FAQ
Q1. Why can't I find the HDD (Hard Disk Drive)?
a. Please check the power and SATA data cables of the HDD to make sure they are properly connected.
b. For some NVRs with the 1U or small 1U case, the power of the adapter may be not enough for operating your HDD. Please ensure you are using
the power adaptor supplied along with your specific NVR.
c. Please make sure the HDDs are compatible with the NVR. See Appendix C Compatible Device List for details.
d. The HDD could have gone bad. Confirm with Speco Technologies technical support and follow the instructions to replace the HDD.
Q2. Why are there no images in some or all the camera windows?
a. Please make sure the resolutions of the cameras are supported by your NVR.
b. Please make sure the network cables of the IP cameras and NVR are both connected properly, and the network parameters are set correctly.
c. Please make sure the network and the switch are both up and running normally.
Q3. Do does my screen have no output after booting the NVR normally?
a. Please make sure the screen, HDMI or VGA cables are functioning and properly connected.
b. Please make sure the screen supports the resolution of 1280*1024, 1920*1080 or 3840*2160 (4K*2K). The NVR cannot self-adapt to a screen
of which the resolution is lower than 1280*1024. In that event, the screen will remind you that the resolution is not supported by the NVR or just
not display anything. Please change the screen to 1280*1024, 1920*1080 or 3840*2160 resolution before booting the NVR.
Q4. What do I do if I have forgotten my password?
The admin password can be reset through the "Edit Security Question" function.
a.
Click the "Edit Security Question" button in the login window and then enter the corresponding answer to the selected question in the popup window.

b.
Q5. Why will my NVR not accept the maximum number of IP cameras?
Take a 16 CH NVR as an example. Some 16 CH NVRs support a maximum of 120Mbps bandwidth input (please take the real device standard). Refer
to the picture below. The remaining bandwidth should be larger than the bandwidth of the IP cameras you want to add, or you will fail to add an IP
camera. You should lower the added cameras' bitrate to relieve the bandwidth. It is recommended to add cameras using "Quickly Add" for batch
adding.
Q6. Why is an IP camera connected directly to the PoE port of my NVR not displayed automatically in the camera list?
a. Please check whether a PoE port is occupied by another IP camera that may have been added through the network (including a PoE switch).
⚫ Take a 16 CH NVR with 8 PoE ports as an example. The resource distribution of the 16 CH IP cameras is shown in the picture below.
When you add IP cameras through the network, the IP cameras will occupy ports from CH1, CH2, CH3, CH4... in the sequence they are added; if you
directly connect IP cameras to the PoE ports of the NVR, the IP cameras will occupy ports from CH9 to CH16 according to the number of the PoE port
each IP camera is connecting to.
Let's say 12 IP cameras have been added to the NVR through the network and no IP cameras have been directly connected to a PoE port. The 12 IP
