I run my entire camera solution this way; Axis cameras (all M10 series pointing outside) - and using Blue Iris. I've been running like this for close to 2 years and have not burnt any image sensor yet. I picked up a new M1014 last month (1MP/720 with 2.8mm which covers ~ 80 degrees), and it's great! The entire solution though falls short at night. I do my best to compensate all the cameras imaging for low light (setting up events with schedules on the cams themselves for white balance, etc). My property is well light on the exterior, so that helps. The entire solution works pretty good, but a far cry from having a true outdoor IR cam. You do also get window reflection glare from interior lights (at night), so keep your blinds closed! I've been closely watching the Dahua bullet cams too; Great picture, awesome price. But I fear that they'll stop functioning in a Canadian winter, hence the reason I haven't purchased any yet.

I run Blue Iris too, and as much as I want to buy these Dahua camera's, my fear is that they will stop working when temps in a Canadian winter hit -30 Celsius. So airing on the side of caution as I cannot have my system stop working due to cold temps.
