Amcrest UltraHD 4K (8MP) Outdoor Security IP Turret PoE Camera, 3840×2160, 98ft NightVision, 2.8mm Lens, IP67 Weatherproof, MicroSD Recording (256GB), White

4K is worth the upgrade!
I purchased this PoE camera as a direct replacement for an older Amcrest PoE camera, which has given me a couple years of perfect performance. The camera being replaced is an IP2M-851EW, which includes a similar fixed dome lens setup with 1080p @ 30fps, 128 degree viewing angle, IP67 with 98ft. night vision. I want to highlight the definite performance advances with this newer camera.InstallationI have installed several different types of bullet and dome cameras, and this one is just as easy and solid as any other out there. Amcrest provides a template for screw placement (I did not need it) and any adjustments past needing a screwdriver can be made with the included tool. The camera was well boxed and padded.The first thing I noticed was a white balance difference, between the two cameras. It is apparent that the lens is calibrated to a more natural tone. Saturation also appears to be more accurate as well. For activity at a distance it will be much easier on this 4K camera to pick out identifying details, in comparison to the previous 1080p feed.Zooming in with the AmcrestViewPro app (no optical lens zoom) the 4K quality really shines at a distance. If my neighbors across the street had a theft occur with entry to their front door or vehicle, I would now have a decent chance of catching some identifying features, as opposed to the previous 1080p camera.Night Picture QualityThere is a noticeable improvement in low light capability, allowing me to now see some clear low light definition at the end of my driveway, where the old IP2M did not reach. The IP2M advertised 98ft. night vision capability, while this IP8M boasts up to 164ft! What really improves the low light capability is removing near-field reflections of the IR LED’s (hanging plant) and toying with image adjustments such as brightness and contrast. Distance clarity shows a marked improvement!Picture AdjustmentsAttempting to improve the night vision capability using picture adjustments had mixed results. Object definition at a distance improved slightly with increased brightness and contrast, but at the cost of a grainier image. I believe that factory calibration on this camera is optimal and maximizing night vision will be dependent on removing near-field object reflections and adding ambient lighting at a distance. Exceedingly bright lights within view can cause the rest of the field to dim as the camera adjusts for the lighting. The claim of 164ft. night vision capability is probably accurate but requires the correct setup.Viewing AngleI was hesitant to purchase a camera with a smaller viewing angle (112° in the IP8M vs 128° in the IP2M!) since I need wide coverage, but I would be hard pressed not to believe that the IP8M isn’t actually wider in my application.OverallOverall, this Amcrest 4K POE camera fit the bill. It was exceedingly easy to set up with the included QR code and a smart phone, using the AmcrestViewPro app on an Iphone. I can only assume it is just as easy on Android, as I have been using this App for some time and it has developed well. There was a modest improvement in night vision capability over the older generation 1080p camera, but it really shines in picture resolution and color accuracy. The app is relatively intuitive to use, including motion detection which allows you to be very specific in what spots of the picture trigger an alarm, which can be set for push notifications and even email, including photos and video clips. I have not yet used the cloud recording service, but unless you have an NVR, that will do just fine at a subscription price. I would recommend this camera and definitely the Amcrest brand over many others, they are rock solid in the home surveillance arena.

Works great

Tengo un mes con ella y la verdad es un excelente equipo.De entrada, la estructura de la camara es toda de metal. Lo que le hace mas resistente y ayuda bastante bien a disipar el calor que produce todo el procesamiento de imagenes en 4K. Fue facil de montar en mi caso particular, para su orientacion, puedes simplemente girar la esfera y direccionar el area que deseas abarcar. El ángulo de vision es bastante amplio. TIENE MICROFNO INCLUIDO, con lo que puedes grabar el audio, lo que la hace mas versatil. Puedes instalar una memoria micro sd de hasta 128, lo que es suficiente para grabar en 4K sim mayor problema. La administracion y configuracion de la camara es su parte debil, ya que no es del todo intuitiva, para una persona primeriza que le encanta la tecnologia como yo, me resulto algo dificil poder configurar todas las opciones necesarias, pero despues de configurada, va de maravilla.En mi caso, la calle siempre esta iluminada de dia y de noche, asi que no requiero de la lusz infraroja, pero en el par de ocasiones que la probe, me resulto con bastante alcance, aunque no estoy seguro del alcance total ni de los detalles nocturnos que puede capturar.La recomiendo totalmente.

Excelente calidad de imagen, fácil instalación y la app es aceptable. Funciona con blue iris y con synology surveillance station.No funciona con alexa en México
