Re: Arlo Pro 2 Flashes Of Light At Night
HW version H3 Serial number 5TF18A71CCEE6 Firmware 126.96.36.199_29092 Night Vision ==ON Plastic removed from camera front Both cameras mounted outside (1 has no ambient light whatsoever) Both cameras on battery Daytime presentation is excellent, however at night, either in motion detection mode or LIVE continuous flashes of light literally obliterating the presentation. I see other users with pictures I would be very happy with, so do I have two defective cameras or something I’ve overlooked?
These two pics I saved from last night don't really represent how bad the presentation is. The one in the backyard atually caught two coyotes that wandered by that I looked and looked at the video and finally found them from their reflective eyes. In LIVE mode it's a continues stream of flashing smears.
Right Guru...had deleted the old files so here is a new one I created this morning. I tried playing with the brightness setting but using the chrome browser in LIVE mode it took me several minutes to just get it back to zero. The slider does not follow the mouse properly. Cannot get it above zero and under camera settings the brightness icon is not active (greyed out). Very frustrated.
Ok, that video was VERY descriptive and not at all what I expected to see. It appears to be a swarm of bugs reflecting the IR from the night vision LEDs.
The brightness control is not smoothly varying. It has distinct stops - a total of 5.
After much patience set both cameras to +1 brightness. Here is a video from the back of the house camera with no ambient light. There are 6 LEDs at the top of the camera (inverted U pattern) with 2 bright and 4 dimmer, plus 2 more bright LEDs in the middle of the camera (side-by-side) for a total of 8. Is this this a correct layout for the LEDs?
Maybe my question was not clear - should the 6 LEDs on the top of the camera all be of equal brightness? I have 2 bright and 4 dim. The 2 LEDs to either side of the lense itself are bright for a total of 8...4 bright 4 dim.
If you attempted to post a link or image, it didn't work.
It's still light out so can't check a camera but as I recall, all LEDs are the same brightness. I suppose it's possible that some are angled so you have to change the angle you're using to look at the LEDs to verify that they're truly changed or maybe reducing the brightness also changes the amount of IR light from the LEDs. Try a different camera and change the brightness as well to test.
I tried several times to share/copy link from the libraries, but it just isn't workng today (nothing to paste) so I downloaded the video file then attempted to attach it but that didn't succeed either. Anyway it's exactly the same as the 'front' camera insofar as the night flares and flashing. Crazy! Both cameras have two bright lights to the left and right of the lense, but among the six at the top 2 are bright and 4 are dim regardless the angle viewed. If you could check yours tonight that would be great. Unfortunately I think both of mine are defective...a shame since the daytime presentation is brilliant. I just tried to share again which failed so I'll try 'Choose File' again - but not hopeful.
I may well be blind (my wife says so) but I see 2 LEDs slightly below and to the left and right of the lens plus 4 at the top. All seem to be the same relative brightness.
Good morning Guru,
Thanks for looking last night...very kind. Do you have a pro or pro 2 because I see something a bit different. I have 6 at the top and 2 left/right of the lense. Looking at the camera without any angle 2 at the top and the 2 below are bright and form a rectangle of brightness (almost a square). The other 4 at the top present themselves differently. 1 on the left when viewed from a right angle becomes brighter, and 1 on the right when viewed from the left becomes brighter. 2 at the very top when viewed from an angle lower become brighter. So it appears 4 of the lights at the top are set at various angles to disperse the IR accordingly. The source of the distortion is fog. Here in the Rogue Valley, OR we get a lot of fog. Early last night before the fog the IR refraction was not present, then this morning with fog quite bad again. I would rate the image without fog moderate to poor, and with fog useless. Looked at various video clips of IR cameras through fog and although the results vary none are as bad as the arlo pro 2. So guess I need to decide whether to live with the flaw or send everything back. Shame as the daytime perfomance is brilliant.
I specifically looked at a Pro 2 to be sure. I could be wrong but I swear there were only 4 LEDs at the top, all of the same brightness. I suppose it's possible you have a newer hardware revision (mine is H3).
Have you considered external lights? There are various IR spotlights listed on Amazon for 850nM, some with motion detection, and there's always a regular motion activated outdoor light. On some of my cameras I've added an Arlo light which works well and could be useful for you, especially if using different angles helps.
H3 - same as yours and nope - 6 on top. I created an html diagram of the LEDs, but unable to attach as CHOOSE FILE doesn't work. SIGH!!!
So how does one configure camera SETTINGS if using an external IR source? I see CAMERA LED, but the heading under that is Battery Fully Charged Indicator. The manual points to the LED to the right of the lense and states they change color? Meaning when the battery is low? I think NIGHT VISION turns OFF the LEDs altogether. When night vision is enabled, the camera automatically turns on infrared (IR) LEDs to record in low light conditions. We recommend that you turn off night vision if the Arlo Pro 2 camera is facing reflective surfaces, such as windows.

Just rechecked my P2 and see 4 LEDs on the top with 2 others, one on each side, just below the top 4 so your observation seems to be the same. I had to move around a bit to make sure I wasn't seeing a reflection or refraction but I now agree that there are 6 on top with two slightly below the level of the lens.
As for external lighting, that's totally separate from Arlo - there's no setting. You just add lighting and configure as appropriate.
Right, of the 6 on top 2 are very bright (when viewed straightaway).
The built-in LEDs have the same issue as driving in fog/snow with you headlights on - bounces right back into your vision. An offset source would minimize that effect and can be stronger so you get a better view of what's going on at a farther distance.
The Pro has better night vision primarily due to the pixel size of the sensor. Each increase in resolution but the same size sensor results in smaller pixel sizes and, hence, fewer photons hitting each cell. You can increase the sensitivity of each cell but then that also increases the background noise level at the same time, reducing the overall quality. Additional lighting of any sort eliminates the issue which maintaining the increased resolution of the P2.
Driving in fog: True, but I have viewed other IR cameras and whereas they exhibit haze etc. haven't seen anything as bad as the arlo pro 2 in fog. If resolution is the issue at 1080p then perhaps the arlo pro 3 will have two lenses, one for daytime and a 720p lense that is switched to when the LEDs turn on. I'm going to keep these and perhaps add a plain old 800 lumen LED non IR battery powered external light with a motion detector. Thanks for your help Guru!!!
