I am looking for a high resolution digital surveillance system.

The requirements are:

- Digital harddisk recording (standalone or pc-based)
- Minimum 4 inputs - should be scalable
- needs support for connecting different kind of cameras (such as
normal light, low light)
- needs playback, seek and zoom-in function for recorded content
(simultaneous to recording of course). Best would be client-access
software from pc's over network.

-> Requires HIGH-resolution recording so that as many details as
possible are visible during zoom-in. Quality needs to exceed pal/ntsc
resolution.

Might require and can run with LAN-cameras, as regular
cable-fbas-cameras only support tv resolution (as I guess). Must
record high-res with >= 5 frames per second.

Marcelsci,

   The Higher Resolution 1.0 MegaPixel and above is the direction the
surveillance industry is moving...however at this time, it is still
unavailable.

    The IP cameras that you are mentioning are not generally
recommended, due to the compression that takes place in the camera. 
Most of these cameras will reduce the Raw analog video into a MJPEG
format, which generally reduces the quality, for less network overhead
while travelling over a network.  This amounts to lower quality video.
(remnants and stereotypical jpeg compression woes).

    Even after the Higher Resolution Cameras are produced, the video
capture world is not ready.  We work closely with many of the foremost
providers of CCTV capture cards, and even the latest offerings from
each manufacturer, are limited to just over 640x480 capture(NTSC).

    To compensate, you might use a good high-Resolution CS mount
camera, and have it zoomed in to what you need to see, then use a few
more cameras.  I would recommend our Alnet Style software, as it has
the most remote access features (Client software, IE Remote Viewing,
PDA Remote Viewing, Cell-Phone Remote Viewing).
