13. MAINTENANCE
Only clean the NVR using a moist cloth; don’t use chemical cleaning agents. Before
cleaning, always disconnect the adaptor.
14. TIPS AND WARNINGS
1. Set functions don’t work! Please keep in mind that most functions must be supported
by the registered camera and should be sent in the correct protocol. If this is not the
case, those functions won’t work. This doesn’t indicate an error of the NVR.
2. Keep in mind that the registered cameras must be connected to the same network as
the NVR, otherwise the connection will be impossible.
3. Loss of image of an IP camera connected via WiFi. To obtain images without inter-
ference a very stable network connection is essential, because the IP camera uses
streaming video. A delay in the data transmission of the video stream will result in the
loss of images.
4. Nowadays the speed of WiFi connections is very high. Nevertheless, keep in mind
that the larger the distance from the access point (router), the lower the speed and
stability. WiFi cameras are usually located far away from the router or even outdoors.
This will affect the speed and stability.
5. When multiple devices are using the WiFi network, the speed and stability decrease.
When using multiple cameras, it might happen that images disappear more frequent-
ly. This can also happen when using a tablet or smartphone.
6. When there are many WiFi networks present in your immediate vicinity, the speed
and stability of your own network will decrease. To minimise failures in your own WiFi
network, choose a WiFi channel for your router that is as free as possible.
