Connecting to a Computer (Wireless – Networked)
This configuration enables several cameras to operate at once and a combination of wired and
wireless cameras to be operated together. Additionally the display computer may also be
positioned away from the receiver potentially doubling the range. A router offers some
performance benefits in managing the network in a busy wireless environment. It also allows wired
camera connections and may allow other networking functionality or internet access for example.
This configuration depends primarily upon the selected devices and is not within the scope of e2v
product support. The information below is general guidance to allow competent users to operate a
system in the wireless networked configuration.
The adjustment of these settings in the module is different across the various versions of module
firmware. Contact e2v for assistance. In some instances familiarity with TELNET access is
required as some versions of module do not have a web interface.
Use of a wireless router transfers control of the transmitter frequencies to the
router. Do not attempt this mode of operation unless certain that the system will
be legal at all times by using the correct router settings. The transmitter is under
100 mW 20 dBm effective output power.
Operation on channels 9 – 13 (above 2454 MHz) is not
permitted outdoors in France.

Là où utilisé dehors, creuser des rigoles seulement 1 – 8
(2400 - 2454 MHz) peuvent être employés.

There are two network devices present for each transmitting camera; the camera video output
itself and a transmitter control module in the transmitter battery pack. The configuration set for the
transmitter control module as shipped from e2v is for an ad-hoc (point to point) network using fixed
IP addressing.
The settings in the transmitter control module must be changed to work within a router controlled
‘infrastructure’ network. It is also recommended that DHCP address allocation be used for the
control module. Additionally the camera(s) and the router must be set to use a compatible IP
address range. Note particularly that cameras do not use DHCP address allocation. This includes
any wired cameras and other devices connected to the same router.
A static address may be set for the control module, but note that this does not set the camera
address.
Do not use an address that is the same as any camera, the router, the router DHCP range or any
other fixed IP device on the network.
All wireless devices must use the same ‘SSID’ as the router. The SSID is best chosen to reflect
the router or network identity itself and not ‘argus4’ to avoid confusion with any point-to-point links
in the vicinity.
If encryption or MAC address locking is employed as a security measure, this must also be set at
the transmitter control module and the camera MAC address must be permitted access to the
network.
