ZOSI 3K Lite 8CH CCTV DVR Recorder with AI Human/Vehicle Detection, 8 Channel 1080p H.265+ Hybrid 4-in-1 Home Surveillance Wired DVR for HD-TVI/CVI/CVBS/AHD Analog Security Camera (No Hard Drive)

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 CompatibilityEven 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 DetectionThe 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 AccessThe 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 FeaturesHybrid 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 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.

Recently bought in February 2025 and it already stopped working May 20205 I had problems with the hard drive the dvr couldn’t read it anymore so nothing is being recorded can’t even go back and look at past recordings. I contacted customer support tried everything they told and nothing help resolve the issue the hard drive is basically dead but they won’t send you a replacement they basically told me if I had another hard drive to use that and they closed my request. So I don’t recommend you waste your money on this garbage it’s not a reliable dvr to buy.

This camera set works, but don't expect it to last long. I've bought three of them, and none have lasted more than two years, but I'm happy with the cost/benefit ratio overall. The DVR is very easy to replace as long as you already have the cameras installed.Considering the price, I'm happy with the UI.The app for viewing the cameras from your phone sucks, and I'm not sure I should trust that no one else can access the cameras, so I keep mine disconnected from the internet.

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!
