I might have missed this, but what compression did you test this on, H.264 or H.265? I'd be interested to know if H.265 on the same camera would lower the percentage increase. The overall bitrate would most likely be lower. What would intelligent codecs do, Zipstream, Wisestream, H.265+, etc.

Can you describe more the settings of the cameras , like Frame-rate, and image quality settings. In some cases the 4MP produce less bandwidth as a 1080 resolution from the same vendor.

Very interesting that Sony wasn't tested, the VB770 and newer gen low light cameras are the hottest thing in the industry.

Again, Sony's fault for not getting them out there but the newest releases feature much expanded low light capabilities like the VM772R that are a fraction of the cost of the VB770.

would've been nice to have tested it against the others ;)

What type of light meter do you use? Can you add a column in your reports to show 1 or 2 different lux meters used in the actual tests? I trust what you say but it would be nice to see the numbers from a few measurement devices for a baseline. Thanks in advance.

Good info but at that low level useless if you need to see who or what. You need light.

Editors,
Thank you for this informative article.
Can you please clarify the unit of measurement for the day and night bandwidth values?
Are those mbps, Mb/s, or an arbitrary value?
Thank you.
