DIY Home Surveillance System

Materials

• "PC World" magazine recommends that you use three items to create a home surveillance system: a camera, motion sensing software and software to send documented images over the Internet. You can also add a wireless network to expand your home surveillance system's reach.

  The camera is one of the most important components of your system because it captures the images. "PC World" says that many webcams cost as little as $30 and are equipped with motion sensors and remote control access, making these cameras easy to use and convenient. The drawback to webcams is that they are tied to a USB cable, which must be connected to your PC. For best results, use an IP camera. These cameras are considerably more expensive than webcams (costing approximately $350 and up) but can be used remotely and placed anywhere a network connection is available.

  If your camera's surveillance software is too difficult to use or doesn't perform the functions you require, use a third-party surveillance software, such as DeskShare's WebCam Monitor or i-Cather Sentry---both systems less than $100.

System Design

• If you have access to your home's blueprints, use them as your surveillance system design map. If you don't have plans on hand, draw a map of your home; include each room, and exterior areas of the house.

  Creating a surveillance system for one area of your home is easy, even if you are using a webcam. To check one area of the home, position one or two cameras on either end of the room and connect them to your surveillance system software. Conduct a test to ensure the motion sensors are working by asking a family member to walk through the area while you watch on your PC.

  For multiple rooms and exterior monitoring, use an IP camera. Purchase a camera that has night vision capabilities as well as remote control positioning and a remote zoom lens. This level of camera is priced on the higher side (approximately $1,000); however the best way to capture activity outside or in a dark area is to use a higher-end camera.

  The IP camera also allows for wireless network access and can be placed in multiple areas, including in exterior areas. Ideas for camera placement include over outdoor flood lights, over doors and on top of shelves. Monitor your yard by placing an interior camera near a window, pointed to the outside.
