Wireless IP Camera Setup
Due to their flexibility and cost savings, wireless IP cameras are an interesting alternative to wired networks. For example, a wireless IP camera, like the Axis M3113-R, in a bus can be accessed live from remote locations.
Or, historical buildings protected by the Heritage Act may not allow standard network cables to be installed thus only allowing a wireless setup. Wireless IP cameras signals can go through most media such as wood and concrete.
Wireless IP Camera Setup Considerations
If a wireless solution needs to be implemented because fixed data connections are unavailable or too costly to install, the following things need to be considered before proceeding:
- Obstacles such as buildings and forests will damper the wireless signal and limit its reach. The fewer the obstacles, the longer the distance that can be bridged.
- Most wireless solutions specify the maximum bandwidth but the real bandwidth required depends on the distance and obstacles and may be half or even only 10 percent of the maximum.
- Use a spectrometer to check what other frequencies are already in use. The level risk for interference depends on what other wireless networks are installed in the area.
- Wireless sends data out into the open air. The security of the connection requires use of appropriate security protocols such as 802.1X. However, adding security protocols normally decreases performance.
- Wireless networks replace cables but power is still required at both ends.
