ZOSI 1080P 8CH CCTV DVR Recorder with AI Human/Vehicle Detection, 8 Channel 2MP 1080p H.265+ Hybrid 4-in-1 Home Surveillance Wired DVR for HD-TVI/CVI/CVBS/AHD Analog Security Camera (No Hard Drive)

I bought this to replace a lightning fried Cobra security DVR that I purchased 3 years ago from Harbor Freight. I was able to save my old hard drive and installed it easily, then connected my existing wired cameras and monitor. Up and running after a quick set up and hard drive format. I downloaded their app to view the cameras while out of the home and it worked perfectly. Although picture quality isn't the best while viewing it this way, it was incredibly easy to access. My old Cobra system was a nightmare to view remotely, having to use ddns, port forwarding and a smart plug with remote access (it needed to be constantly restarted to connect). I then tried to view on my Windows laptop and here is when the hiccup came. I downloaded the AVSS software and followed the instructions, logging in to my account. My device showed up but it's status was "offline" and when I clicked the channels to play nothing happened. I tried a bunch of different things (opened ports, deployed web AVSS launcher) but nope, still showed offline. I finally contacted Zosi email support and provided everything I could think of. I received a surprisingly fast response from "Jar" with a simple fix. He suggested that I choose a channel from the device, right click it and hit play. I doubted it would work since the device was still showing as offline, but I followed his direction and it worked! All of a sudden the device was showing "online" and I was able to view my camera (low quality, but still.....). I did the same thing with each feed and they all worked. Nice job, Jar!

After doing extensive research and comparing various DVR options, I decided to go with the ZOSI 3K Lite 8CH CCTV DVR Recorder, and I'm genuinely impressed with what it offers—especially at this price point. I’ve been using it for about a month now, and here’s my honest experience so far: ✅ Setup and Compatibility Even though I’m not a tech expert, setup was straightforward. The unit came well-packaged with clear instructions. I already had a few older analog cameras (TVI and AHD formats), and I was relieved to see how easily they worked with this DVR. It’s truly plug-and-play for supported camera formats. Just remember: this model doesn’t come with a hard drive, so you’ll need to install your own (I added a 1TB WD Purple drive without any issues). 🔍 Video Quality & AI Detection The video output is clean and crisp—significantly better than my previous DVR system. While it supports up to 3K resolution, my existing 1080p cameras look fantastic, especially with the H.265+ compression, which saves a lot of space on the hard drive without compromising video quality. The standout feature for me is the AI Human/Vehicle detection. This drastically cuts down on false alerts (like animals, shadows, or blowing trees). I have it set to notify me when a person or vehicle is detected on specific cameras, and it’s been very accurate. No more sifting through hours of useless footage! 📱 App and Remote Access The ZOSI Smart app is solid—basic, but reliable. I can easily check live footage or play back recordings from my phone. Setup was easy with the QR code pairing. Remote viewing works even on slower mobile data, which is a big plus. There’s also the option to configure alerts and playback via browser or their desktop software, which I’ve used a few times. 💡 Other Notable Features Hybrid 4-in-1 Support: This unit supports HD-TVI, CVI, AHD, and CVBS—perfect for those who are mixing different types of analog cameras. Motion Zones & Schedules: I appreciate the customization—motion zones can be drawn manually, and you can set schedules for each camera. I’ve set mine to only record during nighttime hours for certain zones. Build Quality: The DVR itself feels well-made and doesn’t overheat or make noticeable noise. ⚠️ A Few Things to Note: No hard drive included, so factor that into your budget. Not compatible with IP cameras (this is strictly for analog camera systems). The user interface is a bit dated, but it gets the job done. ⭐ Final Verdict: If you’re upgrading an older analog system or building a custom wired setup from scratch, the ZOSI 3K Lite 8CH DVR is a rock-solid choice. The AI detection is surprisingly good for the price, and the overall system is reliable, customizable, and user-friendly. Once you add a quality HDD and your preferred cameras, you’re looking at a powerful DIY home security solution at a fraction of the cost of full-package systems. Highly recommended!

This is actually my third time buying this ZOSI DVR, so that says a lot. It’s been reliable for me, the video quality is clear, and setup is pretty straightforward. I like that it has good compatibility with my cameras, the connectivity is stable, and the storage capacity is great for keeping recordings without constantly worrying about space. The AI features also make it feel more updated and useful. The only downside is that after a few years of use, I’ve noticed the DVR can start acting up or stop working if you don’t keep up with updates. Still, overall it’s been a solid system and I keep coming back to it because it does the job well.

Very good close circuit TV system. The mobile app sucks though.

After 6 months it stopped recording and this whatee shows up this is the second time i have had to purchase cause it stopped working. Anyone having issues like that

Along with Zosi quality and affordable cameras, this DVR is the way to go! It does not come with a Hard Drive, but if you’ve ever changed a computer hard drive, you can easily install your own instead of paying more to buy one already installed. Its just 4 screws to open the box, then use the screws that come with the hard drive to connect and place firmly inside the DVR. I installed a Seagate 1 TB Hard Drive and it works perfectly. Once installed and plugged in, the DVR automatically formats your hard drive and installs the software. You don’t need more than 1 TB as this DVR stores around a month’s worth of footage before automatically rewriting over the beginning of older footage. Also, don’t forget your passwords once you set them in the DVR. If you do forget your passwords, you won’t be able to reset the DVR to factory settings like most other devices. You will either need to contact customer service or update the firmware. Every time you update the firmware from a USB flash drive on this unit, it automatically factory resets everything and deletes all older settings. Also, you’ll need to download the ZosiSmart app to monitor your system while away from home and your DVR will need to be plugged into your home internet connection through Ethernet. The instructions are vague, but what products don’t have vague instructions that are made in China. What matters is this is a quality system that works! Highly recommend for someone that needs a security system on a budget!

I am a big fan of Zosi (cameras are the best!) until I tried to view CCTV feeds on our home network. Before purchasing the Zosi DVRs, I asked if Internet was needed and got the answer back as "NO." I ordered 2 DVRs to go with Zosi cameras we had just added to our Lamb birthing barns. On DVR-arrival I find the "NO," answer to be only partially correct. You do not need Internet to view the cameras when a monitor is plugged directly into the HDMI port of this DVR box. However, if you want to see the CCTV video stream on your home network then you must download and install the app on phone or PC. I am OK with that install-app part, but then, the Internet must be live for viewing our CCTV feed. Would we be sharing that CCTV feed with the Zosi servers? I do not know, but I do question why they would need the Internet for **only** us to view our private camera feeds. That ain't happening in this household. Our CCTV feed stays here so I bought a different brand (ASIN B00GB1IHSY). This one is about the same price and functionality. It does **not** require live Internet for local network viewing with their app on the network PC that never sees the Internet. Caveat Emptor.

This is a very good dvr for the price. It does not come with a hard drive, but that is ok since we always purchase them separate anyway. The features are ok, but you will need to look up the manual online for some of the more advanced features. The company is good about releasing firmware updates, but you do have to manually install them with a flash drive. This dvr is called a 4 in 1 unit which means it currently takes 4 of the mainstream cameras. You can mix and match if needed. The remote app is ok. It works and is a little buggy but it does what it is supposed to do. Overall this is a great buy with good features and a good warranty. We use it in residential and commercial environments.
