Suggestions for Surveillance Security Outside a Home

Check Camera Resolution

• The resolution of the image your outdoor surveillance equipment can capture determines how clear images will be. Low-resolution cameras may show the basic shape of an intruder but won't provide clear enough details for positively identifying a suspect. Higher-quality cameras should offer higher resolution values as well. Expensive cameras that can detect movement or pan to follow movement won't be useful if they can't capture clear images of the actual criminal. Ask to see real images captured by the camera in different conditions instead of just relying on resolution numbers.

Night Vision Capabilities

• Infrared sensors and night vision capabilities allow your outdoor surveillance equipment to capture images when little light is available. Normal outdoor cameras rely on sunlight for illumination and are unable to record clearly during the night, when most property theft or breaking-and-entering crimes are committed. New developments in infrared and night-vision technologies have made powerful night capture cameras available for home use. Another option is to install motion-activated security flood lights to give cameras enough light to record an intruder and add an element of surprise.

Measure Electrical Interference

• Many outdoor surveillance cameras and digital video recording equipment operate on the same frequencies as cell phones and other electronics, making them susceptible to interference. Installing your new outdoor surveillance system may become a major frustration if electrical interference causes a scrambled or static-covered image. Equipment for testing the amount of interference at different points around your home can be rented or purchased from a electrical supply company, or you can hire a professional to take readings and recommend the best locations for installation.

Wireless Cameras

• Wired cameras require the installation of hundreds of feet of cable for transmitting images back to a receiver, while wireless camera require only a power connection. Even well-hidden wired cameras can have their cables cut, preventing a criminal stealing your car or entering your home from being recorded. Wireless cameras may use a USB connection that allows you to record remotely with special software on your computer, or a properly equipped digital video recorder that connects to a television for live viewing. Wireless units are also easier to install in difficult-to-reach areas.
