Smar Security Cctv 720p 1080p Ahd Camera Outdoor Waterproof

Surveillance cameras are semiconductor imaging devices that have advantages such as high sensitivity, resistance to strong light, small distortion, small size, long lifespan, and resistance to vibration. In the security and prevention system of surveillance cameras.
The current generation of images mainly comes from CCD cameras, and the stored charges can also be extracted to change the voltage, which has the characteristics of anti vibration and impact and is widely used.
On December 1, 2017, the English Translation Standards for Public Services were officially implemented, which stipulated that the standard English name for surveillance cameras is Surveillance Camera.
Divided by imaging color
(1) Color camera: suitable for distinguishing details of scenery, such as identifying the color of clothing or scenery. Due to the presence of color, the amount of information increases, which is generally considered to be 10 times that of a black and white camera.
(2) Black and white camera: suitable for areas with insufficient lighting and areas where lighting equipment cannot be installed at night. When only monitoring the position or movement of scenery, black and white cameras with resolutions usually higher than color cameras can be selected.
Divided by camera resolution
(1) A low-end model with an image pixel of around 250000 pixels, a color resolution of 330 lines, and a black and white resolution of around 400 lines.
(2) A mid-range model with image pixels ranging from 250000 to 380000, color resolution of 420 lines, and black and white resolution of 500 lines or below
(3) Images with a resolution of over 380000 pixels, color resolution greater than or equal to 480 lines, black and white resolution, and high resolution of over 600 lines.
Divided by camera sensitivity
(1) Normal type: The required illumination for normal operation is 1-3 (lux)
(2) Moonlight type: The required illumination for normal operation is about 0.1 LUX
(3) Starlight type: Normal operation requires illumination below 0.01 LUX
(4) Infrared lighting type: In principle, it can be zero illuminance and infrared light source imaging is used.
