Hi, I would go for AXIS P3215-V (no audio) or P3365-V (internal microphone or external audio input). Both fullHD, varifocal lenses with max about 90° horizontal FoV, vandal resistant dome cover. Put CamStreamer application (http://camstreamer.com) on board of camera and you have a nice solution...
Hi guys, we can not do it on Hikvision (yet), but we have a nice solution for AXIS. http://camstreamer.com ... small application sits right on the camera and streams directly to YouTube Live. Check CamStreamer channel on YouTube for many live cameras powered by CamStreamer.
