Can i use the Canon IXUS 700 as a webcam for my desktop PC ?

The IXUS 700 works with SD and MMC cards, 2GB and smaller. It will not work with higher-capacity SDHC cards.

What are you confused about? This is the correct replacement battery.

Pros don't use camera via USB cord to download...they use separate card readers. Why don't you?

Sorry, but according to Canon's technical specs, your camera was designed only for use with standard SD card format. SDHC format will not work with it, and will likely give you a memory card error.

The ixus 700 is only specified to be compatible with SD memory cards (and MMC cards). The protocol for SD cards only covers up to 2MB. Cards of higher capacity are the SDHC (high capacity) protocol, but this protocol did not exist when the ixus 700 was introduced. As far as I can tell, there is no way to upgrade to be compatible with the newer protocol.

The IXUS 700 works with SD cards, 2GB and smaller. It will not work with higher-capacity SDHC cards. You need to use SD cards, 2GB and smaller.

The IXUS 700 is called the SD500 in some parts of the world. You may download the SD500 manual and more from here.

I understand that it takes a maximum of 2GB. Still loads of photo/video capability. Don't make the mistake I did of buying a 4GB SDHC card for it. It won't take it.

I would think that as long is it is a sd memory card then it would be compatible since the camera uses the sd card and the 4gb is for photo storrage
