams could be the battery and about 200 the drone, that leaves 400 grams for deadly things.
