PTZ Wifi IP Camera Outdoor Night Vision

Surveillance camera is a semiconductor imaging device, which has the advantages of high sensitivity, strong light resistance, small distortion, small size, long life, and anti-vibration. Surveillance cameras in security systems.
The generation of the image is mainly from the CCD camera at present, and the stored charge can also be taken out to change the voltage. It has the characteristics of anti-vibration and impact and is widely used.
On December 1, 2017, the "Specifications for English Translation and Writing in the Public Service Field" was officially implemented, which stipulated that the English name of the surveillance camera standard is: Surveillance Camera. By imaging color
(1) Color camera: It is suitable for identifying the details of the scene, such as identifying the color of clothes or scenes. Because of the color, the amount of information increases, and the amount of information is generally considered to be 10 times that of a black and white camera.
(2) Black and white camera: It is suitable for areas with insufficient light and areas where lighting equipment cannot be installed at night. When only monitoring the position or movement of the scene, a black and white camera with a resolution usually higher than that of a color camera can be selected.
By camera resolution
(1) Low-grade type with image pixels of about 250,000 pixels, color resolution of 330 lines, and black and white resolution of about 400 lines.
(2) Mid-range type with image pixels between 250,000 and 380,000, color resolution of 420 lines, and black and white resolution of 500 lines and below
(3) The image should be more than 380,000 dots, the color resolution is greater than or equal to 480 lines, the black and white resolution, and the high resolution of 600 lines or more.
By camera sensitivity
(1) Ordinary type: The illumination required for normal work is 1~3 (lux)
(2) Moonlight type: The illumination required for normal work is about 0.1 LUX
(3) Starlight type: the illumination required for normal operation is below 0.01 LUX
(4) Infrared illumination type: In principle, it can be zero illuminance, using infrared light source for imaging.
According to the size of the CCD target surface of the imaging element
(1) The size of the 1in target surface is 12.7mm wide X 9.6mm high and 16mm diagonal
(2) The size of the 2/3in target surface is 8.8mm wide X 6.6mm high and 11mm diagonal
(3) The size of the 1/2in target surface is 6.4mm wide X 4.8mm high and 8mm diagonal
(4) The size of the 1/3in target surface is 4.8mm wide X 3.6mm high and 6mm diagonal
(5) The size of the 1/4in target surface is 3.2mm wide X 2.4mm high and 4mm diagonal
