Amcrest introduces new 4k outdoor poe camera – the Amcrest ip8m-mb2546 4k varifocal camera with 4x optical zoom. How this Amcrest ip8m-mb2546 product is compared with Lorex lnb9272 varifocal lens and Dahua?

Amcrest Ip8m-Mb2546

This Ip8m-Mb2546 is Amcrest’s first product in the 4k resolution with a varifocal lens and bullet model camera category, whereas the previous product Amcrest ip8m-2496 is the first Amcrest product in 4k resolution but with a fixed lens. Although previously Amcrest has also released dome model with a varifocal lens (Amcrest ip8m-2454e) and Amcrest ip8m-mt2544e with Turret model which are also with a varifocal lens and 4k resolution, but ip8m-mb2546 is the first bullet model with varifocal lens @ 4k resolution.

Starvis sensor

One of the advantages of this product is the Sony Starvis CMOS sensor which has a bright image quality in low light using backlight illumination technology rather than front light illumination technology that allows the wide range of light to be collected at CMOS to achieve high sensitivity. It’s similar like a starlight CMOS technology which is also using backlight illumination technology. Besides that, Amcrest ip8m-mb2546 can also view and record colors up to low light with a minimum value of 0.05Lux and will switch to using Infrared up to 164ft range in black and white night vision when it is totally dark.

4k @15 fps

Amcrest Ip8m-Mb2546 uses a Sony CMOS sensor with a maximum resolution of up to 4k @ 15 fps, but if you expect a smoother frame rate @ 30 fps real time frame rate this camera can only be up to 2k resolution.

We will compare the first Amcrest bullet model security camera with varifocal lens @ 4k resolution with two competing products from Lorex and Dahua. Lorex has many variants, both bullet models and dome and turret 4k security cameras. Lorex Lnb9272 is one of the Nocturnal security camera series that is specifically designed to work great at low light and color night vision.

In brief, Amcrest ip8m-mb2546 can be summarized as follows.

Lens

With fixed lens camera, the image quality is sharp, but you only have one fixed view angle you need to adjust manually to fit the suitable view angle. Unlike the fixed lens, varifocal lens allows you to adjust the viewing angle of the camera on the fly with your mobile device and the app. With varifocal lens you can zoom in to see the license plate more clearly, as well as the face you can zoom much clearer than the zoom by software or digital zoom.

Dahua offers more optical zoom and wider view angle compared with the other two products.

Night vision

Among these three products Lorex excels in the range of IR LEDs up to 400 ft. And with ambient light you can enjoy color night vision with its Color Night Vision (CNV) technology. Compare with Amcrest and Dahua which can only be up to half of Lorex IR range. And indeed the Lorex lnb9272 is one of the Lorex Nocturnal series cameras specifically designed for maximum performance in low light condition.

Storage

If you frequently monitor your property when you are on the go, it is better to subscribe to cloud storage plan to make it easier to access video footage with your mobile device. Although this Amcrest camera has memory slot for local storage with micro SD Card up to 256GB, but it will be easier and faster access from cloud storage compared to access footage from your local storage or NVR system via your home internet connection.
