Answer
The simplest process is to buy a network IP camera. This is the camera you can connect to your PC network card using RJ45 plug or to your network switch or router.
You can buy any cheap model from AXIS(my first camera was AXIS, I like them very much), Arecont Vision, Panasonic, Sony, Trendnet (cheapest of the list).
Network IP cameras are modern. The only disadvantage - they are more expensive in compare with traditional analogue CCTV cameras.
If you purchased analogue CCTV camera, you can connect it to your PC using 2 ways:
- buy DVR card (old way, i would not go this way)
- buy an ip video server or video encoder l(like AXIS M7001, quite good for its price, see here: http://www.axis.com/products/cam_m7001/ or AXIS 240Q if you need to connect 4 cameras).
To choose a camera with proper lens (lens with different focal length have different angle of view), camera locations as well to choose your compression for HDD you have you can use IP Video System Design Tool from http://www.jvsg.com or special online calculators.
If you need high resolution camera (like 1-4 Megapixel) go for network camera. Also if you need to watch high speed objects, choose a camera with progressive scan.
If you build a network CCTV system you need to run some software on your PC. The list (a little bit outdated) of not too expensive software is on http://www.video-home-surveillance.com . Also you can have a look on forums networkcamerareviews.com or cctvforum.com to see what other people use.

Which Camera is good for Landscape photography?
whatapwrtr
I have never had anything better than a 100$ digi cam to take photos with. But photography has always been a dream of mine. I want a camera in the 300 - 1000$ range that would be good to take pictures of...well everything but mainly landscape.
The problem is that I dont know which type of model to get. Should I get a dSLR? How good are superzoom cameras? Please help! Now that I finally have money for a cam, i cant wait to get one.
Answer
For the best images a DSLR should be what you're looking for. You want a large sensor for better detail and color. However, the lens used really matters since landscapes are usually done with a wide-angle lens. Another item I consider mandatory for landscape photography is a good solid tripod.
With a basic DSLR like the Sony A580 or Pentax K-r or Canon T3 or Nikon D3100 you'll get an 18-55mm zoom lens. Although 18mm isn't as wide as some people might like its still suitable for making good landscape pictures. The trick is in knowing how.
One of the first things you need to learn about is Depth of Field (DOF). Landscapes require a deep DOF so that everything from the foreground to infinity is in focus, especially since its always a good idea to have something of interest in the foreground. There are only three factors that affect your DOF:
1) The focal length of the lens.
2) The f-stop used.
3) The subject distance.
These sites will help you learn about DOF and how to control it:

3) http://www.illustratedphotography.com/photography-tips/basic
At Site 1 you can use the DOF Calculator to compute your DOF using any combination of the three factors imaginable. With a Sony, Pentax or Nikon DSLR and using the 18mm end of your zoom you can achieve a very deep DOF. Here's how:
Set the aperture to f16 and focus on a subject at 5 feet away. Lock the focus.Your DOF will be from 2'-0'' to infinity so anything 2'-0'' in front of your camera to as far as you can see - infinity - will be in focus. Now find a worthy scene and look for something of interest like a piece of driftwood or some flowers - anything you find interesting. Remember to use the Rule of Thirds though. Now as long as you stay a little more than 2'-0'' away from your object of interest it will be in focus as will everything behind it.
Additional tips:
1) Always shoot at your camera's highest resolution. You paid for those megapixels so use them.
2) Use ISO 100.
3) Have your camera on a tripod.
4) Shoot in Aperture Priority. Your goal is to control your DOF so shooting in Aperture Priority allows you to do that.
5) Use the camera's self-timer to release the shutter.
