I have been actively using the Amcrest NVR model NV4232-EI for a few weeks, and I feel that I have a firm grasp on most of the overall functionality of the device.When I received it, it was packaged well. In addition to the NVR, Amcrest included a mouse, two SATA cables, some standard screws for mounting hard drives (not included), and a quick start guide. The quick start guide is comprehensive to get going, and to become acclimated with most of the device’s functionality. If you need additional information, a downloadable PDF manual is available on Amcrest’s web site.After installing a 4TB hard drive that I had, I powered on the device and performed the initial setup. I did so with the device connected to a monitor via an HDMI cable, using the mouse that was included. Set up was easy enough this way. Once I assigned the device a static address (not necessarily a requirement – but something I would advise) I opted to run the NVR “headless” and accessed it via the web interface.The web interface is largely the same as accessing the device directly. Navigating the interface is fairly simple, albeit with a slight learning curve. After spending an hour or so clicking through the functions and cross-referencing them in the quick start guide, I was able to put the guide away and make my way around without any issues.I have five Amcrest cameras around my home and property, all different models. The NVR detected all of them, and after I supplied their credentials, it was able to manage them fully. The Amcrest NVR is built for their cameras, and it mirrors nearly all of the functionality that is available within each camera’s own web interface. Any changes made to the camera in the NVR are updated on the camera itself.I set up two of my outdoor cameras to record continually, one outdoor and one indoor to record upon detection of humans-only, and one outdoor camera (which I use for weather) to never record. I can live view any/all of the cameras at the same time, which is really nice.Reviewing recorded footage is easily performed through the NVR’s “Search” function. Varying types of recorded activity can be reviewed through this interface. For example: it’s easy to review only “IVS” events on a camera that is continually recording footage by deselecting “General” recorded footage, so only the interesting footage and applicable time of recording is shown.Navigating through footage is quick, and can be done by clicking on the time index of the footage that you want to review. You can also have multiple cameras selected for this review, so you are able to see footage from different cameras at the same time index at the same time. This is a very nice feature to have. One thing that I was not able to find is the ability to playback recorded footage at an increased speed (for example, 2x, 4x, 8x, etc). I need to look through the manual to determine if this is possible.The human and vehicle detection features of the NVR work well, and the AI search feature makes it easy to search for these types of events in a given timeframe.The only challenge that I have had occurs with notifying me, via email, when a human is detected on one of my cameras. The NVR consistently sends me an email when a human detection occurs, but it does not consistently attach a picture. After some troubleshooting, I reached out to support, and they are working on the issue with me. It’s certainly not a deal breaker, as the footage is consistently recorded. More of a “nice to have” feature.Overall, I am quite pleased with this device. After a few days, I retired the use of my Synology Surveillance Station and now exclusively use the NV4232-EI NVR, as it has more features and it is built for this kind of use. If you are looking for an NVR that does what it is supposed to do, look no further.

I've been slowly replacing all my cameras with Amcrest ones and figured I should replace my aging NVR with an Amcrest one. This NVR is a highly capable and effective solution. The 4K resolution provides exceptional image clarity, and the integrated AI functionalities, including person and vehicle detection, significantly reduce false alerts. Power over Ethernet simplifies installation, while the intuitive interface and mobile application facilitate easy system management. Adding two drives gives ample storage capacity and ONVIF compatibility further enhance its versatility. While initial configuration may present a slight learning curve, the overall performance and feature set justify the investment. Highly recommended for those seeking a comprehensive and intelligent surveillance system.

If you have Amcrest cameras this is a great NVR. The ability to access it through the Amcrest Surveillance Pro app is very nice. It takes some time setting recording areas and sensitivity, but it should be a set it up and don't touch it, based on the experience I had with my 8 year old Amcrest NVR.

Disapointed. Unit failed in less than a year, 10 months to be precise. The internal Power supply for the Hard drive has failed. The unit can take upto 2 HDD but I'm only running 1 and it failed!

It is a fantastic NVR, easy to setup and use but my only problem is that i discovered some channels don't record while some other channels record.But i realized when I used Amcrest branded Cameras, they all record, but when mixed with other brands of Cameras, the Motion-detect recording problem occur in some channels and there will be no recording at all on the affected Channels.We don't have this problem with other brands except Amcrest. It happens on the 8-Channel, 16-Channel and 32-Channel NVRs.So if you intend to use other brand Cameras, then you must test your motion recording to be sure it is recording.

Here is my review for theAmcrest NV4232-EIPros:Easy setup as long as you follow the instructions - You MUST follow the included setup manual or you will go nutsVery clear display outMotion Detection works as expectedSelective recording was impressiveChoice between vga and hdmiGrid count options (I used 4)High capacity HDD compatibility for 2 drives (sata only)Easy camera detection during setup with (1) amcrest wifi camera and (1) amcrest PoESeamless connection with the Surveillance Pro 2 appPTZ controls are goodNice sleek, low profile look and not bulkyIncludes mouse and all connections for hard drives/accessories/deviceCons:Initial alarm that goes off until you turn it off manually (found solution on message boards)PoE connection not included (need a separate device)

I am obsessed with this NVR. I moved onto this after using BlueIris and I can't imagine going back. I was amazed by how effortlessly the NVR integrated with my six wireless cameras, auto-detecting them instantly and providing a truly plug-and-play experience. The packaging was excellent—complete with a mouse, SATA cables, and a sleek, quiet design that looks great on my desk. Its user-friendly interface, reliable motion alerts, and high-quality recording. I wish I had purchased one of these sooner.

I have 26 camera's connected works nice, can be a little slow sometimes going to different screens, but does what I bought it for
