Pre recording 60 seconds at 50 fps

[White Fox 0]

My first post on here, it looks like a great forum.

 

I am looking for a PC sysem that will pre record up to 60 seconds at 50 fps.

Using between 1 and 4 PAL colour cameras.

 

It is for use in process control.

 

I tried using forum search but couldn't find anything.

 

The GeoVision 650 system I am familiar with, only allows a few seconds and not at full frame rate.

 

Has anyone got any ideas or suggestions?

hi

geovision max size of pre buffer at best resolution

on ntsc is 60 frames or 10 sec at 6fps

need to have plenty of ram for that to work

 

i am testing some linux software and it is more flexible

like in motion or zm you can make buffer ~100mb

and use 50% for pre record buffer

and you have code so you (or if you paypal to developer it can be in next version) can modify as you need

i think this group can support open software as alternative and we all have more to choose from than all this expensive proprietary closed options software

i see some nice direction like

(smart object tracking lightning detection , in motion software ) if this group

wants to unite for anyting than this is best direction to

go , and in time it will have a front end so any non linux user can use it

there is open source code C++ for Video Surveillance Software, for Windows already .. i have it somewhere if you want me to dig it up.

Dusan and Rory thanks for the replies.

I hadn't thought of using the Linux platform, our web server uses Linux and is very stable.

Dusan can you let me know how you get on with your testing, my criteria of 60 seconds pre record at 50 fps is important for our application.

Rory - yes the open source would be very interesting.

hi

what format (ntsc/pal/secam) and card are you using for 50fps on 1 channel video or is it multi channels combine 50fps ?

regular ntsc is ~30fps pal is ~25fps

 

install motion and tested my panasonic/eggcam/miropctv card

and it works fine for direct capture at 720x480 30fps ntsc , no mysql at this time did not test big prebuffer on motion software

 

my zm test is not workig / my eggcam card is not seen by zm application , mysql is setup ok , prebuffer is set ~135mb

for zm i need diffrent card , so will try my gv800 if zm / bttv can see it my linux is mandriva 10.2 2005 Le ,or i can test with my axis ip server all this linux apps are universal can use card or ip server

only is pain to setup with hardware i test (eggcam 848a chip card)

motion works fine with eggcam card and bttv driver and same card and bttv driver not on zm software ,zm is not supporting mpeg4 yet

work in progress go see motion irc and look at zm forum and ask if it can work for your application , new version for mandriva of zm is coming out so set one linux box and 1 channel card and run some test , it is only magnetism you can change it back
