I want to buy a wireless security system outside. Suggestions? I do not want to spend a fortune, but I'm not cheap either. Does anyone know of some decent wireless systems with around four cameras than I can stand outside and view either of my TV, computer or a monitor that comes with the system? Any help is appreciated.
Firstly, if you are looking for a good usable image you probably want to stay away from the dirt being schlepped off shore on geeknet and superstores.
There are a number of ways you can go, as the camera display on television there channel insert available that overlay your video onto a channel on your cable TV. Alternatively UHF wireless transmitters, but the neighbors will also be able to see your video snippits (which may or may not be a good thing, depending on your opening)
Another method is to use a network DVR which you can access your local network (which can also be accessed remotely if you have a static IP address). If you do not already have one, you will need a multi-port router for this to work. Expensive than 30-150 dollars.
You can also obtain an independent monitoring system with a video switcher / sequencer or quad screen. It does not record if you connect a recorder, but if you want to see that this could be the solution for you. If you take a look back the history of my answer there was a similar question when I went over in detail the differences between switchers, multiplexer, quad and DVR. I also wrote an article on the camera for some time back, it's pretty old, but most of it still applies. There is more information that can help on my website to http://www.keepsafesystems.ca.
I hope this helps you in your approach.

The starting point of any system of closed circuit television camera is. In simple terms, a camera is a light sensitive device that converts the particles of light into electrical impulses, however, there is a big difference in the quality of cameras available to the consumer. The factors that differentiate the different cameras understand that they are color, black and white, light sensitivity, image resolution and image transfer technology. Consumers should also consider the advantages and disadvantages of each different camera technologies and decide who best understands their needs and personal goals.
In the past, color cameras have been both very expensive and lack luster to their image performance, compared to cameras black and white. The new technology is now closer to these innovative technologies in both price and performance scale. The current differences between the two technologies are almost entirely limited to light sensitivity and responsiveness to light.
Light sensitivity is measured in lux. More LUX rating, the more sensitive to light. It is important to bear in mind that even the top rated cameras are limited by the technology of the day and visibility conditions present at the time of surveillance. Although great progress in low-light surveillance continue to be under way, the image quality in low light situations rarely conform to the monitoring light.
color cameras, although much more attractive on the outside compared to their counterparts in black and white, generally have lower sensitivity to light of a black and white camera. Another advantage of black and white cameras on color cameras is its ability to "see" infrared light, which is invisible to the human eye. You can test this by aiming a TV remote to a standard black and white camera while watching the monitor, the flashes you see are flashes of infrared light. The advantage of this Beco.
