Things To Consider Before Getting Security Cameras

Many people install some type of security system in their home. This can often include security cameras to provide video surveillance should something happen in the home. There are a few things homeowners should consider before getting security cameras.

Keep Expectations Realistic 

Most experienced thieves can tell a fake camera from a real one, so these aren't necessary a good use of your money. Even real security cameras won't necessarily prevent a theft, but they may at least help to identify the thief if you choose one with a good enough picture quality. To actually be able to recognize faces, for example, the camera usually needs to have a resolution of at least 40 pixels per foot. However, the more pixels a camera has, the more space the recording will take up, which can be a concern, especially if you're recording to a tape with minimal space.

Infrared Benefits

You'll need to decide on the type of cameras you get, as there are many different types, each with their own pros and cons. Infrared cameras are best for low light and nighttime use and can still provide color coverage during the daytime. When it's too dark for the camera to use a visible image, it switches to infrared and uses heat to produce what is called a thermal image. Thus, people and animals will show up as brighter spots against a dark background because of their body heat.

Wireless Versus Wired Cameras

Wireless cameras are easier to install and tend to cost less money, but wired cameras have better video quality and typically last longer than wireless cameras. Other wireless devices may interfere with the signal for the camera and result in lost video in some cases. Another concern with wireless cameras is that they are often battery-operated, meaning they'll only work if you remember to change the batteries regularly. On the other hand, wired cameras may not work if the power goes out.

Monitoring Considerations

You most likely won't have time to constantly monitor the feed of the camera. It may be good to choose one that is motion activated and only records when something is happening to avoid having to go through lots of recordings in which nothing happens. The cameras can record to a tape or send the feed to a website, depending on the type of camera you choose. Those that send to a website allow you to log onto the website from a computer, tablet or phone to check the feed and see what is happening in your home. This allows you to monitor your home from any location. To learn more, speak with a business like American Wireless Alarm Inc.
