video recorder

Just a thought came to my mind
What if swara has kept a video recorder in rags room, because she last visited was ragini n lakshs bedroom, where she saw two bottles of water. While coming out she might hv kept a recorder exactly like rags did to her.

N she going in all bedrooms was just to confuse rags so that rags dont hv any suspicion on her going to her bedroom only.
Only ragini can confess her crime so wen she will speak to dadi then all her confessions will be recorded.

Swara earlier said that footprints which she saw dont cross a certain area of the house, then why will she search the whole house.
I guess to confuse ragini.

Just my pov.
