Wireless security cameras use wireless technology and are placed anywhere easily without the hassle of running cable. The cameras do have some drawbacks, such as signal loss. A few factors can help solve this issue, including getting equipment with the right frequency for the space being monitored.
Other drawbacks are privacy concerns, as someone with a monitor can pick up networks from baby monitors, security cameras and business surveillance systems. One solution to this problem is to purchase more expensive equipment that is encrypted with a secure feed from one device to another that's harder to crack.
