an equilateral triangle is intended to alert the
user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that age"
within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
● The rotation angle of this camera is increased to
enable installation at a wider variety of locations. When
the lens is at the wide-angle position, and tilted at an
angle close to +/-80 degrees, a part of the camera
may come into view on the screen depending on the
rotation angle. When this occurs, adjust the field angle
accordingly.

msec. If the alarm signal is short, it may not be
recognized.
You can configure the menu to set the alarm to
sound when contacts short circuit (MAKE) or
when the contacts are open (BREAK). (Pressure
resistance lower than 16V, 30 mA)
• This terminal has different polarities. The output
voltage at the positive terminal must always be
higher than the output voltage at the negative
terminal. Otherwise, the circuit may be damaged.
