As you know, bandwidth consumption on the cameras/encoders are already low (less than 1 Mb/s). In the daytime, the camera needs to discern details we don't see in our low light scene (such as the carpet). However, in low light, with IR Illumination On, we don't see the carpet as being "complex" anymore. Also, we do not need/see a large amount of low light gain with IR on, and with lower gain, there is less noise, and with less noise, bandwidth is reduced.
Hi Derek, thank you for confirming those points. I wasn't sure if the IR lighting would enable the camera to pick up details in the carpet or not so hence my question. I greatly appreciate you spelling out the factors that explain bandwidth at day vs night.
David, are you using the VS8801 encoder? If so, are you using the ONVIF driver to connect as well as the latest Vivotek firmware / Milestone Driver Pack? Since it looks as though the VS8801 should present as one ip, which means, per the Milestone encoder licensing policy, should require only one license per encoder.
Also, a member mentioned something about getting a 'special firmware' enabled for the VS8801, though it was in regards to Exacq, not sure if it applies...
