Q4. What should I do if I remove a camera from the NVR system ?
The steps to add it again are the same as adding a new camera. Find the camera
•
that matches with the deleted channel, connect it to the NVR with the Ethernet
cable, then go to Video Manage > Auto Add to add it.
Q5. How long is the storage time of the Hard Disk Drive ?
The example below is for an average data rate 1024Kbps and 4 cameras. Storing
•
the videos for one day takes up about 42.19GB storage based on formula below:
1024 (Kbps) * 3600 (seconds per hour) * 24 (hours per day) * 4 (Channels) =
353,894,400Kbit
353,894,400Kbit= 44,236,800KB
44,236,800KB=43,200MB
43,200MB= 42.19GB
If you have a 1TB Hard Disk Drive, the capacity of it after formatting is around
921GB.
The storage time is around 22 days (921GB/42.19
However, the data rate of the camera is Variable Bitrate which depends on the
surveillance environment. If there are many moving objects in the live picture, the data
rate will be higher. Go to System setup > Channel setup to check it, then use the formula
mentioned above to calculate it.
Q6. NVR system cannot detect the Hard Disk Drive.
Make sure the NVR works well.
•
Make sure the power cable and SATA cable of the Hard Disk Drive are connected
•
correctly and firmly.

•
