Wireless camera systems have a very high ‘coolness’ factor (wireless is the ‘in’ thing these days ya know), however, there are three major drawbacks that need to be considered before purchasing a wireless camera. In fact, I often tell people that they should consider a standard ‘hard-wired’ security camera first, and if possible avoid going wireless. Here are five problems associated with wireless security cameras:
- Most wireless systems are on the 2.4 GHz frequency band which is crowded with tons of other devices ranging from wireless PCs to cordless phones. This makes for possible interference with the reception of the video signal.
- Weather events such as rain, snow, and even wind can wreak havoc with wireless signals.
- Terrain features such as hills, buildings, and walls can reduce signal strength
- Limited focal length lense availability. The transmitter adds cost and bulk to the camera, so most manufacturers of consumer wireless cameras only offer them with a standard wide angle lens. If you want a varifocal or longer focal length lens, you may be out of luck.
- Anyone with a 2.4 GHz video receiver can possibly pick up your video signal from that wireless camera used in your home. The manufacturers don’t really have a standardized encryption for most consumer wireless security cameras.
