Are heaters and blowers for outdoor cameras REALLY needed? That is the question.....

I got a bunch of Axis cameras in unheated outdoor enclosures w/o blowers mounted outdoors. They have been outside during many days of +90F temps and single digit F days without any problems! So, is money wasted by ordering outdoor enclosures with heaters and blowers??

Can't say for sure, but the cameras do create some heat by themselves. I would think the issue is probably more condensation in cold temps, for example, the camera gives off a little heat, the lens is warmer than the outside temp, it could possibly get condensation on the lens.

For the summer, heat is just the enemy of electronics, so the issue is longevity rather than if you'll have immediate problems.

You are 100% correct. Some of my cameras give off good heat, but NEVER noticed any fogging due to condensation. Actually, I was more concerned about too much heat during the hot summer months than the cold as some of my cameras throw off a lot of heat (hahaha - a built in heater!). All of my M1114's are mounted in el cheepo chinese made $15.00 outdoor enclosures with slight modifications....

As long at the 90 degree weather is for months on end, you shouldn't have much of a problem Its when you get 90+ degree weather for days on end that your going to potentially damage your cameras.

As for the cold, condesation is one worry, but I have seen a few cameras that litteraly "freeze" when it gets below 28-25 degrees farenheit. They litteraly wont cut back on unless the temperature outside warms up or you bring them inside to thaw.

This winter we had plenty of days/nights that were in the single digits and during the summer we has several days where temps go over 100. In all cases the cameras works flawlessly.

Maybe I shouls run a test and "cook" a camera in my oven while streaming live until it dies.

The M1114 doesn't have a cut back filter, so not an issue with that freezing, but it does have an auto iris, so that may freeze in place. It may just pay to move to So Cal, live by the beach, 75F max in summer, 50F lowest in winter. Works for me, haha.

I may take your advice. Cost of living So Cal is most likely cheaper than the New York City metro area. Sh!t, I pay almost $12,000 in property taxes a year for my .33 acre dump over here........

Certainly lower in property taxes and you don't need winter clothes, winter tires unless you go to our moutains during the winter.

I learned allot by this thread. Wasn't even aware of such features with outdoor enclosures (which I'm actually researching/shopping for right now!)

Sometimes condensation can really build up on the electronics in these outdoor type of enclosures. You really need something to protect it from weather extremes. It can take time but it will eventually damage your electronics. Check out www.ddbunlimited.com they have cooling and heating along with other accessories that can help prevent damage to your electronics!! Very Happy

Since the time I originally posted this question to the forum, I purchased an Axis M1114-E. it is the regular M1114 in an outdoor enclosure. The enclosure has no heater or blower, but appears to be 100% sealed. There is what appears to be a black rubber o-ring (for lack of better descriptive words) that provides a air tight seal between the two halfs of the enclosure. there are no air vents. Included with the enclosure is one of those bags that has metrial to absorb moisture. Since the M1114 has no moving parts such as a mechanical IR cut filter, it should be OK in most outdoor climates w/o a heater or blower.

I have 4 more M1114's outdoors in cheap Chinese made outdoor enclosures for the past year or two. In New Jersey we get temps above 100 degrees in the summer and single digits in the winter. I never had any problems.

Many moons ago, I had lower end Panasonics (BL-30A and many others like it) outdoors in cheap unheated or cooled enclosures. One camera was hung just below the soffit fully exposed w/o an enclosure, but out of rain's reach. I never had a single problem and those cameras still work well today at a friend's house running 24x7 outdoors in non-heated or cooled enclosures.
