Police said the cameras have been installed in 20 sensitive places of the district to secure the pilgrimage route.
The yatra which started from July 15, will be concluded on August 1.
Every year pilgrims (known as Kanwarias) start carrying water from Ganga in Haridwar and offer it to lord Shiva on August 1.
These devotees carry holy water in small pitchers back to their homes, traveling all the way on foot.
