Both operate as some kind of Punisher or hitman and stuff.
Also, I thought of this because maybe, Warwick becomes or causes too much of a problem for the nobles including her clan in Piltover and Camille would have to intervene.
So what would happen if they were to clash?
It stings a little to admit it, but I think think Camille would clearly win. Let's be real, Warwick isn't the smartest, neither is he extraordinary skilled in combat, at least not since his transition. All he has going for him are his animalistic abilities. While he is able to do some basic planning to lure out certain targets as seen in his color story, once actual combat begins he is completely driven by instinct. While for most people facing an enraged wolf-bat-fox-and-whatever-else-Singed-put-in-him chimera is certain death, I believe Camille will be able to handle the situation with relative ease, given her superior weaponry, calm and calculated demeanor, and combat experience. And that's completely neglecting the fact that Camille is the aggressor in your scenario. She'd have all the time in the world to plan ahead or gather intel in order to craft the perfect trap or weapon against Warwick, should she deem those means necessary.
pretty sure camille doesn't care but given what she's capable of she'd probably beat warwick
considering Camille is like a secret police force or something and warwick is like a well murderous vigilante
although tbh still don't think she'd care she did let 
blow up piltover after all so she probably has different priorities than warwick, especially since they both seem to be after chembarons
Hell they might even end up teaming up or something, that'd be cool
question yourself: what are both capable of doing?
Camille prefers ambushing and precision strikes with her blade legs which can cut trough cyborg body parts, while using her shield to absorb incoming attacks, the fights she pick are very short.
Warwick is seen tearing trough entire gang of cyborg/mutants and steel walls on a regular basis, any blood spilled also sends him into a rampage and he relentlessly hunts down his prey.
next up: where does their combat prowess come from?
Camille: form 60+ years of experience and her cyborg body is sustained by a hextech crystal.
Warwick: animalistic instinct, fragmented human memories, questionable chemicals which are constantly alchemised by the chamber on his back and a whole lot of rage.
soo all-in-all i cant really answer this one, Camille would never pick a straight up fight unless she has no other choice, whilst warwick follows the mantra of 'rip and tear until its done'
That's all
It probably wouldn't be a 1v1 though, unless Camille is the last one standing after ww has a few bites with her fodder squads.
After the clash Camille will have a new rug. She will not fight WW unless she plans the fight good enough to be sure to win. If she fails, she can escape. WW is hard to escape from, but Camille can probably outrun him with her devices On the other hand WW isn't going to escape if fight goes bad for him. However, if WW is the one ambushing her on her mission in Zaun, he has a chance to win this.
Camille. It's not even a contest.
A better opponent would be Urgot Imo.
Warwick would win. (Im voting for him because he is one of my favorite champs). Teeth, claws and undying fury. Warwick is a monster. Camille is a scissor-legged lady. Warwick stomps her easy.
