Optimizing IP camera configuration

This manual shows you how to set up your IP camera. The model screenshots were taken from the IPCAM PTZ camera model C6F0SgZ3N0P6L2, however, the same settings can be applied to most brands. Cameras that will have very similar settings are Clearview, Dahua, Hikvision, Gise and Qsee.

Format Video

To avoid the flickering effect that is associated with the current frequency, set it to 50 Hz.

Encoding mode

Always select the highest compression level in the following order: H.265, H.264H, H.264, and MJPEG.The only reason for lowering the compression level is a compatibility issue.For example, some viewing programs may not be able to display recorded H.265 content (VLC player can handle it perfectly at the appropriate settings), in which case you may need to set the default H.264.

Resolution

Always choose the highest resolution available, typically 1080P (1920 x 1080).

In general, IP cameras should be set to the highest available resolution.However, if you can lower the resolution without noticeable loss of quality (see also how the image looks at magnification), there's no reason not to lower it.

For a substream, you may need to adjust the resolution to match the preferred aspect ratio of the specified playback device.Most of them use a 4:3 aspect ratio (16:11).

Frame rate

My default IP camera frame rate is typically 12-15 fps in the main stream and 10-12 fps in the secondary stream.

There is almost no reason to use the highest frame rate available.Consider the purpose of your IP cameras and decide whether it's cinema-quality and whether cinema quality is worth the bandwidth and memory consumption that comes with it.

Setting frames per second affects the smoothness of motion recording.If your IP camera is above the cash register, you may need to increase the frame rate to catch your fast-moving hands.However, if your IP camera is in a low-traffic room, a higher frame rate is not necessary and it is better to save bandwidth and memory.

I believe that the frame rate of 15 frames per second is smooth enough to capture fast-moving hands, and a frame rate of 10 frames per second is sufficient in low-traffic areas.

If the video is too uneven, increase the frame rate by 10% until smooth.Remember, however, that this is not cinema.

baud

The bit rate should typically be 40% of the maximum value provided by the engine.

The appropriate setting of the baud rate is direct control over the transfer consumption of the IP camera. Therefore, the baud rate should be set to the lowest possible level without adversely affecting the image.

If the IP camera does not have suggested options, then for 2 MP with H.265 at 15 FPS start at 2048 Kbps.Reduce to 1024 Kbps to see if there is a difference.Double these values for a 4 MP IP camera and add 50% if you are using H.264.

Transmission control

For cameras with a slow processor, set the fixed bit rate mode – CBR. In any other dynamic mode – VBR. This is due to the fact that with a dynamically changing scene in VBR mode, the free processor will not be able to increase the bit rate to capture all the details. However, VBR mode saves a lot of space and transfer, especially in static scenes.

Additional remarks – P2P protocol

Due to security holes related to the implementation of P2P in IP cameras, I recommend disabling this protocol.
