Sighthound is extremely basic actually. It doesn't support PTZ, it only supports AAC for audio on Mac (it supports some others on Windows), it doesn't support mechanical zoom.... basically, anything your camera does other than video recording, Sighthound is not supported I think it's pretty good software and one day it may be amazing, but currently it's nothing better than an alpha product that still develops many features that most other NVR software packages already support.
Discontinued The program seems to be no longer updated. The latest version, 9.22, released in December 2014, is still available for purchase on the official website.
Great free alternative to BlueIris. Lacks rtps support, but works great with jpegs. Best alternative I have found so far.
