zoneminder with multiple Somagic CAMs

Februar 9th, 2017

(addition to this article)

3 CAMs on different USB BUSs:

# lsusb |grep SMI
Bus 008 Device 095: ID 1c88:003c Somagic, Inc. SMI Grabber (EasyCAP DC60+ clone) [SMI-2021CBE]
Bus 003 Device 008: ID 1c88:003c Somagic, Inc. SMI Grabber (EasyCAP DC60+ clone) [SMI-2021CBE]
Bus 001 Device 010: ID 1c88:003c Somagic, Inc. SMI Grabber (EasyCAP DC60+ clone) [SMI-2021CBE]

Info: if you connect two SMI Grabber Sticks on the same USB-Bus, the bandwidth will not be enough. You need somagic-capture with multiple device support!

Init your devices:

retcode=0
while [ $retcode -eq 0 ]; do
	somagic-init
	retcode=$?
done

define your cams with xinetd:

/etc/xinet.d/vid0:

service vid0
{
	disable = no
	socket_type = stream
	port = 7100
	bind = localhost
	protocol = tcp
	wait = no
	user = root
	server = /usr/local/bin/somagic-capture
	server_args = -d 1 -p
	type = UNLISTED
}

/etc/xinet.d/vid1:

service vid1
{
	disable = no
	socket_type = stream
	port = 7101
	bind = localhost
	protocol = tcp
	wait = no
	user = root
	server = /usr/local/bin/somagic-capture
	server_args = -d 2 -p
	type = UNLISTED
}

And so on… (-d 1-9 sets the device number)

Thanks!

Define the needed count of fcgiwrappers in /etc/init.d/fcgiwrap to view more than one cam at the same time:

FCGI_CHILDREN="3"

Info: 3 means one client (Browser/App) can view 3 cams at the same time or 3 clients can view one cam. If you want 3 clients (PC-Browser, smartphone and tablet) can view 3 cams at the same time, then you need 3*3=9 child’s!

Thanks!

install ZoneMinder:

Thanks!

configure your cams in ZoneMinder:

https://yourdom.tld/zm/ create Monitors for every cam:

  • Source Type: libvlc
  • Source Path: tcp://localhost:7100
  • Options (?): –demux=rawvideo,–rawvid-chroma=UYVY,–rawvid-width=720,–rawvid-height=576,–rawvid-fps=25,–rawvid-aspect=4:3
