What is the best system to buy for away from home vacation survaliance

[cheris]

Very confussed looking at all the options.
Need something simple..lol.. I can read and follow directions well, but nothing too complicated when it comes to high tech stuff..

Can someone tell us what the best system would be to view a few 2- 3 places outside our home while we are gone on vacation, would like to view what it sees online. Anything priced around 100- 200 dollars ..?? Will there need to be an on going internet connection for it to use ? If we use a battery pack that is mentioned in some of the descriptions how long does it last ?

ALSO a 2nd system to view just 1 place at our our vaction home ? Maybe priced about 100 .. Would also like to view online.

Thanks in advance.
