Appendix A - Troubleshooting and
frequently asked questions
How many channels does the HD-IP470 support?
The IP470 only supports 4 cameras connected with SafeZone2D, however the HD-IP470 can record up to
eight cameras and transmit one of those cameras. It is possible to create multiple quad-views allowing
four cameras to be transmitted simultaneously.
What level of recording and streaming performance is
achievable?
Based on the processing power of the HD-IP470, the unit can achieve 25/30 fps of 1080p quality recording
whilst simultaneously streaming one 1080p video stream at close to 10fps (or 720p at 15fps).
What recording functions does the HD-IP470 support?
The HD-IP470 can be set up to record continuously, or to record on an alarm trigger. Recordings can be
set to overwrite old recordings automatically, or to stop on full.
What indicative recording times and streaming rates are
achievable?
The HD-IP470 records the incoming video stream from IP cameras without modification. By default,
cameras are automatically configured by the encoder to 1080p @ 25/30fps at a bitrate of 10 Mbps when
added to an encoder. This will provide approximately 8 days recordings at a very high quality (multiple
cameras will proportionally reduce this duration) on the supplied 1TB drive.
After adding the camera, and by using the camera’s own configuration interface, the user is usually able to
manually configure lower quality setting on their IP cameras to extend the duration of recordings if
necessary. This table provides an indication of the potential increase in duration possible:
Frame rate
IP Camera b/w
1TB SDD
1 fps
1.4 Mbps
64 days
6.25 fps
3 Mbps
32 days
12.5 fps
5 Mbps
16 days
25 fps
7 Mbps
12 days
720p cameras are approximately half of the resolution of 1080p (and standard definition cameras are
approximately ¼ of the resolution of 1080p) and as such will use proportionally less data.
