The following instructions apply to the GardePro Baby Monitor B3.
1) The maximum distance (abbreviated for MD) between the monitor and camera is 3000ft in open area without any obstacle.
2) Check for any obstacles between the camera and monitor and make attenuation estimates
|
Typical obstacles |
Attenuation factor |
Fast division factor (FDF) |
|
a concrete thick wall / floor about 9 inch |
16~32 |
20 |
|
a concrete thin wall about 5 inch |
4~8 |
5 |
|
a big tree or bush with shadow diameter of 15ft |
4~8 |
5 |
|
glass door or window |
2 |
2 |
|
a TV or computer |
1.5~2 |
2 |
|
a refrigerator |
1.5~2 |
2 |
You must consider all the obstacles between the two units, include each wall or floor, each tree or glass window, etc.
3) Estimate the actual communication distance (ACD).
ACD=MD/FDF1/FDF2/.../FDFx
Example1:
If there are a thick wall and a thin wall between them, you can estimate as this.
ACD=3000/20/5=30 ft
Example2:
If there are a thin wall and a glass door between them, you can estimate as this.
ACD=3000/5/2=300 ft , you can use the monitor in your garden or yard in this distance.
