Ezviz HB90 test: a battery and two sensors to monitor the entrance and the garden without pulling cable

Ezviz has equipped its HB90 with two 4 MP sensors: one behind a large-angle optics for a field of vision of 110 ° diagonally. Furthermore, The other behind a more classic perspective for a diagonal 60 ° vision field. In addition, Going from the first to the second sensor allows you to benefit from an X2 magnification. Meanwhile, but also a monitoring of the movements on two axes, while it only works in the horizontal in the Grand Angle.

On the definition side, the two sensors are able to give birth to images of 2560 x 1440 pixels. However, The live flow can be viewed in HD 1080p. For example, 720p, and the manufacturer offers some brightness settings in addition to two modes for the night: in color with the spotlights or in black & white with the infrared LEDs.

Faced with the HB8 2K+. For example, which remains a reference among the outdoor surveillance cameras on battery with a 4 MP sensor there too, this model is well defended in the big angle. Similarly, His slightly less aggressive treatment even gives him a slight advantage. Nevertheless, The contours are actually less accentuated, as are contrasts. Certain very fine details, such as our colored points next to the book cover, are thus better preserved. Overall, the two cameras offer a good image quality, but the HB90 is positioned a (small) notch above.

When it is immersed in darkness, the HB90 camera soon reacts. The infrared vision as the spotlights start almost instantly. The rendering of our test scene is nevertheless a little disappointing with the first. all the more against the HB8 2K+. The image is darker. the contours much less clear, which can make the perception of certain very fine details, like the strands of hair in the portraits column.

The night vision in color offers a much better rendering of our scene. Additionally, The image is clearer and the brightness well controlled. The details are well preserved in dark areas as in ezviz hb90 test: battery two clear areas of the image.

The zoom of the HB90 is clearly not to its advantage in front of our test scene. The image is blurred and it is difficult to distinguish from important details. There are less supported contrasts. less blocked blacks, but the details do not stand out better, as the bitter is bad.

The infrared vision gives a very similar rendering, the colors less. Suffice to say that the zoom of the ezviz hb90 test: battery two HB90 does not make the weight in front of the HB8 2K+. its excellent infrared vision, if it may not be on the rocking speed from one mode to another. It is still almost instant.

If color night vision generally works well on our stage. it is content for the zoom of the HB90 to reveal the colors. The image is still so vague, if not anymore.

When it comes to identifying a face at the other end of our laboratory. the images of the HB90 are however of great help. Furthermore, The zoom even allowed us to identify a face up to 8 m with the infrared vision like that in color. The Grand Angle ezviz hb90 test: battery two does not allow you to see as far with the same level of details. but the owner can hope to identify an intruder up to 6 m, a good performance.
