Wireless Function Notes - Canon EOS 5D Mark IV Instruction Manual

Wireless Function Notes

If the transmission rate drops, the connection is lost, or other problems
occur when using the wireless functions, try the following corrective actions.
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 transmission rate of a wireless LAN 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 wireless LANs via IEEE 802.11b/

g/n using radio waves in the 2.4 GHz band. For this reason, the
wireless LAN transmission rate may drop if there are Bluetooth
devices, microwave ovens, cordless telephones, microphones,
smartphones, other cameras, or similar devices operating on the
same frequency band nearby.
Notes for Using Multiple Cameras
When connecting multiple cameras to one access point, make

sure the cameras' IP addresses are different.
When multiple cameras are connected to one access point, the

transmission rate drops.
When there are multiple IEEE 802.11b/g/n (2.4 GHz band) access

points, leave a gap of four channels between each wireless LAN
channel to reduce radio wave interference. For example, use
channels 1, 6, and 11, channels 2 and 7, or channels 3 and 8.
Using an Eye-Fi Card
When [Wi-Fi/NFC] is set to [Enable], image transfer using an Eye-

Fi card is disabled.
