1. High Pixel

Pixels are a unit used to calculate digital images, just like photos of Webcam. Digital images also have continuous tone levels. If we enlarge the image several times, we will find that these continuous tones are actually composed of many small square dots with similar colors, which are the smallest unit pixels that make up the image. The smallest graphic unit that can be displayed on the screen is usually a single colored dot. The higher the pixel position, the richer the color palette it has, and the more it can express the realism of colors. A pixel is usually considered as the smallest complete sample of an image.

2. Low illumination

Illumination, also known as sensitivity. It is the sensitivity of CCD to ambient light, or in other words, the darkest light required for normal CCD imaging. The unit of illumination is lux. The smaller the LUX value, the less light is needed and the more sensitive the camera is.

3. Wide dynamic range

Z25 Network Camera not only obtain bright images in dark places, but also ensure that bright areas are not affected by color saturation. With the support of wide dynamic technology, the camera can capture more than applications anywhere. It can combine images generated by using high-speed shutter exposure in high light conditions and low-speed shutter exposure in low light conditions to generate composite images, thus obtaining details in dark areas without being too saturated in bright areas of the image.

4、3D-DNR

IP Camera use powerful processing capabilities of dedicated DSPs to effectively process image information through detection and analysis of frame memory, greatly eliminating interference and noise waves in the signal, thereby effectively improving the clarity of the image.
