Question: what is the difference between hd tvi and hd sdi?
Answer: It is backwards compatible with analog cameras and is available in 720P or 1080P versions. ... HD-TVI is backwards compatible, unlike HD-SDI, so you will still be able to connect traditional analog cameras. If you are considering HD-SDI or HD-CVI, we think the best bet is to look at IP cameras or wait for TVI.
