Hello @sumitalahri and welcome to the Community! I found this document online that describes using a webcam with Respondus Lockdown Browser, Using LockDown Browser with a Webcam: The Student Experience | Respondus News. In the documentation under step 4 the guide states:
- If your exam requires the use of a webcam (sometimes referred to as Respondus Monitor), you’ll be guided through a brief set of screens prior to the start of the exam.
- The first screen is a webcam check, where you can make sure the webcam is working properly. Additional steps may be required by your instructor, such as showing your identification, or recording a brief video of your examination setting.
Does this match what you are seeing or does it help answer your question?
Best wishes!
