If you want the equivalent of a "Bose System" sound machine to put you to sleep this is it.As an engineer, I've been involved with noise measurement studies, the effects of noise, and, in particular, the psychological impact. Living a block from a train station, I take it personally. Before receiving the device, I was a bit concerned by the adaptive aspect (which you can turn off) where it gets louder when it "hears" loud background noises -- such as a train whistle in the middle of the night. However, in fact, it does work well to cover over the disruptive sounds.Part of the function of this device is to distract by increasing the little background noises such as insects, foghorns, bells etc. Fortunately, you can change the levels depending upon your personal preference. I thought I'd prefer the simpler sound, when, in fact, after a little experimentation I actually now prefer the highest level of "reality".What also separates this machine from the others that I've tried is the quality of the sounds. They're not harsh, tinny, electronically produced sounds but apparently recordings of live sounds. With the cheap machines, one quickly becomes aware of the looping aspect of the sounds, that is much less noticeable with this machine. The device is comparable to a small, quality table radio and has relatively rich bass tones.During the warranty period, I did have one problem: it wouldn't turn on. I called the company and was helpfully talked through the "rebooting process" which took all of 20 seconds. The problem hasn't occurred again; and I was offered an additional year of warranty from the time of the problem, which I consider more than fair.

The V3s have far superior night vision than the V2s, I don't even use the IR on the new cams which is great because the IRs attract insects, which attract spiders, which build webs all over the cams. The picture is a lot better and the motion sensing seems to be much improved. The only downside is that the microphones on the new cams suck, I don't even use them because all I ever hear is static. The mics on the old cams were a lot better. If not for that would have given 5 stars.

Wow! First off this is not a cheap light, luckily I managed to get one on sale for $256. I bought this lamp to light up my work area where I stretch insects. Previously I've used portable LED lights in various configurations which were just crap. This lamp produces nice soft light and has a good spread. I have no issues with the build quality. The jury is still out on the "ring" on/off switch which might have been better suited to a slip or rocker switch. All in, very happy with the lamp and quality of the light.

if this review is "vine" labeled let me reassure you, this was a bonafide purchase! i've been using reolink for over 7 years. in the last 10 - 12 months or so, i decided to take advantage of a sale and upgraded my rln8-410 nvr to the latest version, n2mb02. lemme tell, u - a HUGE difference with noise and more features to boot! the old one had a ridiculously noisy fan from day one and ours was in a cabinet with a door! the new one is whisper quiet. whew, what a relief! so on to the cam but realize that you will need the newer nvr to take full advantage of the duo 2's feature set.after upgrading the nvr, i decided to try the 5mp (rlc-510a) cam. the originals were 4mp (rlc-410). so while running both on the same new nvr, the video was noticeably clearer, and the mage detection settings were much improved. so yeah, i ended up replacing all the 4mp cams. well worth it.there was one spot where i was missing coverage without adding an additional cam. have the installer come back out to add 1 additional wire was an expense i wanted to avoid - not to mention the mess. back then, the duo had come out but the reviews were subpar. so i waited.i bought this duo 2 yesterday (yeah i know, finally, right) and WOW! where my others are now 5mp this is a 6mp and the difference is exceptional. didn't think it was possible to have this type of clarity at 11pm! during the day, the difference is not as noticeable. the "stitching" is well done although, there's a noticeable difference in shading at night. if it's there during the day, it's imperceptible. mind you, i also installed the latest - ...91900 (sep '22) firmware.duo 2 comes with more settings and one that i especially like is the spotlight. in auto mode, when motion is detected, bright 6000k light illuminates then after some duration, it goes back off. look folks, i don't work for reolink but this duo 2 is so good, it actually, showed images in color at 11pm where the other 5mp cams just showed b/w. so yeah, i'm a fan.the install was a piece of cake. while it has 2 cams, it only uses 1 rj-45 cable for power and digital signal when connected to the reolink nvr. my wires are in the eaves but i installed the weather-proof fittings this go round. should've done it with the others too but...cons:1) when using the windows client app, you will see black horizontal bars above and below the image and2) when suspended, the bracket needs to allow for a higher angle other than 90 degrees - perhaps 145, so if you want it pointing down more towards the ground. the good news is that it has a wide enough angle to compensate some, but you will see lots of sky.i'm still playing with the adjustments on all of the cams. they are configured to record for motion but can be very, very sensitive. the duo 2 would actually, record flying insects in the dark, till i tweaked the setting down a tad. that's some terrific sensitivity if needed. so yeah, quite pleased.
