IP Mapping

D-Link Internet Cameras feature either:

• CCD (charge-coupled device) Sensors

or

• CMOS (complimentary metal-oxide semiconductor) Sensors

How are they different?

CMOS Sensors

• CMOS sensors are more susceptible to noise which creates interference and distortion in the image.
• Because each pixel on a CMOS sensor has several transistors located next to it, the light sensitivity of a CMOS chip tends to be lower.
• CMOS traditionally consumes little power. Using a CMOS based camera requires less power on a network and is more power efficient.
• CMOS chips can be manufactured in mass quantity, so they tend to be extremely inexpensive compared to CCD sensors.
• CMOS sensors have lower quality, lower resolution and lower sensitivity. CMOS sensors are just now improving to the point where they reach near parity with CCD devices in some applications.

CCD Sensors

• CCD sensors are less susceptible to noise which creates high quality images with very little interference.
• Light sensitivity of a CCD sensor tends to be high.
• CCD sensors consume lots of power, as much as100 times more power than an equivalent CMOS sensor.
• CCD sensors have been mass produced for a longer period of time, so they are more mature. They tend to have higher quality and more pixels.
• CCD sensors tend to be used in cameras that focus on high-quality images and excellent light sensitivity.
