In this guide, we will show the recommend Video Settings to help the performance and efficiency of the camera's.
Step 1. Main Stream
Mainstream is the primary video feed. Mainstream provides the highest video quality and is the stream the DVR / NVR uses when saving footage to the internal hard disk drive (HDD).
Mainstream settings can be adjusted to increase or decrease Recording Resolution, FPS (Frames per Second), and Bitrate. These settings will impact recording file size and available recording time.
Main Stream FPS(Frames Per Second)
| Use | FPS |
| License Plate Capture | 60 or above |
| Banks | At least 30 |
| Most Businesses | 15 or above |
| Residential | 15 or above |
Main Stream Bit Rate
| Megapixel / Resolution | Suggested |
| 12MP | 12288 |
| 4K/8MP (3840x2160) | 8192 |
| 5MP (2560x1920) | 6144 |
| 4MP (2560x1440) | 4096 |
| 3MP (2048x1536) | 4096 |
| 2MP (1920x1080) | 2048 |
| 1MP (1280x720) | 1024 |
Step 2. Sub Stream
Substream will mainly be used when viewing from a mobile device including tablets.
When using substream on your device you may notice a lag in video, or it may not be showing up. If this happens you may need to adjust the Frame Rate, IIframe Rate and the Max Bitrate accordingly.
Please Note
Slow upload speeds can prohibit remote viewing. We recommend 2Mbps per cam upload speed.
Sub Stream Bit Rate
| Megapixel / Resolution | Suggested |
| 640x480 | 512 |
| 640x360 | 512 |
| 320x240 | 256 |
Step 3. Main Stream (Event)
Like the other settings we've recommended in this guide the Main Stream (Event) settings can vary from one scenario to another. In most cases they can be left at default or Nelly's recommended values for the best performance. However, in some cases such as recording Events only or recording a mixture of Continuous and Event you may want the settings slightly higher depending on the scene.
For example: When something moves into the field of view of the camera it needs to use more resources to capture the movement accurately due to any changes in the scene causing more data to be used.
Main Stream (Event) Bitrate
| Megapixel / Resolution | Suggested |
| 12MP | 12288 |
| 4K/8MP (3840x2160) | 8192 |
| 5MP (2560x1920) | 6144 |
| 4MP (2560x1440) | 4096 |
| 3MP (2048x1536) | 4096 |
| 2MP (1920x1080) | 2048 |
| 1MP (1280x720) | 1024 |
