Are wireless cameras a good idea?
Unless you’re talking about IP network cameras or very expensive long range microwave cameras, the answer is no for a number of reasons. First, these cameras generally deliver poor quality video, are unreliable, and their advertised range is greatly exaggerated. Second, these cameras operate within the 2.4GHz frequency range and are likely to interfere with nearby cordless phones* and wireless networks. The interference works both ways. Not only will the video quality suffer, but there’s a good chance computer connections (ie, your laptop) will be intermittently dropped from the network. Even the idea of using wireless network cameras doesn’t always make sense. This is because they’re not really wireless–you still have to run power to them! So you might as well carry the data along with the power. *Did you know that many cordless phones that are labeled “5.4GHz” use this frequency for only one direction of transmission between the base and phone while the other direction uses a 2.4GHZ
