ZOSI 1080P 4 Pack HD TVI Security Cameras, 80ft Night Vision, Outdoor Indoor Weatherproof Bullet Camera for 1080P/5MP/4K HD TVI Analog CCTV DVR System

Why did you pick this product vs others?:Picture quality is great, definitely a very good investment for your home or business. I would recommend these cameras to everyone.

Easy set up, clarity and great night vision, more bang for your buck!!

Got these for some blind spots on our system. They have great picture and the quality of wires didnt fail on tention.

Here’s the quick and dirty if you don’t want to read the wall of text that follows:Cameras: 5/5 - Look great, easy to install, good infrared, great picture. Honestly, the price of this system as a wholeDVR: 3/5 - Easy to install, had many issues, Zosi sent a replacement.App: 2/5 - Secu365 is the only app our original system could use. It’s not very intuitive, but it did what it needed to do.Zosi Customer Support: 5/5 - Incredibly helpful, would buy products from Zosi knowing that they will try and get your situation fixed if they can. If not and you’re under warranty, they’ll send you a new one. Props specifically to Moon from the support team – you were WONDERFUL to work with.Overall recommendation: 4/5 - There are better systems available, but probably not for the price.___________________________________________________I bought this system in July of 2017. It was on super sale at the time, and nothing else in Amazon's stock was quite as versatile as this system was, so we opted to buy it.The setup was very easy and rather intuitive - it's the first system I've ever set up by myself. The user interface is less intuitive than the hardware installation, but it's certainly navigable and adequate. It's a bit of a chore to set up multiple users using the virtual keyboard, but the unit comes with a USB optical mouse that needs no installation beyond plugging it in.The cameras are of excellent quality and have already withstood a Michigan winter with nothing to show, all camera functionality was flawless during the cold and wet. The infrared has quite a good range with the added bonus of showing red lights surrounding the lens when it is on - I think this is a useful deterrent showing your neighbors that there are cameras recording. One thing to note upon installation is that the cable can unfortunately be installed backwards, so make sure that you are hanging the wire the correct direction.With the cameras being as good as they are, I would have hoped the DVR would match. However, we had issues that began appearing around December. We noticed that the App (Secu365) would send back a "system offline" message when attempting to view, so I went to check the DVR. The cameras still had a live feed displaying on the monitor, but it was not recording and NOTHING could get the DVR to respond. I "fixed" this by unplugging the unit and waiting a few minutes before plugging it back in, at which point it appeared to function normally. I thought this was because our DVR had been in the cold garage, so I moved it into our basement where it would not be in freezing temperatures. This did not fix the problem, so I contacted Zosi support.Zosi told me that my system needed to update, which was true! There had been an update that went out, but I didn’t ever think to check for anything before and I think this contributed to its demise. After the update, the system functioned normally for about a month and then went right back to the freezing issues. The DVR got worse, and eventually simply plugging the unit back in would not make it turn on. I had to plug and unplug repeatedly, listening to it beep as it ALMOST turned on, but never finished. Eventually, after getting it to power on, the system would function normally for about 3-6 hours, and then it would freeze. I was in contact with Zosi trying to come up with solutions, and eventually they sent me a new unit.I installed the replacement unit yesterday at the time of this writing, and it is functioning as it should so far! This review shall remain in its current state so long as everything remains working well.

They work good as expected.

Great picture

This is a decent beginner DVR. Easy to set up, easy to swap and install HDDs, and the software is easy to understand.I really like the unit for the price, however, i have had numerous issues with playback errors which requires me to restart the DVR. I get errors that say something like 'you can only playback on one device at a time, even though i am the only one accessing the DVR.I also ran into an issue recently where i was required by police (due to a shooting across the street) to save a portion of the recording (one full day) and the DVR would not allow me to. I plugged in an empty flash drive with plenty of space and I even tried different reformatting to a few different formats (exfat, fat32, NTFS, anything i was able to format it to) and i was unable to. The only option was to playback the entire day on my PC and screencap it (13 whole hours i couldnt use my PC)I work in IT, im familiar with most types of technology, and i tried looking for a solution, but the DVR was not operating as it was supposed to, and for that reason i will be looking for a new DVR soon.
