As its name indicates, the BC1C 2K+ is equipped with a 4 MP sensor which allows it to shoot up to 2K. However, the resolution can be lowered to 1920 x 1080 pixels or 1280 x 720 pixels. Ezviz delivers with this an optic that covers an angle of 116 degrees (diagonally), two infrared LEDs for the night, but two projectors at night as well – the night vision is in black and white with the first and changes to color with the seconds. Finally, note that Ezviz offers another high and low level color saturation adjustment.
Per day
As is often the case with Ezviz, image quality is satisfactory under lighting that simulates daylight. The level of detail is sufficient to distinguish between facial features and textures that are not fully polished, as can be seen on other models, such as Google Nest Cam (Battery).
However, we don’t see any real gain compared to our test scene capture that was performed under the same conditions with BC1, which remains our standard for external battery-powered cameras, despite the 2-megapixel sensor. The image lacks sharpness in the periphery, and the new 4MP sensor used by Ezviz manages brightness less, causing a loss of detail in the bright areas of our test scene. Outside, the walls of the buildings surrounding the courtyard were partially burnt out. HDR mode will be welcome.
night
BC1C 2K+ blows hot and cold after dark. Infrared vision is somewhat disappointing. The sharpness issue mentioned in our daylight shot is exacerbated and extends to the center of the image. Thus, reading some details of our scene becomes more difficult, especially on the faces. Here again, the BC1, despite its only 2-megapixel sensor, delivers better photos. On the other hand, in both cases we notice a stronger illumination in the center than in the extremities, but also a rather convincing management of dark and light areas.
And, on the contrary, the color night vision obtained using projectors brings very good results. The image is sharp and rich in detail, even a little more daylight in bright areas. If the camera avoids overexposure issues, blacks can appear obscured on the other hand, especially in surroundings where projectors are lit less.
Even with this small flaw, it’s much better to activate the color night vision of the BC1C 2K+ night watch camera, our recognition test confirms. We were able to identify a person at a distance of about 4 meters by relying on images taken with projectors, as opposed to 3 meters with infrared vision. The motion detection range does not change regardless of the mode used. We measured it at about 8 metres…for lateral movements. On the other hand, we could have gotten as close as 4m from the camera without being spotted by walking directly onto it, even by waving our arms in all directions.
Finally, it should be noted that the first seconds of the triggered event will not be logged. Since the video does not run continuously to save battery power, it is only activated when the PIR sensor detects motion. The camera must then activate the night vision in turn, so 2 to 3 seconds can be lost.
