Ask HN: Monitor a Tennis Court from a Webpage

2 点作者 smortaz超过 3 年前
Hello HN.<p>I’d like to set up a webcam on a public tennis court so people can visit a URL and see if the court is occupied before heading there.<p>If you have ideas how this can be done relatively cheaply please lmk!<p>Some background info:<p>There is no power, so it has to be solar.<p>It’s outdoors, so weather resistant.<p>There js no wifi, so cell network.<p>Only needs to work 6am to 11pm.<p>Video feed is not needed, a snapshot every 5 minutes or so is sufficient.<p>Will be placed on top of a fence overlooking two courts.<p>Thanks in advance!

LoRa fits the low power and its also long range. I have never sent images over it but for sure its possible but unreliable, as its very low bandwith.<p>I would do some kind of computer vision to identify people, or count them and send that data instead, those operations should be easy on a microcontroller.
