He also admitted three counts of possession of indecent images of children (Categories A, B and C), two counts of distributing indecent images of children and two counts of sexual abuse of a dog.
Truro Crown Court heard Tyler's vile abuse only came to an end when the National Crime Agency were alerted to indecent images being uploaded to the internet.
Officers also discovered indecent images and videos of child sex abuse - including some with newborn babies.
But Judge Carr branded the abuse "horrific" and said Tyler posed a risk to both other people and animals.
The fiend's electronic devices were seized by police - including a computer and mobile phone containing the child sex abuse images.
