Wireless Communication Function Precautions
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
When using indoors, install the device in the room where you are using the camera.
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.
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.
Precautions for using multiple cameras
When connecting multiple cameras to one access point via Wi-Fi, make sure the
cameras' IP addresses are different.
When multiple cameras are connected to one access point via Wi-Fi, the transmission
rate drops.
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.
Using wireless remote control BR-E1
BR-E1 cannot be used while the camera and smartphone are paired via Bluetooth.
Change the camera connection to the wireless remote control in [
Connect to Wireless
Remote ] under [ : Wi-Fi/Bluetooth connection ].
