Congratulations on your purchase of this PRO-761 from Swann ! You’ve chosen
well: we think this is one of the finest CCTV video cameras available. The PRO-761
is great for monitoring a wide open space whilst maintaining a high level of detail,
even in low-light situations.
Placement Guide
The PRO-761 has a 3.6mm wide-angle lens built-in which allows it to see almost
80 degrees horizontally. What does this mean for you when placing it?
• You will be able to see a really
wide area . If it’s mounted high up
in a square corner, you’ll probably be
able to see along both walls. You’ll
be able to monitor a large area with
only one camera.
• Things may look further away than
they really are. Anything further
than a few meters (ten feet or so)
from the camera may appear to be
too small for the level of detail you
require.
• Vertical and horizontal lines might appear curved when they near the edge of
the camera’s view. This is normal, and it’s the side effect of cramming so much
viewing area onto one screen.
The PRO-761 is great for monitoring rooms or areas as wide as, or wider than, they
are long. For really wide areas, you may need a second camera.
Typically, it is best mounted in a corner looking across and down into the room,
so that it can look over intervening obstacles. The higher the ceiling the camera is
mounted on, the more it will be able to see and the harder it’ll be for an intruder
to access the camera or interfere with it.
Tips:
• Try to aim the camera at an area which is evenly lit, as objects or people in shadows
near brightly lit objects are very hard to see.
• It’s better to have the camera in the shade looking into the light than vice-versa.
• Avoid having bright light sources in your image. This includes the obvious (such as the
sun or an artificial light source) but also things such as reflections. Cars are notorious
for reflected light sources, as are buildings with a lot of windows, mirrors and so forth.
