When choosing a new outdoor surveillance security system, there are several questions you should ask yourself. The first consideration is your budget. How much can you spend on an outdoor surveillance system. Surveillance systems fall in a wide range or prices from low to expensive. Once you have figured out your budget, there are basic security equipment you will need. Most home security retail stores offer package deals that include everything you need. These include cameras, DVR and cables. You will have to supply the monitor to view the security images. These can be viewed on your home computer.
