Summary: I purchased this in hopes of fulfilling a wireless camera solution. I purchased 6 of GrandStreams bullet style HD cameras and they were great, so thought I would give this a shot. The image quality is good...when it worked. I think WiFi security is still pretty new. The video would keep skipping and even hang. I reduced the frames per second to near 5...then 1...and it sill produced a bad quality feed. Not sure where you would use this but I couldn't find one.
Summary: I bought this camera about a year ago and I use it with Blue Iris software. I am quite impressed with the picture for a sub $100 camera. (see image). The only quirk I found is that if I set the resolution to 800x592 instead of full HD, I actually capture more image. The full HD zooms in to fill the sides and ends up cutting off the top and bottom. I will buy more of these where night viewing isn't a concern as this camera has no low light mode.
Summary: Spend a hundred bucks more and get a real camera I bought it once and it was DOA after calling Grandstream it was a nightmare because they do not do direct RMA's so I had to contact the reseller who (out of his kindness) sent me a new unit. But Grandstream's support is terrible, save yourself the headache.
Summary: This is a great camera for me. I use it to look through a window with screen to the outdoors (so no IR, or ability to turn off critical), and it sits between window & shade, so thin cube form factor great, and white color of unit not obvious. No worries about rain/snow/weather when placed like this, and I have outdoor motion sensor spot lights for night lighting in this area (though with .5 lux, it's still not fantastic at night) .
Summary: On a wired connection, the image quality in good lightning is superior to the non HD version. The configuration screens are very slugish. Reduce the lighting and the camera does not increase brightness to compensate. You can adjust it manualy to get acceptable image but that does not work in a changing environment. Wireless: I have two GXV3615W cameras (non HD versions) working on my wireless with WPA2.
Summary: I got it configured in Synology Server under GrandStream GXV3615, Video format: H.264 and Audio: G711, resolution 720 * 576, Frame Rate: 25. But actually I set it up in camera server as 1600 by 1200. So it's streaming 1600 by 1200 to my server at 200k-300k/second with no problem. The setup is a breeze, just connect to Ethernet to set up WIFI, disconnect Ethernet cable then u are done. It find WIFI much quickly then the IP cameras I had before and excellent video quality.
Summary: As a camera it is great value for the money. Great resolution and a nice compact size. POE capable and has focus adjustments. good build quality and pretty good firmware. don't buy it for the sip features as I think it was a horribly engineered afterthought. speaker level is so low I question if the engineers were high when they designed it. otherwise better then the 99% of its peers in this price range.
