8. What is the battery indicator showing with the EPVA?
The battery indicator behaves normally when using a Transmitter battery pack or Analogue Output
Battery Pack, although runtime is reduced when transmitting.
The battery indicator will always show full when using the EPVA. It is not measuring the vehicle or
computer battery.
9. What camera software versions do I need?
There are some compatibility issues with early cameras of type P7030. Other camera types
(P7130, P7225 etc) are fully compatible in all software versions except as described with regard to
analogue video output.
P7030 with camera software DSP 2.17 and earlier will only work with Apple Quicktime.
P7030 with camera software DSP 2.18 functions correctly but the camera address is set to
192.168.1.20 by default. This may cause problems in locations with high wireless traffic as well as
differing from the instructions above.
P7030 with DSP software Versions 3 and above function as described in this guide. This revision
also enhances image quality and camera performance.
To work with the video recording battery pack the camera address must be set to 10.133.1.20
Consult your distributor or e2v sales office for these and any further improvements applicable to
your Argus
®
4 camera.
10. Can I use other players?
Any player capable of receiving an rtsp stream should display video from an Argus
®
4 camera. e2v
recommend and supply the Ateme player as this gives the best overall performance. Other players
that may be encountered are:
Microsoft Media Player
This does not work with rtsp streams, either in current version or the apparent derivation
‘Quicktime Alternative’. It will play recorded files from the video recording battery pack with a
suitable CODEC
Apple QuickTime
A very common installation on computers, but it is a rather heavyweight consumer focused
application that can disturb other programmes on the computer. Buffering cannot be reduced
and it does not restart; this is particularly an issue with the Wi-Fi transmitter that may come in
and out of range.
RealPlayer
A consumer-focused programme which may be felt to be excessive and too invasive for the
task. It also requires additional codecs to deal with rtsp.
VideoLAN player VLC
Open source player, some buffering can be removed but not all. Useful for forwarding and
recording, VLC also has some very good image adjustment functions not found elsewhere.
M Player
Open source player, some buffering delay can be removed but not all. Useful for forwarding
and recording, but it is not totally robust when the input stream is stopped or goes out of
reception range. Much lower loading on the computer and so may be preferred on lower
specification devices and tablet PCs. There are various user interface builds available such
as MPUI. Not all variants support rtsp.
