SECURITY CAMERAS FEATURES - IMAGE SENSOR
CMOS IMAGE SENSOR & CCD IMAGE SENSOR
Every surveillance camera system needs an image sensor to create a video. An image sensor is the part of a security camera that captures the light hitting the camera lens and converts it into electrical signals. It is a chip made up of millions of light-sensitive components (photodiodes or phototransistors) that capture the projected waves of a lens, which makes up the image. Image sensors can use in devices, such as digital/security cameras, medical and vision equipment. Image sensors range in size, but the most common are 1/2.8″ and 1/3″. The image sensor dimension impacts the security camera’s field of view for a given lens and light sensitivity.
When a video camera is manufacturing, two leading technologies can be used for the image sensor: CCD (Charged Coupled Device) and CMOS (Complementary Metal-Oxide Sensor). CCD and CMOS image sensors are two different technologies for capturing images digitally. Both types of imagers convert light into electric charge and process it into electronic signals. While CCD and CMOS sensors are often seeing as rivals, each has unique strengths and weaknesses that make it appropriate for different security camera applications.
CCD IMAGE SENSOR - SECURITY CAMERAS
CCD stands for Charge-Coupled Device and is one of the oldest image-capture technologies used on surveillance cameras. CCD image sensors have been around for over 30 years and are often found in older cameras. The image quality in a CCD image sensor is good because it produces less noise and better sensitivity than in a CMOS image sensor. However, the only disadvantage is its heavy circuitry required outside the sensors for conversion and amplification and needs heavy power consumption. CCD sensors are more expensive and more complex to incorporate into a security camera Miami. The increased power consumption may sometimes result in issues like excessive heat generation within the CCTV camera. A CCD sensor can consume up to 100 times more energy than an equivalent CMOS sensor. CCD sensors are also more expensive and more complex to incorporate into a security camera.
CMOS IMAGE SENSOR - SECURITY CAMERAS
CMOS stands for Complementary Metal-Oxide Semiconductor, also known as active-pixel sensors. Instead of using analog methods to turn light into data, CMOS image sensors use transistors situated at each pixel to capture and transform light. That is a much more flexible way to take digital images as each pixel has its transistor path. Additionally, with a CMOS image sensor created in the same way that microchips are, they’re easier to produce using traditional manufacturing methods. That makes CMOS image sensors cheaper to make – and is why IP security cameras are much more affordable now than they were in the past. Most security camera systems use a CMOS image sensor because CMOS image sensors perform better than CCDs, offering faster speeds with lower power consumption. Since CMOS image sensor doesn’t require a separate image processor as CCD sensors do, they need a lot less power. Compared with CCDs, a CMOS image sensor has a faster readout (which is advantageous when high-resolution images are required). Higher immunity to image noise, lower power dissipation at the chip level, and a smaller system size enable more integration possibilities and more functions.
SECURITY CAMERA IMAGE SENSOR - APPLICATIONS
Image sensors are used primarily in security cameras and in many imaging devices used in industrial, media, medical and consumer applications. CMOS image sensors & and CCD image sensors are widely used in camera modules, camcorders, smartphones, PC cameras, personal digital assistants (PDAs), machine vision, and videoconferencing. Image sensors are also widely used among toys, games, optical mice, document scanning, barcode readers, and scientific imaging.You can contact us for a consult on the better security camera installation according to your necessities.
