Our Wisenet camera system was destroyed by lightning and we decided to search Amazon for a replacement. I had purchased a few ZOSI cameras for our old system and was pleased with the quality. The new system from ZOSI arrived in a couple of days and was easily installed. The packaging of the product was fantastic. The system is easy to set up and customize and the app has worked flawlessly. We did have an issue with the system restarting several times a day, but I reached out to customer service and they emailed me a link to download an update for the system. This fixed our problem, but had it not they were going to replace the Dvr. Apparently this is a known issue and is easily fixed. Very satisfied with our purchase. Great system great price.

I have used this camera only in analog mode, and only over a short time. It seems to give excellent video results in that mode. The 36 IR LEDs give adequate night illumination for the useful viewing area of the wide-angle lens, while not "washing-out" nearby objects. I normally don't use cameras having this wide a viewing area, but the usual negative aspects of wide-angle lenses are not much of a problem in the case of this camera. (Not sure if this camera has some sort of electronic or optical compensation for the wide-angle effects, but in any case, it seems to avoid or reduce those effects compared to other wide-angle cameras that I've used).The physical disadvantages (for me) include:- The black and white colors of the camera's housing seem to make it relatively conspicuous as compared to single-color housings. (I suppose this could be a good thing from the perspective of deterrence, but not if the objective is to be unobtrusive).- The "visor" - which is too small to be very functional anyway - is non-adjustable (because it is simply a sculpted part of the housing). This is a problem if an actual adjustable visor is needed to protect the lens from dirt, rain, snow, etc. and/or to shield the lens from a spurious light source.- The camera housing is slightly more compact than "average", but not nearly as compact as some cameras.- The front housing appears to be relatively difficult to remove - and probably would require the camera to be dismounted to open the housing - which would be a problem if any fine focus adjustments are needed "on the fly".- The mounting/aiming "mechanism" is the fairly typical "2-locking screws plus one locking ring" arrangement, which "sort of" gives three axes of adjustability but is fairly difficult to adjust and lock-in - especially when working from a ladder. While it is a better arrangement than some mounts, it is much more difficult to adjust than the tool-less "single ball with locking ring" universal arrangement that has appeared on a few camera housings.Bottom line: This is a functionally very good camera hampered by a mediocre housing design.

These basic CCTV cameras work well enough for daytime use, not that good at night or dark rooms period. Easy to install and connect to most CCTV units. Hard to get these into color videos and always black and white. But still a decent basic CCTV camera for home CCTV security systems. 4 stars.

I select Zosi to replace a 5 years old legacy home security system with low image quality and constantly false alarm . After finishing installing and used it for 2 week, I have to say Zosi has not disappointed me at all.At the beginning, I did experienced some connectivity problems due to the wiring method of the legacy system. Luckily, Zosi’s customers support was very helpful with prompt responses. After the initial problem was solved, the rest of the hardware installation was just plug-and-go pretty straightforward.Zosi’ mobile device control functions are a bit limited. Most of the setup works need to be done in the NVR box. The user interface was OK but could be more user friendly. The entire software setup and camera testing work was a bit longer than expected. However, Once it is done, the system’s performance was very impressive! - crystal clear image with no more false alarm. Highly recommend!!!During the entire installation process, there are a few things I don’t like and would like to point out :1. Humanoid tracking was not installed in the NVR system nor in the cameras. Customers need to do the upgrade on sit. This is quite surprising for customers buying a brand new product.2. Systems upgrade can be done relatively easily but the camera upgrades was a bit more complicated.3. The response time of the tracking system could be faster.4. The cover material for C296 camera is plastic. Don’t know how long it can last outdoor.
