..............This seems to be a problem that is systemic with this product, as is the "non-response" from customer service !!!
They have been told numerous times about this design flaw, and choose to ignore it, and their "customers"!
I personally feel the night vision issue is more to do with the intensity of IR lights than the actual camera sensor. Netgear might have chosen a less intense IR illuminator for Arlo Pro 2 to save on battery charge. If this is the case, I don't see how any update will fix the issue. A 3rd party IR illuminator will, but whether that is ideal or not is for one to decide him/herself.
Tendelux 80ft IR Illuminator | AI4 No Hot Spot Wide Angle Infrared Light for Security Camera (w/ Power Adapter 20 bucks .this will turn a pitch black yard into one that looks like daytime
...........You make a good point!! I noticed the IR brightness seemed lower than previous models I have used. If this is the case, it kind of confirms they brought to market a "flawed" model !!
I bought the Arlo Pro 2 two-camera package over the weekend. I put one on my front porch, one on my rear deck.
The one on the front porch is powered, and fine.
The one on the rear deck is on battery, and had great night vision for about two days.
Then, suddenly, all the night vision shots are faint and washed out.
Swap the cameras around to see if the problem stays with the camera. ALso, was there previously external lighting for the deck that's now off?
