There are alot of different types of cameras that will work for you and some of the security kits at Staples might be the best option. I've been voluntold to help out at a friend of my wifes restaurant many times on the computer and cameras and learned a few things BUT someone that deals with them regularly will know much more. But from what I have learned there are a couple of things to make note of that should help.
1) If you have a dynamic IP on your internet used you may have to use a service to log in OR you will need to know the IP and hope it doesn't refresh when you are out/away.
2) If you are using several devices to view using something like SIMPLEDDNS ( I THINK that is what they are using) as a gateway, it lets you set it once on each device (pointing to the Simpleddns) and if the IP changes you only log into the simpleddns webpage and change it. It is free BUT a pain in the butt since you have to be able to get onto the local computer where the camera is to find the IP and then change it on the webpage.
3) Make sure you have a password setup, the viewers should let you put one in so you don't have to use it each time. I was looking for a camera to view something months ago and stumbled across this site.

You can see the make of the camera and some have night vision (important for security), some make sense like scenery etc. and some are beyond just creepy ones that someone setup a camera at home and didn't set a password. My favourites are:
This one is a camera in Texas that has night vision and you can check out some BIG deer

Downtown Brampton

BUT if you don't setup a password you may end up on here ...

4) As mentioned above, night vision, usually infrared LEDs used for that, you can look at some of the cameras above in Australia or Japan to see those that do and do not have night vision.
There are also cameras that you can get that take a picture and can email it to you. I bought a basic one for home when we go to the cottage and just turn it on when we leave and it takes pictures and emails them. Sometimes I end up with 20+ in a day, the neighbour has a dog, news papers etc. It doesn't let you check but doesn't require anything more than being able to get the email. You also have an image in the email as compared to a screen shot or capture of the video.
Now the information I have is probably a couple years old now so if you can find a shop that sets them up that will answer questions it may be worth paying the extra or if you are technically capable and have time you can get your own setup but you have to think about how much to spend, what and how it will be used and where to put the cameras. Before you put any money down on a specific model try googling it to see of there are examples or complaints since it would be a pain to take down and return if it sucks.

P.S. Remember the password unless you have a specific reason no to.

This one needs cleaning but has a dome with a wide angle fish eye view ... that would be good for some locations but you would have to look later to see the night vision (if any) ....looking at the model it might just be a door bell camera... oh and if you know them tell them they need to rake the leaves.
