Outdoor Wireless Security Cameras - Warn Intruders Before They Enter Your Home
If you want to ensure the security of your home, you need an outdoor wireless security camera to alert you to intruders before they can enter your house. Outdoor wireless cameras don't require cables to connect them to monitoring devices. They typically use 2.4 or 5.8 GhZ radio band technology instead to send video data to recorders or monitors. They are also housed in weather-proof and durable casings that allow them to withstand severe weather conditions as well as vandalism. Their main limitation, however, is that the radio signal is vulnerable to interference. The allowable range between the camera and the receiver may also be compromised by obstacles such as buildings that block the line of sight.
Another consideration is the power supply. If the camera will be used outside the house then you can connect it to an AC power outlet. However, if the camera will be used some distance away, you might consider buying a unit that can run on a rechargeable battery.
If you are shopping for an outdoor wireless security camera, here are some features you may want to consider, depending on your particular security needs:
One-way audio functionality that allows you to record sound and eavesdrop on people within the surveillance area. If you choose two-way audio, you can communicate with them as well as listening to them. Day or night-vision functions that allow you to record video in varying light conditions. Choose a camera with a low lux rating, since these will be the most effective in creating an acceptable image even in very dim light. Infrared functionality that allows you to take videos with satisfactory image quality even in dark or near-dark conditions. Pan-tilt-zoom functions that increase the camera's field of view by allowing you to move the camera around in a variety of angles or zoom in on a particular detail. Internet-enabled IP cameras will allow you to stream and view the video feed on your PC or mobile digital device such as a Smartphone or Blackberry. You can also set "events" and program the camera to send an e-mail alert upon detection of an event, such as when motion is detected in the monitored area.
