Still not secure - email I got from Foscam - dated June 12 2017
The vulnerabilities affect "Foscam" branded cameras and cameras manufactured by China-based Shenzhen Foscam only. The vulnerabilities DO NOT affect Amcrest or FDT branded cameras which are produced by a separate factory and R&D team led by US-based Amcrest (formerly Foscam US and now Amcrest), which is totally unrelated to China-based Shenzhen Foscam. 

Amcrest split off from China-based Shenzhen Foscam in 2015 / 2016 due to issues relating to distribution, lack of security and quality control and thus Amcrest and FDT cameras are totally unaffected by these latest security vulnerabilities.

We recommend disconnecting your current Foscam branded cameras from the internet until these issues have been resolved. If you have any questions, please reach out to China-based Shenzhen Foscam directly.
