Still no firmware upgrade here?  My 6010L experiences recently frequent disconnection, compared to other older D-Link cameras maybe due  to wear and tear of upgrading/downgrading version.  The tint is still there.

The following are the listed fixes included in F/W v1.12.02: 
1. Fixed the 2-way audio failed issue on iOS8
2. Fixed the issue of faulty auto-firmware upgrade mechanism
3. Fine-tune the wireless performance
4. Fixed the issue found no video streaming when the device was boot in low
light environment.
#3 or even #4 look like something that may help with the issue you are seeing.  Give it a try and if you care... feedback the community.  Thanks
