10.5 Tape Catch-up Feature

The maximum time that an archive device can be off-line is based on all cameras continuously recording real time video, at the highest quality. As long as the archive device is back on-line, receiving accumulated archive data before the hard drive reaches capacity, no archive data is lost. This can be accomplished because the Hi-Q identifies or tags video to be archived. When successfully archived, the tag is removed.

10.6 Tape Archiving FAQ & Hints

•Can I search and read tapes produced from another Hi-Q?

Yes.

•Can I perform a Manual archive when in Continuous or Event Only Archive Mode?

No. You must first change Archive Mode to Manual Only via the <Data Storage><<Hard Disk>>

<<<Archive>>> menu, then follow the instructions for manual archive.

•Why can’t I write to a tape?

Ensure the tape is not write-protected.

•Can a tape be relabeled?

Before a tape is overwritten, there’s a prompt to accept the existing tape label or create a new one.

•How much video can be retrieved from tape at a time?

When retrieving video from an archive tape, 6 minutes of video is restored to the hard drive (1 minute prior to the specified start time and 5 minutes after).

•Why are there variances in the length of time it takes to search a tape?

Search time is dependent upon the type of archiving. Event Only archive tapes typically take longer.

•How can a tape be protected so that it is not mistakenly overwritten?

Depress the tape’s write protect tab.

•Why won’t the tape eject?

If the tape drive is busy or reading/writing data, the eject button is disabled. Either wait for the tape drive to complete its task or use the Hi-Q’s menu option, Eject (see Section 10.2.1).

•What happens if a Manual Archive request consists of more data that the tape has remaining?

The tape fills with data, then prompts for a new tape. The remainder of the data is transferred to the second tape.

•Does the Hi-Q continue to record and tag video for archival during a tape search?

Yes.

•Will data get lost if the tape drive has been off-line for a period of time?

The Tape Catch-upfeature usually prevents archive data from being lost. If the tape device is off-line for an extended period of time, data loss could occur.

•When can I append to a tape?

The type of archive data appending to the tape must be the same as when the tape was initialized (formatted). For example, a formatted tape containing manual archive data can only be appended with manal archive data.
