For BL-C131A: Notes About Wireless Communication

The radio wave range may decrease depending on the surrounding
environment or existence of obstacles. If obstacles such as the following
are placed between a camera and a router, radio waves will weaken.
Therefore, even if the distance between the camera and router is short, the
frame rate may decrease or images may not be displayed.
• A metallic door or shutter
• A wall with an insulation material that contains aluminum foil
• A wall made of tin
• A wall made of concrete, stone or brick
• Fireproof glass
• Several walls separated by open space
• A steel shelf
In the example below, wireless communication between the camera and
the wireless router is impaired due to steel doors or reinforced concrete
walls between the camera and the wireless router.

PRIVACY Button

Privacy mode allows you to protect your privacy by hiding the lens inside
the camera, preventing camera images from being seen. You can turn
privacy mode on by pressing the PRIVACY button on the front of the
camera.
When privacy mode is turned on, the PRIVACY button (which also serves
as the camera’s indicator) changes from green to red to let you know that
privacy mode is activated. To turn privacy mode off and allow the camera
to be accessed, simply press the PRIVACY button again. It should turn
green within a few seconds.
If users are accessing the camera when privacy mode is turned on, the
camera image area displayed in their web browsers turns gray. No camera
pages can be accessed by users while privacy mode is turned on. Once
privacy mode is turned off, users can press the refresh button in their web
browsers to view images again.
The camera’s administrator can also turn privacy mode on and off using a
PC or a mobile phone, and the PRIVACY button itself can be disabled so
that privacy mode cannot be turned on or off by pressing the PRIVACY
button.
For more information about privacy mode, see 7.5 Privacy Mode in the
Operating Instructions on the CD-ROM.
Note
• If you plan on using the PRIVACY button to turn privacy mode on
and off, make sure you mount the camera where you can reach the
button.

Other Notes

• Camera images can be viewed in relatively dark areas, however, image
quality decreases when viewing dark images. We recommend using
supplemental lighting for best results.
• Prolonged exposure to direct sunlight or halogen light may damage the
camera’s optical sensor. Mount the camera appropriately.
Wall Mounting the Camera
Caution
• Do not drive the screws into a soft material. Drive the screws into a
secure area of the wall, such as a column, otherwise the camera
may fall and be damaged.
• Make sure you attach the safety wire when mounting the camera, to
prevent the camera from falling.
Note
• Use screws that are appropriate for the material of the wall.
• The included screws are for use with wooden walls only.
• The camera is intended for indoor use only and should not be
mounted outdoors.
• To ensure that camera images are displayed properly, do not mount
the camera on an incline. Mount the camera so that it is
perpendicular to the floor. Do not mount the camera upside down.
1. Using the template on the right as a guide, drive screws A (included)
into the wall.
• Pass each screw A through washer S (included).
• When driving the screws into the wall, be careful to avoid touching
any metalwork (metal/wire laths etc.), conduits, or electrical cables
behind the wall.
2. Attach the safety wire to the tripod mounting hole on the bottom of the
camera using the safety wire screw (included).
3. Mount the camera on the screws by inserting the screws into the
camera’s wall mounting holes, then sliding the camera down until it is
secure.
• Leave 1.8 mm (1/16 inch) of space between the screw heads and
the washers, as shown below.
4. Secure the safety wire to the wall using screw B (included) and washer
L (included).
• Leave some slack in the safety wire, as shown.
