AmcrestNV4108E-HS 4K 8CH POE NVR (1080p/3MP/4MP/5MP/6MP/8MP/4K) POE Network Video Recorder - Supports up to 8 x 8MP/4K IP Cameras, 8-Channel Power Over Ethernet Supports up to 6TB HDD (Not Included)

tl;dr - Company shipped an open-box return as a new item. Was missing HD mounting screws, and the previous owner had changed the admin password. At the time of this review, I have not been able to get the password reset.edit: Customer service is unable to reset the password and says to send it back. The company who makes the device (who claim to be affiliated with the seller) say that this is an amazon problem, that they ask that all returns be sent back to them but amazon does not comply. I'd take that with a grain of salt, myself, but that's their position. It's not their fault, there's nothing they can do about it.Longer version:So my company has been having some real problems with theft of tools and metal products. We've decided to install a surveillance system to try to see where the stuff is going. I bought this item as it appeared to meet my needs (IP cameras, POE, remote monitoring/alerts).When I opened it up, I noticed that the shiny plastic surfaces didn't have the removable protective plastic that you normally see even on cheap imported electronics. No big deal, I thought - some companies don't use it, and I don't care if it gets a little scratched anyhow.So I go to install the hard-drive. For budget reasons, I bought a 4TB WD Purple, this was lucky, as the manual says that it only accepts 4TB drives, despite the amazon page saying it takes 6TB drives. I can't comment on which is the truth. When I turned the device upside down, I noticed that there were shiny circles around the holes where the HD mounting screws bite into the metal. 'No problem', I assumed, they probably connect a HD during QC, maybe they screw it in for some reason?I open the unit and go to install my HD inside. 'Hunh, they didn't include a set of screws to install the drive. That's weird, the manual says four are included.'. Luckily, I have a box of such parts at home. Unluckily, I'm not at home. I make the 45 minute round trip and retrieve the screws.Hard-drive mounted, I plug the device into a monitor, connect the mouse and cameras and fire her up - ready to start configuring the cameras. Now, the manual says that the first thing that will happen is that a popup will appear asking me to change the password. This does not happen. 'No biggie,' I think to myself. Sometimes these manuals are written about obsolete firmware. I'll just find the option to set a new admin PW,And I can't log in. None of the default passwords work. I try variations on capitalization, try to connect to the default user account, nothing. It begins to dawn on me. This is a used device. Someone bought this, plugged it in, and changed the default password. They didn't like the device for some reason and returned it. The company, being both unethical and incompetent simply sent the device back out to another customer. They didn't bother to do a factory reset, they didn't bother to make sure the device worked, and they didn't bother to make sure that all the accessories that are meant to be included were included.I tried to navigate the password reset feature with the manufacturer, but their phone tech support person asked me to call back (long story) and when I did two minutes later the company had closed for the day. So now we have no security system for at least overnight, maybe for the whole weekend. That's the level of quality you can expect from this seller - I would suggest buying from anyone else.

