Guidelines for using high camera count (>32) TVN recorders
B. For RAID configurations
The TVN 22P and TVN
70/71 support different RAID levels
but with high camera numbers
(>32)
, we recommend to use RAID 5 or 6
.only.
Using RAID 5 or 6
will distribute the recording load over the different hard drives.
Use at least three (
RAID 5) or
four
(RAID 6)
hard drives in a recorder
when using RAID 5 or 6.
See the User Manual of the recorder for more information about how to configure HDD
grouping or RAID.
Network configuration
It is essential that a stable network environment is used.
A poor quality network will result in data loss, offline cameras, and will equally impact the
recorder’s performance.
A qualitative network will increase the recording stability and viewing performance of the
recorder.
We recommend the following settings:
Connect two network ports (TVN 22P, TVN 70) or more (TVN 71). Make sure the ports on
the switches are 1 Gigabit ports.
In the
Network
settings of the recorder, choose the working mode
Load Balance
or
Multi-
Address
For TVN 22P and TVN 71
Set the network working mode to Load Balance and connect all the network ports to the
same switch.
Also the ports of the switch need to be configured in load balance mode.
•
For the TVN 70
The TVN 70 does not support load balance mode. For the TVN 70 it is recommended to
use multi address mode and distribute the cameras load over LAN1 and LAN2. Connect the
network cables to separate, isolated switches.
For the connection between cameras and the recorder it is better to spread the cameras over
multiple switches as well.
It is also important to ensure the use of qualitative non-blocking switches, such as those
available within the Interlogix IFS product range.
Event recording triggers
The process of activating event or alarm recording requires intelligence from the recorder.
When triggering a high number of alarm/event recordings simultaneously, the recorder’s
performance can be impacted.
We advise to limit the maximum number of cameras that will be recorded for an event to four.
This will minimize the risk of impacting the recorder’s performance.
