Many video surveillance DVRs vulnerable to hacking due to hard-coded root passwords

According to an article by CSO, Digital Video Recorders (DVR’s) made by Zhuhai RaySharp Technology and re-branded by Lorex, Swann, Q-See, and many others apparently contain a hard-coded unchangeable password that can allow anyone full access to your internet connected DVR.    If you have an internet connected DVR it is recommended you contact the manufacturer immediately to see if your DVR model contains this vulnerability. If your model is affected you should update the firmware which includes the security patch (if available) and / or remove it from being accessed from the internet.
