Range Overview
The reception range of your video baby monitor system depends on several factors. The factors with the most impact on useable range are Transmission Strength, Geography, and Power, all of which are outlined below:
Transmission Strength -
The transmission power of a wireless camera is the primary factor in determining the expected range of any system. Less expensive units will often save money by utilizing a less powerful and less expensive transmission system.
If the distance between where you plan to have the camera and receiver is short, then a less powerful unit will most likely work fine and save you some money as well. On the other hand, if the distance between the monitor and camera is great, then you will want to get a system capable of longer transmission ranges. For example, if the camera is to be upstairs and the receiver downstairs, or if your house has especially thick walls you will want to go with a more powerful unit. Another case is if your area has high levels of interference, you will want the additional power to "punch through" that interference.
Geography -
There are two defined distance ranges specified for video baby monitors; they are "clear line of sight" and "obstructed".
Clear Line Of Sight refers to a flat open area, where there are no obstructions (such as Wall Mounting Spotlights Suppliers a football field). Usable distance will be much greater when the camera and receiver can visibly see each other and there are no obstructions.
Unfortunately in the real world, most people use video baby monitors in the home, where the environment is rarely designed as a football field. Fortunately, all the frequencies used by video baby monitors are specifically designed to penetrate walls, ceiling, floors,and other obstacles that are commonly found between the receiver and camera. While these signals can pass through solid objects, it does come at the price of reduced range. The more barriers a signal must penetrate, and the denser those barriers are, the shorter the usable distance becomes between receiver and camera.
Obstructed distance is a rough estimate of the range you can expect when the space between the camera and receiver is obstructed by walls, ceilings, floors or other obstacles. This range will vary depending upon the number and density of obstacles the signal must penetrate in the particular environment.
