From this Recordings panel the recording to play is selected. Also from here, and after a recording has been selected, the events from the recording can be listed.

From last specifies the maximum age of the recordings to show in the list. From last 40 days returns the recordings made over the last 40 days. Include types lets you show normal recordings (CNS), and also recordings that had the A/V format changed during the day (.f##), and error recordings (.e##) which, when resumed during the day, were found to be too corrupt to automatically repair. The ## is a number between 01 and 99.

Press Refresh to reload the matching files.

Select a recording. The main status of the recording is shown in the status box. This includes the start and end times. There may be one or more gaps in the recording depending on the recording's schedule. The day of the recording (Sun,...Sat), the timezone bias, and if DST or standard time. The recording file size, whether the recording is active or closed, the number of events, and the time of the last event.

Pressing the Play button while a recording is selected starts playing that recording from the time showing in the play clock (under the Play button). If the time is not within the range of the recording, the next valid time within the recording is the time at which play starts.

Press Show events to switch the list to events mode. This is the list of all events for this recording. It shows the motion detect windows (MD 12345678), the digital inputs (DI 012XxPAT) that caused the event, and the actions taken due to the event notification.

When an active recording (today's recording) is selected, press the Refresh button to get any newly-processed events. It can take up to 15 seconds before new events commit to disk. Events won't be sent to the client until they are on disk.

Select an event at which to start play. The time of the event is copied to the play clock, less two seconds: if the event shows a 11:00:00 time, the time in the play clock is 10:59:58.

Press the Play button. The recording Transport panel appears. Play starts soon after.

On either side of the Show files button is a filter selector. The left filters by motion detect window (MD1 to MD8) and the right by digital input (0, 1, 2), including event extensions such as line crossing, field intrusion/intrusion detection (X and x), PIR (P), audio (A), and by-trigger (T). The trigger filter is an inverse filter: set it to exclude events which are only T events. Set to M and D to return an unfiltered list of events. Press the Refresh button to use a new filter selection.

For example. To return only a list of events that have motion detected in MD window 3, press the left filter button (currently M in the image below) until it shows 3. Press Refresh. The list returned includes only those events which have at least a 3 in the MD section. (A single event record may have multiple MD and DI hits.) To limit events to only line crossing (or field intrusion, also known as intrusion detection) on Hikvision cameras, pick the small-x from the D selections.
