5.7 Camera Recorder Module
Check point
Check each network environment.
• Is PoE power supplied when using a PoE network
camera?
• Is the power of a hub turned ON?
• Is there any disconnection in the connection
route?
Are the IP address, subnet mask, and default
gateway set for the network camera?
(Check the IP address set for the network camera by
using a dedicated tool for the camera.)
Does the IP address (first octet to third octet) set for
the network camera match that of a camera recorder
module?
(Check the IP address set for the network camera by
using a dedicated tool for the camera.)
Is the default gateway set for the network camera
correct?
Is the IP address duplicated in the system?
Are 33 or more network cameras connected on the
same network to which a camera recorder module is
connected?
Check each network environment.
• Is PoE power supplied when using a PoE network
camera?
• Is the power of a hub turned ON?
• Is there any disconnection in the connection
route?
Is a user created for a network camera?
Does each item (IP address/user ID/password/TCP
port number) set in the communication test screen in
the module extended parameter match a
corresponding setting value of a network camera?
(For the method for checking setting values of a
network camera, refer to the manual for the network
camera used.)
(Page 108 Communication test screen)
Are the following values set in the network camera
setting?
• Video codec: Value other than H.264
• Communication with a camera recorder module:
Value other than HTTP protocol
Corrective action
Take any of the following corrective actions according to the
check result.
• Supply PoE power to the network camera.
• Turn the power of the hub ON.
• Connect the cables properly, or replace them with new ones.
Set the IP address, subnet mask, and default gateway of the
network camera according to those of a camera recorder
module by using a dedicated tool for the camera.
For details, refer to the manual for the network camera used.
Set the IP address of the network camera according to that of
the camera recorder module by using a dedicated tool for the
camera.
For details, refer to the manual for the network camera used.
Check if the network configuration is correct.
If another LAN segment is relayed via a gateway, contact the
network administrator of the connected LAN.
Review the setting to avoid IP address duplication in the
system.
Perform either of the following operations to reduce the
number of connected network cameras to 32 or less for
search.
• Power OFF a network camera that is not a target for search.
• Disconnect the cable to a network camera that is not a target
for search.
Take any of the following corrective actions according to the
check result.
• Supply PoE power to the network camera.
• Turn the power of the hub ON.
• Connect the cables properly, or replace them with new ones.
Create a user by using a dedicated tool for the network
camera.
For some network cameras, create another account for ONVIF
communication.
For details, refer to the manual for the network camera.
Enter each setting value of the network camera (IP address/
user ID/password/TCP port number).
Change the values to the following ones:
• Video codec: H.264
• Communication with a camera recorder module: HTTP
protocol
