First of all, sorry for the long delay. I needed time to digest all the new information . Hey Alpine, thanks very much for all the sound and practical advices. Also, the cameras you proposed are really good examples of what to look for in a good quality camera. The second one would be more in my budget and it looks like it has a lot of features for the price. I didn't know about Wide Dynamic Range (WDR) and IR cut filter before, and now I think I know that those camera are more expensive for a good reason. Hi 3RDIGLBL, I really appreciate the input of a guy actually living in the sub -40s. Here (in the Maritimes (East coast of Canada)) we sometimes get -25C (-13F) three days in a row. A few days during the winter we get -35C (-31F). It could probably go down to -40C also. If the electricity goes off for 4 hours during this time, the camera and heater will stop : -Will the camera turn back on after the electricity comes back? -Will it harm the camera in any ways? -Will it shorten the life of the camera significantly? I mean, everywhere I go, I observe the jobs that others did in the area. Everywhere I see a camera outside, it's in an enclosure. Do they have to replace their camera every five years? Or is it really working? I've found a model that can withstand -60C to +60C (-76F to +140F) : X14N Series Extreme Environment Integrated Day/Night Camera. It's insulated : No heater or blower needed. It has IR illumination. Originally the brand was "Extreme CCTV". Bosh acquired them. Look : alturl dot com/d5zp I like everything about this camera except the price. But if my client doesn't have to replace the camera every two years, it's a cheap camera in my book.

Thanks for the clarifications and the good advices Alpine . I have some other questions that, I guess, are pretty much basic knowledge in the CCTV field (Me: Newbie) : -Can a Higher resolution camera work on a DVR that records at a lower resolution? -If the enclosure specifies it's good down to -25 should I use it for -33 application? -Is a focal length of 4 to 9 mm good to watch a small parking lot (5 cars) and the entrance of a small convenience store? -Please, would it be possible to give one or two examples of a camera with a good quality/price for a minus 35C winter application : Good day/night images; Durability; Good price.
