As the Daleks deploy to make their assault on the cave, a large TV camera labeled #5 is visible in the background.
At the end, even though the Doctor and Vicki are supposed to be there alone, a shadow can be seen moving on the top right of the Time-Space Visualizer.
As the Doctor, Ian, and Barbara move through the jungle, the camera tilts upwards, revealing the top of the backcloth and the studio lights above.
When Vicki stops in the jungle to face the fungoid, a boom microphone and the hand of its operator can be seen in the jungle behind her.
The Daleks clone of the doctor is less than successful as in many shots it's not William Hartnell; it's a double Edmond Warwick.
