Connecting to a Computer (Wireless – Point-to-Point)
This is the configuration described for the receiver accessories and is the simplest connection to a
camera through the Transmitter battery pack. With all cameras having the same IP address, one
transmitter can be swapped between several cameras without further set-up. However, ensure
that only one transmitter is in use at any one time. See also FAQ 19 and 20 for advice on using
more than one transmitter at a time.
When using with other computers and network adaptors, the 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 a point-to-point configuration.
The process will be similar to that described in section 4 for installing the P7030RKT.
The computer to be used as the receiver must either have a wireless network card fitted or be
connected to an external USB network adaptor or similar device. The receiving device chosen
should have an external antenna; integral antennae and those used in USB key-fob style network
adaptors will give very poor performance.
In all cases establishing a connection follows the same steps:
• The computer must be set for a direct network connection with a fixed IP address in the
correct range and suitable subnet masking.
• The camera must be switched on and transmitting.
• Use the PC network setup functions, whether Windows or proprietary to the network
adaptor, to perform a ‘network survey’ to find the ‘argus4’ wireless ‘network’ SSID.
• Connect to ‘argus 4’ as an ‘ad-hoc’ connection.
The camera video stream is then available to be played on the computer by playing/opening the
url rtsp://xxx.xxx.xxx.xxx:554/tic04 where xxx.xxx.xxx.xxx is the camera IP address. The
configuration of the Ateme player is covered in section 6.
It is vital that no clashes of IP addresses exist in the wireless environment, and to understand that
some of the devices present may not be under the users’ control. For this reason the address
range for the Argus
®
4 wireless accessories has been chosen to be different to the normal ranges
used by common private systems. To ensure that unique addresses are used within it a
numbering scheme of FAQ 23 is suggested whereby device addresses are derived from serial
numbers to avoid clashes between Argus
®
4 transmission systems. The exception to this is with
cameras. Cameras are all supplied with the same address (10.133.1.20) so that one receiver-
transmitter pair can be used with several cameras without adjustment. If more than one transmitter
is present the camera addresses must be changed as described in FAQ 24.
