Wireless technologies
For video surveillance applications, wireless technology oers a exible, cost-ecient
and quick way to deploy cameras, particularly over a large area as in a parking lot or a
city center surveillance application. There would be no need to pull a cable through the
ground. In older, protected buildings, wireless technology may be the only alternative
if standard Ethernet cables may not be installed.
Axis oers cameras with built-in wireless support. Network cameras without built-in
wireless technology can still be integrated into a wireless network if a wireless bridge
is used.