Compre el articulo para poder grabar los videos de un par de camaras 4K tambien de Amcrest: IP8M-T2499EW y IP8M-2597EB-28MM. Sin embargo cual fue mi desagradable sorpresa de que puede grabar los videos 4K, sin emabrgo no puede reproducirlos. Describo mi experiencia con el producto a continuacion:- Puede grabar a 4K (como lo indica), pero a la hora de intentar reproducir los videos grabbados, resulta que no se pueden visualizar a traves de las aplicaciones ni del NVR, debido a que la capacidad de procesamiento no alcanza para ello. Hazme el favor!!!! Intenté hacer la reproduccion a traves de las multiples aplicaciones disponibles en diferentes computadoras, pero la aplicacion se cierra al reproducir solo uno de los videos almacenados en el NVR.Antes de tener el NVR, yo tenia la captura en la memoria de la camara y desde ahi podia reproducir los videos, con algo de latencia pero funcionaba, sin embargo, con el NVR ya no es posible. La unica manera de reproducir es bajando la calidad de los videos grabados y solo asi se pueden reproducir desde el NVR. Por si las dudas, estuve navegando en la pagina del fabricante donde mas de una persona se ha quejado por esta situacion y en algunos casos devolvieron el producto, en mi caso, aun sigo evaluando el conservarlo o definitivamente devolverlo, ya que simplemente no me es funcional de esta manera.- Es muy ruidoso. Tiene un pequeño ventilador que hace bastante ruido. Lo coloque en la sala donde tengo la TV principal y ahi conecte el NVR para poder monitorear las camara a traves de la TV, sin emabrgo el ruido que hace el ventilador es bastante alto, como para tener una estancia tranquila como solia ser, trate de coultarlo tras la TV y ahorar unos metros de cable, pero aun así, el ruido es bastante.- No venia con el CD de los programas, aun cuando la pagina de Amazon y la caja indican que si viene. Al parecer no es mucho problema por que puedes descargar varias aplicaciones de la pagina del fabricante, aunque tampoco es la idea andar buscando el software, cuando se dice que viene incluido.- Su interface no es nada amigable y es muy dificil de configurar si no eres una persona que le guste andar buscandole a estos menesteres electronicos. Resulta que el fabricante cuenta con varias aplicaciones que puedes emplear para la administracion del NVR y de las camaras. SIN EMBARGO, resulta que no todas las opciones de configuracion y visualizacion estan diponibles en todas las aplicaciones, es decir, en una aplicacion viene algunas opciones de configuracion que no vienen en otras, por lo que debes instalar varias (en mi caso son 3, desconozco si haya mas...) para poder administrar en su totalidad los equipos. Y si no eres una persona familiarizada tanto con la administracion de equipos de este tipo, seguro vas a tardar en poder administrar correctamente y sacarle jugo a lo que tienes.- No apta para trabajar de forma profesional. En mi caso lo compre para administrar dos camaras que permiten monitorear el frente de mi casa, sin embargo, se nota muuucho, que no tiene la capacidad suficiente para poder administrar mas equipos en 4K, si tu idea es administrar mas de 2 camaras 4k, buscale por otro lado. Con camaras de menor capacidad, no creo que tengas problema, el desempeño paraece no tan malo.- El PoE funciona bien, otra de las razones por las que encargue el equipo.En definitiva NO RECOMIENDO ESTE PRODUCTO dada sus limitadas capcidades.

I bought one of these, installed a 6 TB hard disk drive, added a couple of outdoor Amcrest cameras, and the whole setup was a nightmare. Impossible to set up without their tech support. The cameras lost contact with the system way too often. All in all, the entire setup was a complete and utter waste of money, and all of it other than that 6TB drive, is now in the trash.Once, when one of the cameras went offline, and I was 500 miles away from it, I called Amcrest tech support to get their help in getting it back on line. After giving me a few things to do in the app, the tech guy said "okay, now go and unplug the camera from the back of the NVR..." I was flabbergasted...told him I was 500 miles away from the camera...he had no way of getting it back online. Useless...out of date...old technology...don't waste a penny of your money on this company's equipment.

I rarely write negative reviews but this time, other customer have to know how bad is the amcrest customer service!During a night, i murder happen in front of my shop. Then, in the morning, a police officer asked me to extract the video from my camera to help him resolve the case. I tried to extract video but i was not able to do that, so i contacted amcrest tech support...It took 8 days, many email and 3 phone call before i get help from amcrest, but it was too late: with my hard drive, this recorder just record 4 days back!! So 8 days after the event, the video that the police wanted was already erased! This is very frustrating because now the police officer think that i refuse to give him the video, and he think that i have something to do with the murder in front of my shop because i refused to give him the video!!!Amcrest tech support is VERY SLOW, VERY BAD, and the put me in a VERY BAD SITUATION!!!!I'm not the only one who complain about this inexisting tech support, trust me, if you dont need teck support this item is not too bad, the only issue i have with this NVR is when i plug 4k camera (from amcrest too) it lag... Other 4mp camera run smooth, but the picture using the 4K cams is laggy/jumpy on my monitorIt is complicated to understand all the function at first, but for the price i paid nvr is not to bad (as long as you dont need help from tech support)

Pude conectar cámaras de 4mp de otras dos marcas. Las reconoció fácilmente gracias al protocolo ONVIF.Trae un procesador rápido , comparado con el de otras dos marcas que use.No deja usar la comprensión en formato H.265 desde el NVR, creo que depende de la cámara. No la he probado con una cámara 4k.Hace ruido , pero no es molesto.Tengo unas dudas en cuanto a la cantidad de energía que envía. Ya que en una ocasión envió “ruido” a las cámaras.No he logrado configurar las cámaras vía http desde la pc al NVR. Puedes configurarlas desde el NVR , pero solo cosas sencillas.Dentro del nvr hay un led de color rojo que está constantemente encendido.
