Cameras capture and record feeds from select locations. Today, many companies can set up a wireless surveillance system that communicates with your mobile device. This way, you can identify a threat to your home even if no sensors are set off. You can also identify a false alarm; in locations where you get charged for summoning emergency services for a false alarm, this can save you significant expense. Another type of mobile camera feature allows you not just to receive information but also to access and control your system remotely. You may be able to control camera functions such as turning and zooming.
