+A web app written in Go to monitor IP cameras for motion, storing moments when motion is detected.  
+
+Primarily made to try out Go web development, repo can be found here:
+https://gitea.broodjeaap.net/broodjeaap/StreamWatcher
+
+Should probably not be seriously used, there are better alternatives :)
+
+## App
+
+### Streams
+IP cameras being monitored can be viewed on the main page:  
+![streams](/img/streamwatcher/streams.png)
+
+### Stream page
+The stream view shows the current IP cam view and areas being monitored for motion:  
+![stream](/img/streamwatcher/stream.png)
+
+### Stream add area
+Adding a monitored area is as simple as dragging a square onto the view:  
+![stream_add_area](/img/streamwatcher/stream_add_area.png)
+
+### Stream area view
+A stream areas moment can be viewed with a web 'player':  
+![stream_add_area](/img/streamwatcher/stream_moment_player.png)
+
+## Method
+
+The day of the week can be caculated by:  
+`(day value + month value + year value + century value + leap year value) % 7`
+
+Every one of these value comes from a set of constants or is calculable from the date.  
+This app helps you practice memorizing and calculating these values.
