ZoneMinder is a free, open-source software application for monitoring via closed-circuit television - developed to run under Linux and FreeBSD and released under the terms of the GNU General Public License (GPL).
Users control ZoneMinder via a web-based interface. The application can use standard cameras (via a capture card, USB, FireWire etc.) or IP-based camera devices.[3] The software allows three modes of operation:[4]
- monitoring (without recording)
- recording after detected movement
- permanent recording
The application supports multiple cameras, reviewable simultaneously. Recording starts when the application detects changes between camera frames; one can select zones within field of view that the software will ignore.[5] ZoneMinder supports cameras compatible with ONVIF standard.[6] However, relative difficulty of configuration is - along with limited support for other languages than English - counted among ZoneMinder's weak points.[4] This is underlined by lack of straightforward documentation.[7] Filip Palian reported in 2008 that ZoneMinder contained security loopholes allowing unauthorized remote control of cameras, basic authentication (for example, .htaccess on Apache) should circumvent such issues.[8]
