If you have an antique analog camera, then where do you buy tubes for it today??

Once again, it is a Transmission, the camera is STILL DIGITAL.

 

 

Ironic is it not!

 

We use a digital ccd to give us video, and then we use a digital to analog converter, and then we put this signal on to a cable, and then it gets to a board where we hook it up to an analog to digital converter!!!!!!!

The core invention in the Digital Pixel System technology is the inclusion of an analog-to-digital converter (ADC) within each pixel of the image sensor. The ADC translates the light signal into a digital value at the immediate point of capture, thus minimizing signal degradation and cross-talk in the array and allowing for greater noise reduction methods. Once the data is captured in a digital format, a variety of digital signal processing techniques are used for optimal image reproduction.

The TW2804 includes four high quality NTSC/ PAL

video decoders, which convert analog composite to

digital component YCbCr for security application. The

TW280X contains four 10-bit A/D and proprietary

digital gain/clamp controllers and utilizes proprietary

techniques for separating lumin-ance & chrominance

to reduce both cross-luminance and crosschrominance

artifacts. The high performance dual

scalers in each channel offer two differently scaled

video outputs with 54MHz ITU-R BT.656 format for

security system design. Four built-in motion detectors

can also increase the feature of security system.

 

Both Rory, and AK357 are right!!!

dont forget about my 1000TVL Analogue BW CRT Monitor i've had for .. shoots 7 years now
