Along with Cornell, Stone Gossard, Jeff Ament, McCready, and Vedder, Cameron appeared on the 1991 Temple of the Dog album.
The album paid tribute to Mother Love Bone vocalist Andrew Wood, who died of a heroin overdose at age 24.

He has played in two jazz-influenced side projects: Tone Dogs in the early 1990s, and Harrybu McCage, which formed in 2008.
He recorded with the Tone Dogs for their debut album Ankety Low Day, which was released in 1990.
Cameron also has a fondness for psychedelic garage rock, and his side projects Hater and Wellwater Conspiracy reflect this.
Cameron formed Hater in 1993 with Soundgarden bassist Ben Shepherd.
The band released a self-titled album in 1993 and recorded a second album in 1995 following Soundgarden's Superunknown tour.
The band's second album, The 2nd, would not see release until 2005.
Cameron founded Wellwater Conspiracy with Shepherd and guitarist John McBain.
The band's debut album, Declaration of Conformity, was released in 1997.
Following Shepherd's departure from the band in 1998, Cameron took over lead vocal duties for the band.
Cameron and McBain maintained the group after Cameron joined Pearl Jam, and a further three Wellwater Conspiracy albums were released following the band's debut album (Brotherhood of Electric: Operational Directives (1999), The Scroll and Its Combinations (2001), and Wellwater Conspiracy (2003)).

He worked with electronic punk act The Prodigy on their breakthrough album The Fat of the Land, providing beats and fills that were sampled for hits such as Firestarter and Breathe.

Cameron appears on the Gamma Ray 7", which would become the first recorded material by Queens of the Stone Age.
Cameron played drums at the band's first show on November 20, 1997 at the OK Hotel in Seattle, however he did not join the band as its drummer.
He also appeared with them in 2008, at the memorial concert for Natasha Shneider, playing double drums along with their then-current drummer Joey Castillo, of which various Queens of the Stone Age and Desert Sessions songs, as well as covers by artist including The Doors and Cream were played.

Cameron contributed his drumming on seven tracks considered for The Smashing Pumpkins' 1998 album, Adore, though only "For Martha" appeared on the album.
Another studio track, "Because You Are", surfaced on the 2001 B-sides and rarities collection, Judas O. Rumors circulated in the beginning of 1998 that he was considered as a permanent drummer replacement for Jimmy Chamberlin, but Cameron denied this.

Other drumming contributions by Cameron include four tracks on Eleven's 1995 album, Thunk, the track "Disappearing One" on former bandmate Chris Cornell's 1999 solo album, Euphoria Morning, and Geddy Lee's 2000 solo album, My Favourite Headache.

Cameron has enjoyed a friendship with fellow drummer Jeremy Taggart of Canadian rock group Our Lady Peace.
When Taggart was sidelined with an ankle injury during the recording of that group's 2000 album, Spiritual Machines, Cameron played drums on songs such as "Right Behind You (Mafia)" and "Are You Sad?".
Cameron contributed to the soundtrack for the 2002 film, Spider-Man, playing on "Hero" with Chad Kroeger and Josey Scott.
As Cameron was unable to attend the shoot, Jeremy Taggart returned the favor and is shown in Cameron's place in the video.

Cameron, along with Pearl Jam bandmate Mike McCready, contributed two songs to Peter Frampton's instrumental album, Fingerprints (2006).
These include a cover of Soundgarden's "Black Hole Sun" and "Blowin' Smoke".

Cameron has lent his talents to Submersible Music's DrumCore software.

In 2013, Cameron performed with drummers Janet Weiss of Sleater Kinney, and Zach Hill of Death Grips on an all-drum album entitled Drumgasm.
