HD Analog Four Way Cameras Tested

By Ethan Ace, Published Aug 28, 2015, 12:00am EDT

One camera that delivers AHD, HDCVI, HDTVI and 960H, all for as little as $15 a camera.

Both on price and claimed support, that is pretty outstanding. And we are hearing from people all over the world who are considering these cameras.

How well does the 'four way' work? Can you really just adjust a control (see right) and get high-quality AHD, HDTVI and HDCVI?

Comparison shots of the three Analog variants, sensor on left (topside) with processing chip on its right (bottomside).

Athough I don't disagree with IPVM's "don't buy' recomendation, I think its worth stating that for $15 this is quite a feat of engineering.

Furthermore the fact that it was (apparently) done against the wishes and assistance of all three of the IP holders, suggests that a viable and competitive universal chipset is not far off. And if the three IP holders wanted to help, we'd have it even quicker.

After all, this is gen 1 combo chip. Remember some of the early CVI,TVI, and AHD product. If the 960H worked well, that alone is worth $15.

Moreover, I would ask IPVM to re-evaluate their assessment of the CVI panel. I'm not sure that the genuine CVI image is clearly better. Look at the eye-chart for instance:

Just because it is a feat of engineering does not mean one should buy it.

If these companies come to an agreement, if they 'hackers' can improve the hack, it's worth reconsidering.

If the hackers can improve their hack, and started to sell significant product*, that would be a damn good reason for the three to come to an agreement, no?

Negotiated by ours truly, of course.

*without the others being able to shut them down legally.
