One hand on the phone
Lesbian POV is filmed by one of the two women in bed, so the gear is whatever she can hold or wear: a phone in one hand, a small action camera on a head strap, a mount clipped to the chest. Her partner talks to the lens, looks into it and reaches for it, because the lens stands in for the face of the woman holding it.
What the free hand does
Holding a phone costs a hand, and the free one does the work: two fingers in her pussy, a grip on a hip, a thumb rubbing the clit. Oral recorded from above puts the partner's face between the thighs with her eyes turned up to the lens. A head strap gives both hands back, and a mount at the hips is the standard rig for harness sex, so whoever wears it can fuck from behind and record each thrust without anyone else in the room.
Toys within arm's reach
Toys suit the format because they can be handed across without breaking the view, and dildo play lets the woman in front of the camera show the shaft to the lens and guide it in herself. There is no outside observer in lesbian POV: whoever holds the lens is also in the sex.
