I bought an outdoor security camera, with a PIR sensor, which records when motion is detected.

 

I've only had it a couple of weeks but often at night the picture goes all blurry but it comes right after sunrise.

 

Consequently I'm not getting many recordings through the night.

 

It doesn't happen every night though, and on the nights it stays clear we get good night vision recordings. 

 

Is this condensation? And how can I stop it from happening.

"heater kits", these are commonly used in outdoor cameras. Maybey see if you can google up somthing that might fit inside the housing? It will need to tap off the power you are running to the camera.

could you not just put some silica gel packs inside it? if its sell sealed the gel will absorb the moisture and it shouldn't get any more inside it

@goosey , thanks, but it is battery powered and no other power is available.

 

 

 

@jase2985 , the moisture is on the outside of the lens/sensor area. There is no moisture inside it.

@jase2985, no it is not in direct sunlight, it faces south and has a lot of shrubbery around and behind it.

Try a shroud that just over the top of the camera - should overhang the lens area by a couple of cm





My thoughts are no longer my own and is probably representative of our media-controlled government

It already has a wee hood, maybe its too small.

 

Will try something larger.

 

Thanks.

As long as it's sealed and not in direct sunlight it shouldn't be condensation. 

 

I know a number of my cameras (especially those close to foliage) quite often get covered in tiny cobwebs, these aren't visible during the day, but at night the IR reflects off them and cause blurring.

 

Might not be the problem, but definitely worth a check.

 

 

 

Other option can be if the IR isn't shielded well enough from the lens it can cause blurring

Re-read your original Post,

 

Definitely can rule out IR blur.

 

sounds almost identical to my cobweb issue, this came and went as the culprits made their webs, some nights were much worse than others. A little outdoor bug repellent solved the problem for me.

@mistenfuru , yes, the wee spiders are another issue!

 

It is sealed, and not in direct sunlight.

 

It is condensation that collects on the outside of the camera.

Weird, usually the heat of the cameras IR LEDs will protect against that, any other models usually have their own built-in heater.

 

Do you have the particular brand/model number? if it does have a heater this can most likely be set to turn on/off at specific times. I don't think the larger shield will protect it as it's not Dew, it's more than likely caused by the internal temperature of the camera lowering below outside temp. some way of warming it slightly could resolve the issue.

Its an Arlo Pro outdoor wireless camera.

 

It doesn't happen every night, just sometimes.

Yeah, that's really odd, I see on Netgears site there's a few people with similar sounding issues, most caused by Dew and fixed by larger hoods.

 

Other than that I'm as stumped as you are, I would have thought Arlo's being battery powered would keep themselves warm enough to stave off condensation.

I bought some rain-x product to see if that will help, but now I can't find it!
