Wireless Communication Function Notes
If the transmission rate drops, the connection is lost, or other problems
occur when using the wireless communication functions, try the following
corrective actions.
Distance Between the Camera and the Smartphone
If the camera is too far from the smartphone, a Wi-Fi connection may not
be established even when Bluetooth connection is possible. In this case,
bring the camera and the smartphone closer together, then establish a Wi-
Fi connection.
Installation Location of Access Point Antenna
z
When using indoors, install the device in the room where you are using
the camera.
z
Install the device where people or objects do not come between the
device and the camera.
Nearby Electronic Devices
If the Wi-Fi transmission rate drops because of the influence of the following
electronic devices, stop using them or move further away from the devices
to transmit communication.
z
The camera communicates over Wi-Fi via IEEE 802.11b/g/n using radio
waves in the 2.4 GHz band. For this reason, the Wi-Fi transmission
rate will drop if there are Bluetooth devices, microwave ovens, cordless
telephones, microphones, smartphones, other cameras, or similar
devices operating on the same frequency band nearby.
Cautions for Using Multiple Cameras
z
When connecting multiple cameras to one access point via Wi-Fi, make
sure the cameras’ IP addresses are different.
z
When multiple cameras are connected to one access point via Wi-Fi, the
transmission rate drops.
z
When there are multiple IEEE 802.11b/g/n (2.4 GHz band) access points,
leave a gap of five channels between each Wi-Fi channel to reduce radio
wave interference. For example, use channels 1, 6, and 11, channels 2
and 7, or channels 3 and 8.
