Potential sources of interference in the 2.4GHz ISM band: Existing previously installed 802.11 networks can also cause interference. The two most common sources of wireless network interference are wireless telephones and microwave ovens. Interference can slow down a network significantly and reduce its range as well. The 802.11 wireless standards communicate in the 2.4, 3.6 and 5 GHz frequency bands. The other thing to check for is potential interference with the Wi-Fi network’s frequency range. So if you have tinted glasses anywhere between WAP and the camera, you can expect a drop in signal strength. Tinted glass panes carry metal constituents.When placing an IP camera make sure the elevator does not come between the camera and the Wireless Access Point Elevators block Wi-Fi signals to a great extent.

If the walls are made of non-porous materials, your wireless connection may have a shorter range or a slower speed.Therefore, wireless surveillance solutions do not guarantee connectivity between floors of buildings and between thick reinforced concrete walls The following facts should therefore be kept in mind: However, materials such as brick, plaster, cement, metal, stone, and double-glazed glass may cause problems. Materials such as drywall, plywood, other kinds of wood and glass can be easily penetrated by wireless signals. However, in reality, some walls are thicker or use reinforced concrete and may block some of the signals. In theory, Wi-Fi signals are capable of passing through walls and other obstacles relatively easily. The first thing to do is to check the construction of the walls.

It is very important to be aware of these impediments and see how they could affect the installation, before going in for a wireless solution. While installing Wi-fi solutions, a user may come up with a few impediments specifically w.r.t the range and reception.
