So I guess even with it set to dusk it isn’t switching to night mode automatically for some reason. The pulsing is the color night vision trying to adjust. Did you give it a couple minutes to see if it switched (it takes a bit to “decide”)?
When it is purple, is it totally dark in the garage? I wonder if there may be some small light somewhere making it think there is enough ambient light. Even possibly the IR that runs across the garage door for the safety sensors. Could potentially try tilting the camera down and/or to one side or the other, I wonder if the track for the door is somehow confusing it.
May just have to try replacing the cam, if it isn’t automatically switching to night mode when it is dark I’m wondering if there is some calibration in it that is off.
I have a couple battery chargers with small status lights located behind the camera and blocked by the car.
I left the night vision set to auto and noticed this morning the purple was gone and the video is black and white, so I reviewed last night’s footage and saw that after a couple minutes the pulsing stopped and went to solid purple. After 10 more minutes, the night vision kicked in and the video was clear black and white.
I’ve already ordered a replacement from Amazon and I’ll see how that goes. Also, if I’m not too lazy, I’ll try swapping out one of my other v3 cameras and see how they behave.
How about leaving Night Vision completely Off? You could try a couple of LED night lights plugged in around your garage to see how video looks when the sun goes down. Here are 6 night lights for $6.99.
Yeah it seems like something in the cam is not sensitive enough. The people in that other thread wanted it to stay in color night vision mode but were getting the purple hue when there was ambient light. Their issue was not that it wasn’t making the automatic switch.
I think that’s a reasonable next step. I’m wondering if that pulsating (calibrating) is tricking the cam into thinking there is ambient light, and once it finally settles down it makes the switch. I think that cam is just not calibrated properly, or maybe the image sensor is no good. For reference, I have an OG in a front stairway that is usually dark, when I turn on the light it switches out of night mode within a few seconds, and when I turn it off it switches back within a few seconds.
I have a Panv3 in my driveway also that late at night once all the lights are off it switches, and the transition is smooth. This does seem to be a (non pan) v3 specific issue but what you’re seeing I believe is the combination of two problems - purple hue when light level gets low (known), plus a long delay in switching (hopefully just a bug with that specific cam).
I see there’s something white under the camera, I had a similar problem that a white light fixture caused the camera to bleach out. I was able to fix mine by re-aiming the camera, you might temporarily cover that white object with dark construction paper to see if it clears up.
My 2 floodlight pros exhibit this problem on occasion. One had the purple tint last night. I used to just repeatedly switch “Night Vision Mode” between “Auto”/“On”/“Off” to fix it. I had to restart because it didn’t work this time.
