HDCVI : PHDCVI cameras are the latest high definition cameras in the CCTV industry that support resolutions up to 2 Megapixels.
The most important reason you should consider HDCVI cameras as part of your system is that they work over existing RG59 coax cable.
If you already have good quality coax cable, i.e the kind that you get in a spool or roll of cable, then you can save yourself a lot headache and expense when upgrading your CCTV camera system to high definition instead of going with IP.
We prefer HDCVI over HS-SDI, the other type of camera technology that allows for megapixel video over coax.HDTVI : HD-TVI cameras are a type of analog high definition CCTV security camera (megapixel video over coaxial cabling / HD over coax) that supports up to 1080p video resolution.
HD-TVI cameras are a great alternative to traditional analog CCTV and megapixel IP surveillance cameras because of their superior video quality and ability to use RG59 coax cable.
TVI cameras are used by professional and DIY installers because they are so affordable and simple to install.HDTVI: A digital camera that accepts different lenses but does not use a mirror to reflect the image into the viewfinder.
