A 2.4K security system consisting of 4 cameras, a base and a memory card. The cameras are 3 mega-pixil and have an aluminum housing which can be used indoors or outdoors. The system has automatic human detection for better security. Two way audio is supported and the ZOSI APP allows control and monitoring on your cell phone. You can use a hard drive or SD card for encripted storage. Overall, a well made and durable security system.

If you have power and have a wireless signal for the main head unit, you have a quick and easy wireless camera system. This took me about 45 minutes from unboxing to being fully up and running, and that included screwing the cameras up around the front carport. The head unit is in the garage, and everything is working perfectly, although I needed to move the main unit around to make sure all the cameras hold a steady signal - Not the most powerful I have used.They aren't HD cameras, so don't expect full facial recognition, but they do a great job for the price. The only thing I haven't been able to figure out yet is turning off the built-in speaker in the head unit. If you say anything within range of the cameras, your voice is echoed inside the garage. There is no way to turn that off within the app. I want it to record sound, but I certainly don't want it broadcasting in real-time 24/7.

Being able to see what's going on around your home, business, etc. is desirable for many people. However, some may not have this 'luxury' due to the time, effort and/or cost involved. This system is, at least, partially wireless and, potentially, much easier to install. Not to mention fairly cost-effective. So, it was ordered as a gift for a family planning to move into a new house around Thanksgiving.The package arrived, double-boxed and without obvious damage, in 2 days. Which matched the delivery estimate.First, the included documentation is sparse and generic.As I mentioned, this system's video and audio can be transmitted wirelessly. However, the the DVR (main unit) and four cameras require electrical power. Each device comes with an AC adapter. The camera adapters have DC cords which around 10 feet long. They appear to employ the common 5.5 x 2.1mm power connectors. Which would allow them to be extended via extension cables designed for this purpose.The camera bodies are 3-1/2" wide, 2-1/4" thick and 3" front-to-back. So, they are relatively small. Including their mounting brackets, they can be as much as 6" long overall. The white camera cables are about 18" long and terminate in female connectors for both ethernet and power wiring. Thus, they can be used via a wired or wireless Wi-Fi connection. Based on my examination of the cameras, it appears that the cables are permanently attached and incorporated into their mounting brackets. If so, the brackets may not be able to be be removed.The field-of-view for security cameras is an important consideration. The label on the cameras shows their model number is ZG3023M. (The Zosi website lists a ZG3022A camera which looks to be identical.) However, based on appearance and other factors, my guess is that the four cameras in this system are what Zosi refers to (on Amazon) as ZOSI Wi-Fi 6 add on Camera. (No model number is shown for it.)If so, this link may be of interest: https://www.amazon.com/dp/B0DW7NWRTGThat link shows a 90° field-of-view for those cameras which is adequate for most needs. But, bear in mind, that is what is generally known as a wide-angle lens. As such, it is more likely to provide WHAT and WHEN information and less likely to provide WHO information. Especially when it comes to reading license plates.The DVR (NVR in this case, I suppose) is small and rather simplistic. It relies on an SD card for storage and has no hard drive. Although, a kit to convert the unit to use a hard drive is mentioned.This system is OK, I suppose. But, honestly, I prefer a manufacturer to supply more nuts and bolts info and less glitz/glamor stuff. More model numbers, specifications, in-depth manuals, etc.By the way, C302 seems to be the model number for this system. Using that number, I was able to find the specs for what I believe is the NVR in this system. The specs indicate it has an SATA interface and can support drives as large as 8TB. Additionally, there is an installation video on their zositech website in the MANUAL tab on the C302 page.I am rating it as 4-stars but only because it is complete and appears to be as described. I absolutely despise having to put this much effort into finding basic details about a product. It is maddening and totally unnecessary. Zosi really needs to step it up in that regard.

This is a pretty straight forward system. It’s easy to install the cameras and the interface is easy to navigate. The picture is clear and the included memory card is nice but I recommend picking up a bigger one.

6 cameras, a monitor, and a card for keep all the activity at your home and business secure. 6 cameras with AI intelligence. Night and Day security. Recording available and play back. This is a great security Camera System set up. Comes with everything you need for setting up right away.

This is a good budget friendly security system. The HD cameras have good image quality. They are wireless and only need to be plugged in to an outlet. The recorder is small and stores video to a budget friendly media option that makes it very easy to swap and transfer important footage to your PC/Mac. It is easy to setup and the app makes remote viewing possible from anywhere.
