I've recently bought two IP cameras:

TrendNet TV-IP100
D-Link DCS-900

They both sell for $80, and seem to be based on the same exact hardware --  
in fact, even some of the mechanical parts (stand, power supply, the lens 
piece) are identical. The firmware is also nearly identical (it was 
obviously made by the same people).

Both cameras work fine, except that DCS-900 tends to not work in my office 
and a couple of other spots -- the picture starts to have "waves" slowly 
moving up across it. Same thing happens to the IP100, except it has an 
"Anti-Flicker" checkbox, which the DCS-900 lacks.

I have a feeling that both units can run each other's firmware. I even had 
the crazy idea of downloading IP100 firmware, and trying it on the DCS-900 
(it has a better form factor). Alas (or "luckily for me"), there's no 
firmware on TrendNet's website -- even though there is a utility for 
updating it.

Does anyone know what the "flicker" is caused by? When I put my hand in 
front of the lens, the image gets brighter, and flicker disappears. It also 
works in another office just fine. The only difference is, my office has two 
types of light bulbs (different color temperatures), but the flicker happens 
in other places as well.

At one point, I was going to buy the DCS-950, but read too many complaints 
about the buggy firmware.
