This is possibly a better webpage to look at:

In the video, Slater says he set the camera up on a tripod with
a remote (cable?) shutter release for the monkeys to use.

Just below the video, there is a pair of monkey photos. The RH
uncropped one is the one I had in mind in my previous post, with
the monkey's outstretched arm reaching towards the camera. This
looks entirely consistent with the camera being on a tripod and
being operated by the monkey with a cable release.
