why script doesnt change the camera position?

i'm trying to make a script that spawns a vehicle and then positions the camera on it but it isnt working, i think its because i'm using a server script.

game.ReplicatedStorage.Eventos.Defender.OnServerEvent:Connect(function(plr)
local defender = game.ServerStorage.Defender
    local oi = defender:clone()
    local cam = oi.camera
    oi.Parent = game.Workspace
    Camera.CameraSubject = cam
    Camera.CameraType = "Scriptable"

end)

i'm using a server script because i'm new on the area and dont know how im going to make the script change the camera on the correct model
