Because of this, entry‑level NVRs have a limited decoding capacity—typically up to 4 channels at 1080P or 1 channel at 8MP.
On a small 4‑channel system, this limitation is usually not an issue. However, using the same decoding capacity (4 × 1080P) on a 16‑channel NVR can create problems.
Normally, when viewing all 16 cameras at once, the NVR displays the sub‑streams, and a decoding capacity of 4 × 1080P is sufficient for a 4K monitor (which is essentially 4 × 1080P). But the relationship between monitor layout and sub‑stream resolution becomes important when the number of cameras increases.
For example, an Easy‑P camera uses a 720P sub‑stream, which equals:
4320 (vertical resol. of a 4K screen) ÷ 720 = 6
This means that when the monitor displays more than 6 cameras using the default 720P sub‑stream, the NVR may not have enough decoding power to handle them all simultaneously.
So, what can you do if you are using a Safire Smart SF‑NVR3116‑B1?
If you don’t do this, the NVR may automatically change the sub‑stream settings back to its defaults.
Adding the camera to the NVR
- On the NVR, choose Add Manually.
- Select ONVIF as the protocol.
- Enter the camera’s IP address, along with the username and password of the user you just created on the Easy‑P camera.
