He was a music teacher at King Edward's School in Edgbaston at the time.
Evans is due to be sentenced at Birmingham Crown Court on 20 December.
The defendant pleaded guilty during a hearing earlier, at Birmingham Magistrates' Court.
'Shocked and saddened'
On 23 August, Evans was charged with three offences, which were later increased to:
The charges relate to the secret filming boys at the school using hidden cameras in changing rooms, the indecent assault of boys and the storage of more than 400,000 indecent images of children on a home computer.
A statement from King Edward's School said: "We are deeply shocked and saddened by these charges and, since August, we have been co-operating fully with the police in their enquiries.
"The safety and welfare of our pupils is our primary concern and we have done all that we can to inform and support parents and pupils."
The West Midlands Police investigation was launched after the force received information about indecent images being downloaded.
