17. Conclusion
AHD/CVI/TVI they claim they are 3C2V 300Meters, But in fact, Image detail loss happened in 100M.
In same condition, AHD/CVI/TVI the real distance should be < 70Meter, ccHDtv is 3C2V >420M.
Even DTV transmit 1080p60/1080p30 image, The above data will not be changed. Because the channel capacity is 10Mbps.( 720P only use 3Mbps)
AHD/CVI , transmission by analog baseband. So they are sensitive for cable quality. If the cable ibecome aged or , the image quality low down. Also AHD /CVI take more band width than tradition al CCTV so they are not suitable for upgrading market from SD to HD.
We use standard 3C2V cable for this testing. Usually Installer use cheaper 3C/5C cable so the image of AHD/CVI/TVI will be worse.
Even for distance shorter than 100 meters, because of Sun/Rain etc reason causing the poor quality of cable. Sever months/years later, the image of AHD/CVI/TVI will equal to about 300 meters.
