The Graveyard - Products No Longer Supported => IP Cameras => DCS-2332L => Topic started by: rstark18 on January 17, 2014, 02:43:10 PM

I had my cam pointed down the driveway and the street was in view in the upper part of the frame. I wanted to stop getting notified every time a car drove by so I angled the camera more down. After doing this I started getting a TON (every minute or two) of false positives. I went back to my original position and it's back to normal. Very frustrating.
Does having things closer to the camera affect PIR sensitivity?
We really need better PIR adjustment on this cam!
Here are the two views:

How long is that driveway? 60 ft?
PIR doesn't work that far. 15 to 20 ft.
I think you are picking up heat fluctuations on the driveway.
What happens on cloudy days?

Good guess. It's about 60' to the street.
For the last two weeks since I turned on PIR I ONLY have recordings of people in the driveway or cars driving by. It is definitely sensing the cars driving by as in the video above. I haven't noticed any difference on cloudy days but we've only had a couple since I turned on PIR.
Are you sure about PIR having that short range?

Ummmm, yeah.

16.4ft or 5m.

Oops fixed the post above.
IR illumination and PIR are two separate things. The cam has a IR illuminator that shines IR light so the cameras lens can see in darkness. This illuminators throw is 16ft. This is because it is only one illuminators and not very strong. It is to the right of the main lens at about 4 o'clock.
The PIR sensor is the big dome directly under the lens and doesn't use the actual lens. I haven't found any specs on the distance it can sense heat signatures

Open the use manual. The PIR is the same as the ir in the specs

You are correct!
But it is definitely sensing cars in the street. It doesn't detect people on the sidewalk so maybe it's the large heat signature of the cars.
