I have a Small business and want to upgrade to an HD camera system?
If you are confused between AHD, CVI and TVI, then the correct choice will be TVI, because it has better quality then the AHD and CVI.
Currently, I have a security camera system that is about five years old, and I don’t know how to find out what kind is it?
You look for the model# under the DVR and Google it. Second option if it has BNC connectors and is over two years old, chances are it is Analog. You can upgrade to HD-TVI cameras and DVR. Recommended cameras 2MP 1080P.
