If not already mentioned before, I would like the minimum delay between email notifications to be increased beyond 99 seconds -- which is the maximum size of the field.
The DCS-5222L PTZ camera has an entry labelled "Send next E-mail after" and can support up to 86400 seconds.
This would help cut down on constant notifications, and help avoid having Gmail (or other SMTP servers) temporarily block you for sending too many emails per day.
Even better would be to add deeper integration with mydlink as an additional option (SMTP, FTP, etc... and add "mydlink") and have this mydlink option send notifications to the mydlink app on mobile devices.
Also, the DCS-2132L should support the snapshot API other DLINK cameras have, so I can programmatically enable and disable motion detection snapshot notifications.
