Q How can I keep Network Camera as private as possible?

A Network Camera is designed for surveillance purpose and has many flexible interfaces. The user authentication and special confirmation in installation can keep Network Camera from unauthorized access. You may also change the HTTP port to non-public number. You can check system log to examine any abnormal activities and trace the origins.

Q Why can I see image files when I use dir in FTP even if the alarm is not triggered? A Every time Network Camera starts, it will capture the images as vpre.jpg. If there are previously saved image files that are not retrieved, Network Camera will keep them until they are accessed.

Q How will the stored images be processed if Network Camera loses power?

A If user has defined the snapshot interval, Network Camera will capture images periodically. Once the pre-defined condition is match, the pre-alarm images will be kept and the current images will be saved. The subsequent images will be stored as post-alarm stage. User may retrieve these files either by downloading via FTP or direct Network Camera send them in e-mails. That means after monitoring conditions are met, Network Camera will keep these image files until user retrieval even if power is lost.

QIf I set Network Camera to send e-mails of images whenever the conditions are met, will my e-mail account overflow?

A It is recommended to use transient state rather than steady state. For instance, use
