4 pack of Outdoor Color CMOS 400TVL Cameras with 6mm and 3.6mm lenses and 30ft Night Vision

CCD sensors, create high-quality, low-noise images. CMOS sensors, traditionally are more susceptible to noise. 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. Many of the photons hitting the chip hit the transistors instead of the photodiode. CMOS traditionally consumes little power. Implementing a sensor in CMOS yields a low-power sensor. CCDs use a process that consumes a lot of power. CCDs consume as much as 100 times more power than an equivalent CMOS sensor. CMOS chips can be fabricated on just about any standard silicon production line, so they tend to be extremely inexpensive compared to CCD sensors. 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.

This camera has a BNC female connector for video and a female 12 volt, 2.1mm power connector.

This camera can be run from as far as 200 ft. when using 60 ft or 120 ft extension cables. With one single RG59 cable, this camera can extend up to 800 ft. You can go to up 1800 ft using RG6 cable.

A fixed focal length lens cannot zoom. The focus is fixed. A fixed focal length lens usually allows more light to pass through the lens at a given focal length than a varifocal, or zoom lens. This can be important in low light situations.

The cameras themselves do not detect motion. In order to record motion you need a motion detection DVR. When power is supplied the cameras will continually send video feed through an RCA cable (wired) or through the air (wireless).

Resolution refers to the number of lines in the cameras video image. The higher the resolution, the better. Lux refers to the amount of light that is needed for the camera to see. This becomes important if you need the cameras to see in low light. The lower the Lux, the better.

Cameras have a working temperature range in between 14F to 130F. If the temperature falls below the minimum for a long period of time, it could damage the camera. The best solution for this is putting the camera in a heated enclosure.

The cameras that come with this bundle are low cost cameras that have good color indoors and clear images indoors and outdoors, but the sensors used in these cameras can produce off colors when in shadows or are exposed to bright sunlight in many situations. That is the nature of the sensor and we can not change that. If you would like to exchange the cameras that came with the bundle with higher quality cameras with better quality color we do have a special offer for customers who purchased this bundle. You can exchange the cameras for ones with Sony CCD color sensors for just $100 for all 4 four cameras. If you would like to take advantage of this offer then contact the customer service dept at cs@dpsi-usa.com, or 877-998-3440 x 538 and they can arrange this for you.

On this camera there are 5 primary LEDs on the inner ring that come on bright and provide most of the lighting. The other LEDs provide fill in light and come on as needed so they are not as bright.

You can use CAT5 cable, you would need to use video baluns to attach the cable to the camera and the DVR. If you use powered video baluns you can also send power to the cameras through the CAT5 cable.
