I have blogged several times about how nice the Ubiquiti airVision NVR and the airVision cams are for ease of setup and great value but the UniFi Video cameras take it one step farther.  Not only do they have night vision, but the sound is really cool.  This week I was luck enough to capture a video of a bull elk bugling at his harem in Estes Park, Colorado, the home of the Elk rut.  This one needs no more explanation so turn up the speakers and enjoy!
