I'm in Halifax so I'm quite a ways away from the border sadly.

I'd love to order this 3.6mm lense http://www.m12lenses.com/3-6mm-F1-8-Mega-Pixel-CCTV-Board-Lens-p/pt-03618mp.htm but it would cost $36 to ship to Canada I wonder if I email them if they'll throw it in an envelope with a stamp.

For anyone that cares, these cameras are rated to -10C. Last night the temperature here dipped to -21C and my seven cameras operated fine.

Sorry, I should clarify. I'm replacing the whole camera with a 3.6mm model.

Hey Brutus, Was that the 3.6mm lens you swapped out and is that the "port-holing" you mentioned? Still a pretty good image though. The 6mm can be a bit tight for a lot of situations would be nice to find one as good or better than the OEM lens. That is the lens yep. I am going to replace it with a stock 3.6mm here soon.

That would be VERY irritating if your cameras were outside. Way too many false positives.

I just provided the video to the police

Caught someone trying to get into our locked vehicles last night using my system http://www.reality-check.ca/threads/322013-My-home-surveillance-system-paid-off-got-video-of-a-thief-last-night

The black corners are because the lens isn't as tall as the stock lens so it sits back a little bit in the housing. The black corners are the housing blocking the corners.

Do you recall which 3.6? I believe there are two on the site. One was $2.10 and the other $2.70. $2.10 I may order the $2.70 one and see if it's better. I find this one is pretty blurry around the outer perimeter compared to the stock 3.6mm lens and the lens sits back further in the camera housing so you can see a slight black edge in the four corners where the lens is seeing the camera housing.

Tried some lenses from DX today. The 2.8mm wouldn't fit. I couldn't screw it down far enough to focus it. I replaced a 6mm with a 3.6mm and it's ok but not as nice as the stock 3.6mm lens.

You guys should takes your gripes about return policies to another thread and leave this to discuss the cameras.

I find the IR halo to be pretty common on these cameras.

Anyone know where you can order stock Dahua replacement parts online?

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. I'm in Nova Scotia so I'll let you know how the cameras perform. It doesn't get Alberta cold here but we'll see -25C. My plan if they fail at low temps is to add a heat source if need be. I have access to a top notch Electrical Engineer and he said he can fix me up if it's an issue.
