---------------------------------------------------------------------------------------------------------------
ZoneMinder uses zones to examine images for motion detection. When you create the initial zones you can choose from a number of preset values for sensitivity etc. Whilst these are usually a good starting point they are not always suitable for all situations and you will probably need to tweak the values for your specific circumstances. The meanings of the various settings are described in the documentation (`here <https://zoneminder.readthedocs.io/en/latest/userguide/definezone.html>`__) however if you believe you have sensible settings configured then there are two diagnostic approaches you can use.

When using xawtv etc to view the stream you are not looking at an image captured using the frame grabber but the card's video memory mapped onto your screen. This requires no capture or processing unless you do an explicit capture via the J or ctrl-J keys for instance. Some cards or drivers do not support the frame grabber interface at all so may not work with ZoneMinder even though you can view the stream in xawtv. If you can grab a still using the grab functionality of xawtv then in general your card will work with ZoneMinder.

This issue is normally down to one of two causes
1) You are using Internet Explorer and are trying to view multi-part jpeg streams. IE does not support these streams directly, unlike most other browsers. You will need to install Cambozola or another multi-part jpeg aware plugin to view them. To do this you will need to obtain the applet from the Downloads page and install the cambozola.jar file in the same directory as the ZoneMinder php files. Then find the ZoneMinder Options->Images page and enable ZM_OPT_CAMBOZOLA and enter the web path to the .jar file in ZM_PATH_CAMBOZOLA. This will ordinarily just be cambozola.jar. Provided (Options / B/W tabs) WEB_H_CAN_STREAM is set to auto and WEB_H_STREAM_METHOD is set to jpeg then Cambozola should be loaded next time you try and view a stream.
'''NOTE''': If you find that the Cambozola applet loads in IE but the applet just displays the version # of Cambozola and the author's name (as opposed to seeing the streaming images), you may need to chmod (''-rwxrwxr-x'') your (''usr/share/zoneminder/'') cambozola.jar:

Once I did this, images started to stream for me.
2) The other common cause for being unable to view streams is that you have installed the ZoneMinder cgi binaries (zms and nph-zms) in a different directory than your web server is expecting. Make sure that the --with-cgidir option you use to the ZoneMinder configure script is the same as the CGI directory configure for your web server. If you are using Apache, which is the most common one, then in your httpd.conf file there should be a line like ``ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"`` where the last directory in the quotes is the one you have specified. If not then change one or the other to match. Be warned that configuring apache can be complex so changing the one passed to the ZoneMinder configure (and then rebuilding and reinstalling) is recommended in the first instance. If you change the apache config you will need to restart apache for the changes to take effect. If you still cannot see stream reliably then try changing Options->Paths->ZM_PATH_ZMS to just use zms if nph-zms is specified, or vice versa. Also check in your apache error logs.
Also, please check the value of the ZM_PATH_ZMS setting under the Paths Options tab. It is where you configure the URL to the zms or nph-zms CGI executable. Under most Debian-based distros this value should be /zm/cgi-bin/nph-zms but in the past may have been /cgi-bin/nph-zms or you may have configured it to be something else.

Lastly, please look for errors created by the zmc processes. If zmc isn't running, then zms will not be able to get an image from it and will exit.
