The ZOSI systems are quality products.Three years ago I installed the name brand system (with the owl face) in my home and at the same time I installed a less expensive ZOSI system in my daughter's home. During those three years my name brand has given me fits, usually disconnecting the app and needing a reboot to get back online. That happened frequently, but usually on the first day of every vacation, leaving me unable to monitor my home. Meanwhile, my daughter's ZOSI has never once failed to connect, even after three years.With 4K becoming more mainstream, I decided to upgrade and this time to the ZOSI. I was a little disappointed to see there were none here in the states, but it arrived from China in about 8 days. In about 20 minutes I had switched all the cables over to the new ZOSI DVR, then spent the afternoon switching 4 of my 8 cameras out to the new 4K cameras, and the evening getting all the DVR system set up the way I wanted it.I had just one item on the setup that I couldn't figure out, so I sent an email to the ZOSI tech support and about 10PM I received a reply with step-by-step instructions and about 8 screenshots to make everything clear. This solved my question in a few seconds.I now have the apps set up on all our mobile devices, my mac, and monitoring on one input of my TV and all with almost instant connection when I want it, whether on my LAN or away by internet. This system is well thought out and 1000% better than the old system I had.

Short story: OutstandingLong storyBackground: I started out with an 8-channel Zmodo DVR kit. The picture quality looked fine but I had nothing to compare it to. Later I upgraded the DVR section to a 16-channel DVR but with the original 8-cameras knowing I was going to expand the system in the future.After seeing so many customer photos of other DVR's I knew that the Zmodo had a low-quality picture so I purchased an Anran DVR and wow, what a miraculous improvement! It was like going from VHS to DVD all over again! Though the original cameras looked better, I was still dissatisfied.I began purchasing new cameras as upgrades with some pretty good improvements. But when I finally tried these Zosi 800TVL 960H cameras, I was astounded at the picture quality. Colors were accurately saturated, contrast was good, and the resolution seemed to match up with the Anran DVR very, very well. There is no mosquito noise in the system from low-light conditions either, which I definitely see on my remaining Zmodo cameras.Since the first Zosi camera, I have purchased 3 additional ones and have plans to purchase 5 more to complete the upgrades and expand the system as far as I want it. To be clear, I have purchased one of these white domes, a black dome, and a black bullet camera. All seem to have identical sensors, just different form factors and IR arrangements.These are so good, I might even replace some of my previously upgraded cameras.I was suspicious of the cost of the cameras, since most of the "good" cameras go for $30 or more (including 3 that I purchased before any of the Zosi cams), but these are shockingly good. Much better than my $30-$45 cameras.UPDATE: There is one flaw with this camera. If you angle the camera ball too close to 90° (90° means facing "straight out" instead of "straight down", 0°), the IR LED's will reflect off of the inside of the containment shroud back into the camera sensor which creates bright halos that complete drown out the image at night. I don't know if all dome cameras do that so I can't necessarily dock my rating of this one. Just wanted to make everyone aware of this limitation depending on how they intend to set the viewing angle. I'm simply going to use this camera in another location that faces more downward instead of outward and use a bullet camera in the location I need to "face outward". I suppose as an improvement, Zosi could coat the inside of the containment shroud with an IR absorbing material instead of an IR reflective material, but then the cost probably wouldn't be so spectacular at that point. Although, I could probably tackle that pretty easily as well. Maybe I'll try that and get back to you guys with another update.

This camera was easy to set up and the size is just right. The night vision could be improved but I like the brightness during the day time. The camera function great. The price is good for the camera

I have had this 8 camera system up and running for almost a year now. Cold winters and hot summers. Picture quality is very good, night vision is better than I expected. I did put a 1TB hard drive in it, and with 8 camera, it only stores 2 weeks of video. I would say a 4 TB hard drive would be recommended for people who are away from home for long periods of time.I like being able to sign in online and see my camera feeds from anywhere.I did notice that 1 of my cameras night vision is not working now, and this could be because it is the camera that is exposed to the highest winds and direct rain, snow, and hail.Overall this is a great system. It does need to be restated once in awhile, especially if there is a power outage.I will replace the 1 camera, because I am more than satisfied with the quality of Zosi.

Good camera very clear
