900 MHz VS 2.4 GHz Confusion

The popularity of wireless color video monitors is growing exponentially as a necessary device for parents to help protect both infants and older children. Unfortunately, many families are extremely disappointed when they learn from experience that the monitors can be rendered useless by radio interference that may be generated both inside their home as well as from the external environment. Other common household devices such as microwave ovens, portable telephones, and wireless computer networks can wreak havoc on a wireless monitor. This is largely because many of these devices operate at 2.4 GHz as does most of the wireless monitors on the market today. The resulting conflict can be unpredictable but at

its worst none of the devices work properly. Below, we have listed some of the strengths and weaknesses of each technology in the hope that customers can make the right choice for their needs.

	2.4 GHz
	Strengths		Weaknesses
	Cameras typically can send the signal over a greater distance than 900 MHz devices. The 2.4 GHz signal can more easily penetrate walls. A larger variety of cameras are available that operate at 2.4 GHz 2.4 GHz monitors tend to be able to handle a larger number of cameras.		Many competitive devices operate at 2.4 GHz and may cause conflicts. The nature of any interference can be unpredictable. Other household devices may cause interference with the monitor but at other times the monitor may render a computer network inoperable.
	900 MHz
	Strengths		Weaknesses
	As more household devices are designed to operate at 2.4 GHz there are fewer devices that create conflicts so they tend to experience less interference. The technology has been perfected and has proven to be very reliable. A transmission range of 300 feet is generally standard. Units are less expensive than 2.4 GHz devices.		The transmission range tends to be shorter than 2.4 GHz devices. Monitors seem to be limited to handling 2 cameras simultaneously. Fewer choices are available since most manufacturers are moving to 2.4 GHz.
