In most setups, the ION encoders are used to stream video and/or audio to an external decoder appliance or to a central video management system (VMS). From there, the streams can be viewed «live» (in real time), recorded or both.
There are deployment scenarios that require the ION encoders to record audio/video content to local storage instead of recording on an external video management system (VMS). There are also situations where the encoders simply cannot reach the VMS for a period of time. There may be temporary network disruptions, the video management system may be undergoing maintenance, or there may be an attack on the security system in progress.
If external conditions prevent the ION encoders from streaming its media content when it is configured to do so, then the ION encoders can record the streams locally instead. Once the situation returns to normal, the recorded content can then be retrieved from the ION encoders. The storage capacity is limited, but depending on selected quality, a few days or so of content can be recorded at a time. On top of that, instead of having it on continuously, the edge recording functionality can be triggered by external alarms, events, or motion detected in the analyzed scene, thereby extending the effective time period covered by the available storage capacity.
In order to have access to the edge recording feature please make sure that the recording module is initialized during the bootup sequence of the device. This can greatly impact the startup time, so it shouldn’t be active if not necessary!
Edge recording on the ION encoders can be configured through the device’s web application or the ION API. To view or change the recording settings from the web management interface:
• Open the device’s web application. Enter your use name and password;
• Click on the Configuration section;
• In the configuration page, click on the Recording tab;
The Storage section in the Recording tab offers an overview of the total and available capacity and tools to diagnose, repair and clean the storage card. Make sure to use a 2GB to 32GB microSD of Class 6 or above, formatted in FAT32 or EXT3!
Further down in the Recording tab the user can set all of the parameters related to recording, like the video input, recording mode (continuous or trigged by external alarm, event or motion detection), retention time and grooming. Video recording can be configured to simultaneously record an associated audio input stream as well. That being said, the system does not allow the user to ONLY record audio content, it can only allow to record audio in addition to a video stream. This can be set in the Configuration > Video In tab.
The Web Interface allows the user to view all recorded files and download them to a computer for local playback using a software media player. The interface also allows the user to lock files to prevent them from being groomed or to manually delete unwanted media files. This is accomplished in the Recording section.
