| Most computers now days use SSD drives which are wonderfully fast but do not last forever under heavy use. Recording video all the time uses a lot of disk sectors over and over again slowly reducing their lifespan faster than they would normally. I would recommend that video recording be done to external drives, preferably of the spinning platter type, or at least SSDs that are not internal to the Mac and therefore irreplaceable. Since the plugin instances each have their own recording directory you could easily place each video camera on a separate external drive if you wished. I would not recommend recording video to the internal drive of a modern Mac. | Most computers now days use SSD drives which are wonderfully fast but do not last forever under heavy use.

| + | =====Script Handlers:===== | ||
| + | ====Stream Stalled Handler:==== | ||
| + | All Camera types implement a script handler that is called when the stream stalls. It is passed a count of the attempts to recover since it went down. This way you can ignore a single stall that is recovered by closing and opening the connection again but can take other measures to recover if the camera does not recover on the first try. | ||
| + | |||
| + | Use the “Insert...” toolbar item on the Edit Interface Script window to insert the template for the event. | ||
| + | <code> | ||
| + | (* S T R E A M S T A L L E D | ||
| + | |||
| + | This handler is called when a camera stops sending frames. StallCount is passed that is the count | ||
| + | of stalls in a row. This way you can tell if a camera is not recovering and take other action like | ||
| + | rebooting or power cycling it if needed. The count will increase until the interface is restarted or | ||
| + | the camera starts responding again. | ||
| + | *) | ||
| + | |||
| + | on streamStalled( stallCount) | ||
| + | write log "Attempted to restore camera " & stallCount & " times." | ||
| + | end streamStalled | ||
