Patrol Car






Data, video and audio collected by the inspecting personnel are
transmitted to the patrol car via the secured wireless mesh network.
Patrol Car then transmit the information to the Control Center via
Internet
Virtual Private Network (VPN) is used to protect data transmit over
Internet
Patrol Car and Mobile Wireless Stations are 2 or 3 km away.
Management Software in the Patrol Car
manages the Mobile Wireless Stations and
portable video devices used by the
investigating personnel.
Sensitive data is protected by utmost
security mechanisms including encryption,
and authentication.
Mobile Station






Stored in unbreakable, watertight and corrosion proof
outdoor enclosure
Battery charged and last for two hours.
Advanced mesh feature allows all
access points to be self-configuring
and self-recovering, such that no
configuration and maintenance
is required
Flexible 5.8GHz/2.4GHz dual radio design
Could be carried or pull by wheels.
LED display connection status
Portable Wireless Network






The wireless network is formed
by a group of Mobile Wireless Stations.
Network can be quickly deployed and easily
torn down
No power supply or access to public
network is required
Self-configuring and self-recovering, zero
configuration and maintenance is required
Ideal for extreme whether condition
Rechargeable battery can run
up to 2 hours
Benefits of Mesh Architecture




Self-Configuring and Self-recovering, automatically
identifies most efficient routes
In the event that any AP becomes not available, adjacent
APs recalculate and establish links with each other
Dual-radio design allows one radio focus on Wi-Fi
access and other radio to perform mesh related tasks
Minimize configuration mistakes and maximize network
uptime

Control Center
Control Center







Information gathered by the patrol car is transmitted to the remote
control center via Internet (3.5G).
Virtual Private Network (VPN) is used to protect data transmit over
Internet.
With the GIS map, it can show all the patrol car position, direction
and speed.
Retrieve all the instance video on the patrol car (including
investigating personnel)
Save all the driving records for retrieving in the near future
Control center can use far-end method to control the recorder’s
direction and zooming in the patrol car
Video transmit resolution is D1(720*480) and 10 shots per second
