I've been trying to find an outside security camera for years my only two requirements are 1. resolution greater than 640x480 2. able to be used outside in temperatures lower than 0°C (preferably -20°C).
There's nothing out there and anything close is thousands of dollars and commercial/industrial only.
I don't want to seem like I'm shilling for Geovision in this thread. I have two clients who have Geovision cameras and they have had great luck with them.
That camera is housed in an outdoor enclosure rated at -40°C and has a 1280x1024 resolution (there are higher available in that product line). That's about a $700 camera. I haven't worked with that model, personally.
Thanks but that's what I would class as industrial. I'm looking for something I can set up at my parents, aunts, uncles places connected either wireless (preferred) or cable to a standard PC (Win/Mac).
No offense but that camera shown in that link would make the place look like a crack house or Hells Angels clubhouse.
D-Link makes a nice 360 degree fairly low profile camera the DCS-6010L but it's not very durable it can't operate under OC.
Outdoor cameras traditionally have been housed in a weatherproof, heated enclosure. Not sure if this is still the case. Maybe you need to be looking for camera enclosures and cameras as separate items.
The problem is infrared light doesn't go through plastic so at night when video surveillance is most often needed it's useless.
An IP66 rated (may be overkill) simple camera is tough to find it may be out there somewhere I'll find one! I'll have to pick the brains of the surveillance guys at work they use Pelco but that's industrial.
