The prospect of drilling holes through the external walls of your home to run the power and video cable for a camera may at first seems only feasible for the most accomplished DIYer.
With a little forethought it can be remarkably simple.

Positioning of cameras
Most people want to make the camera position as discreet as possible. The modern bullet-type camera is no bigger than your small finger in length and can easily be located under or on the fascia/soffit boards where the roof line meets the wall. This location also provides good shelter from wind and rain and can be shaded from excessive sunlight. The height of the camera position will give a good area of view and minimise the risk of vandalism.
However, another advantage of this location is cabling. It is usually easy to run the cables into the loft from this position. Many houses have a small ventilation gap between the roof tiles and the external wall, or a small hole may be drilled in the fascia board to gain access to the loft.

It is usually easy to pick up mains power in the loft or at least if additional cabling is required it is now internal. Wireless transmission can be used for the video signal with the receiver being placed next to the monitor or recorder (TV, VCR, PC etc.). That's it, installation complete.
A hard-wired system can almost be as easy to install. Locate the TV aerial down-lead that may be in the loft or run down the outside of the house. It is usually possible to run the CCTV camera video cable alongside the aerial cable, which will lead directly to the TV.
A neat method of connection is to use an RF modulator. This little box changes the camera's video output to an RF output. This means you can pipe the CCTV images down the existing TV aerial down-lead and view on the TV/VCR as if it were another channel. If the house is fitted with a TV aerial distribution system, this method of connection allows the camera pictures to be viewed on all TV sets.

Addition of Switchers etc.
Consider placing switchers, mutiplexers or DVRs in the loft. This contains all the camera cabling in the loft with just one output cable to a monitor. It also hides away the recording device.
