Passive Mode
If NetCam SC is behind a proxy server, enable passive mode. If
you are unsure if you need passive mode, it is usually safe to enable it
anyway.
Timeout
If the FTP process hasn't completed within the time specified here,
the Express 1 will attempt to restart the process.
Default: 120
UPLOAD VIA SMTP (EMAIL)
If you prefer the event-triggered image captures be e-mailed, select
this option. If you've enabled a large number of images, this can add up
to a large e-mail attachment.
Mail To
Specify the e-mail address you prefer NetCam to send the images to.
Mail From
Specify a "from" e-mail address. This can be created.
TRIGGER SENSOR CONNECTOR
The I/O connector contains one opto-isolated trigger input and one
relay connection.
Pins 1 and 2 are an opto-isolated input, providing 2500VRMS
isolation. To trigger, apply positive voltage to pin 1, and negative or
ground to pin 2. The trigger voltage should be 3.5VDC to 12VDC,
1.4mA minimum. You may connect directly to a 12VDC alarm
system, door sensor, etc. but the polarity must be correct or you risk the
possibility of false triggers.
Higher voltages may be used as long as the power used by the
internal 1.5K resistor does not exceed 1/4W. Here are some resistor
values you can use in series with pin 1, to trigger from voltages higher
than 12V:
12V to 16V = 2.7K
16V to 26V = 5.1K
Additional values can be calculated from:
Resistor (ohms) = (Input Voltage) x 357 - 1893
