hi3518 M709 Cam - How to get the 1080p stream url?

[ben234532141]

Hey folks,

I've been documenting the M709 Mini Cam which is based on the hi3518 chipset.

I've discovered almost everything I need about this camera which is documented on the Domoticz Home Automation forum here:

M709 1080p Mini Camera with WiFi (extremely small) - Domoticz

What I can't figure out though is how to get the 1080p stream via H264, I can get it via MJPEG at about 3 frames per second but obviously that isn't ideal.

When using either the Internet Explorer Active X plugin or the HDMiniCam Android app I can select 1080p and the quality does increase compared to when 720p is seleted.

I've tried both wireshark and charles proxy trying to understand how the 1080p resolution is accessed but can't make sense of it.

Accessing the H264 stream via:
http://192.168.0.127/videostream.asf?user=username&pwd=password&resolution=64

Gives me the 720p stream, 8,32 and 64 are resolutions that I've got to work in the URL, 128 does not give me 1080p.

I'm really trying hard to understand how the IE plugin and Android apps are accessing the 1080p stream.

If anyone has any idea's I'd be very grateful.

This is a completely stupid guess, but have you tried "&resolution=96" by any chance?
Otherwise, it could be a different URL entirely for the highest resolution stream.

Unfortunately yes, I've guessed just about every combination, eg 56, 164, 256, 512, 1024, 2048, 4192
