Electronic Alarms and Home Security Devices - Trendware ethernet camera?

I have a store I would like to put 3 maybe 4 ethernet cameras in.

I want to be able to monitor the store from my home when I am not there.
These are supposed to have built in FTP services so upload to a webserver would be possible

I feel the cameras will keep most everyone honest.

How large of a hard drive will I need to store the images?

I want to be able to monitor all 3 or 4 cameras at the same time. Anyone have any other ideas besides trendware?
The wired cameras are available for $105 and the wireless ones are $150-195

Thanks for any advice

The size of hard drive required will depend entirely on how much you compress the captured images and how long you wish to store them. I would think that an 80-120GB drive dedicated to storing the images should be more than enough, and you could probably get by on far less (~40GB).

I would also suggest looking at the D-Link DCS-2000 (http://www.dlink.com/products/?pid=142). They're a little more expensive, but I have used them and had good results. The D-Link's do also come with software that allows you to have video feeds from all 4 cameras tiled on one screen.

Look into the Panasonic Netcams also. Like the D-Links they are a little more pricey than the Trendware, but as a certified Netcam installer, I can say they are good equipment with all the features you are looking for.

FTP may not be an ideal solution for what you are wanting to do. Essentially, FTP is just going to give you a bunch of uploaded pics, you're not going to have recorded video to review.

You may be better off using a remote DVR type setup - where the images are recorded to the computer locally, and you can access that computer remotely through the internet. This setup would also allow you to use analog cameras at the remote location - much cheaper than IP-addressable cams.

Good luck!
