Hi,

I can connect to my SD Card in the CCTV by '192.168.1.45/sd' as
address in the Google Browser. Then i have to give an password and i
am in.

The only thing i can do now is browse and download the SD Files.

I would like to have the possibility to delete INDIVIDUAL files/dirs
on that SD card, the only way i can delete files now is by formatting
the SD card.

How can i do this?

TIA



You should download all the files off the camera,
so that it can be re-formatted at any time. The purpose
of that SD store, is not to make a "curated" collection
of videos. It's a replacement for a tape drive,
and should be offloaded and the file content
managed on a real computer. When the
"tape is full" and all content is copied off,
you reformat it, which is like putting a
fresh tape in it.

You should also check to see if the camera has
a setting to delete the oldest file and write
the next one in its place. That would be the
logical equivalent of a CCTV equipped with
continuous loop tape recorder. With those, you
only look at the tape, after an "incident". If
the SD is big enough for 7 days of video, then
you'd review the continuous loop within 7 days
of an event.

In terms of the mechanics, a web server can be set up
to support just download, or download and upload. If
the web server inside the camera supported upload,
you could upload a zero-length file with the same
file name as the one in question, and recover the
space. But the file name would continue to exist
until it was formatted again. The camera has no logical reason
to support this.

A thief could steal all your cameras, you would
lose all the SD cards inserted in them, and you'd
have nothing.

If a thief suspected the cameras were Wifi,
he could jam the 2.4GHz band (devices are
available), then steal all your cameras. And
there would be no log at all, no pictures
of his pretty face, later.

While the average perp isn't all that clever,
some of them are as clever as you. They know
just enough about electronics, to do a successful
B&E. They know the police department response time,
an alarm does no good, and if they know you use
Wifi cameras, you could be completely defenseless.
And only have fingerprints later as evidence.

Good idea about that it will overwrite the old files when it gets full.
Maybe it will. Haven't tested that because it's new. Will take another
few days before it's full. We'll see.

When this works then i do not need to delete files manually.
But there is still the technical curiousity ...

Tried to map it, but get error messages.

Thx.
