Hi there,
I have written a detailed blog post on the precautions one needs to take while pursuing a Ph.D. through off-campus and distance modes. Please visit the following link: Human Resources, Business, Management, and Career Questions Blog: How to identify fake, real, recognized, and not recognized M.Phil and Ph.D. degrees in India.
Secondly, IGNOU offers a Ph.D. in distance mode. Please read the following link for details: Simply Govind: Universities offering distance learning courses in India- Delhi.
Apart from that, if you visit my various blog posts on both the blogs mentioned above, you will find a state-wise list of approved universities offering distance education, courses, territorial jurisdiction, etc.
