Setup camera and such

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install vlc
sudo apt-get install hostapd
sudo apt-get install dnsmasq

edit the file /etc/network/interfaces and replace the line "iface wlan0 inet ..." with:

iface wlan0 inet static
  address 192.168.42.1
  netmask 255.255.255.0

Edit the file /etc/default/hostapd and change the line:

DAEMON_CONF="/etc/hostapd/hostapd.conf"

edit the file /etc/hostapd/hostapd.conf

interface=wlan0
ssid=TacticalSpaceLab
hw_mode=g
channel=6
auth_algs=1
wmm_enabled=0

Change IP and start hostapd

sudo ifconfig wlan0 192.168.42.1
sudo service hostapd start

Maybe it doesn't work. Using EDIMAX interface? Try this version of hostapd (via Dave Conroy)

wget http://www.daveconroy.com/wp3/wp-content/uploads/2013/07/hostapd.zip
unzip hostapd.zip 
sudo mv /usr/sbin/hostapd /usr/sbin/hostapd.bak
sudo mv hostapd /usr/sbin/hostapd.edimax 
sudo ln -sf /usr/sbin/hostapd.edimax /usr/sbin/hostapd 
sudo chown root.root /usr/sbin/hostapd 
sudo chmod 755 /usr/sbin/hostapd

Set up dnsmasq to give clients DHCP-based IP addresses configure /etc/dnsmasq.conf

interface=wlan0
dhcp-range=192.168.42.50,192.168.42.150,12h

restart dnsmasq

sudo /etc/init.d/dnsmasq restart

Start video share

sudo modprobe bcm2835-v4l2
cvlc v4l2:///dev/video0 --v4l2-width 1920 --v4l2-height 1080 --v4l2-chroma h264 --sout '#standard{access=http,mux=ts,dst=0.0.0.0:12345}'
