Camera Ray doesnt if player is on the side of the camera!

So im scripting security camera’s that follow the player if there in view, so i use raycasting and WorldToScreenPoint but if the player is on the side of the camera, the camera isnt able to detect the player.

	local GetThingsInView = function(Delta)
							if Character:FindFirstChild("Camera") then
								for _, v in pairs(workspace:GetDescendants()) do
									if v:IsA("Model") then
										if v:FindFirstChild("Humanoid") then
											local _, visible = workspace.CurrentCamera:WorldToScreenPoint(v.PrimaryPart.Position)
											local Distance = (Camera.CFrame.Position - v.PrimaryPart.Position).Magnitude
											local Parameter = RaycastParams.new()
											Parameter.FilterType = Enum.RaycastFilterType.Whitelist
											Parameter.FilterDescendantsInstances = {v}
											local CastRay = workspace:Raycast(Camera.CFrame.Position, Camera.CFrame.LookVector * 150, Parameter)
											local Camera_Tables = Get_Camera()
											if visible and Distance <= 50 and CastRay then
												Framework_Gui.Full_Frame.CamFrame.Tracker.Text = "CURRENTLY TRACKING : ".."<font color=\"#affed0\">"..string.upper(v.Name).."</font>"
												Framework_Gui.Full_Frame.CamFrame.Distance.Text = "DISTANCE : ".."<font color=\"#affed0\">"..Distance.."</font>"
												Camera.CFrame = CFrame.lookAt(Camera.CFrame.Position, v.PrimaryPart.Position)
											else
												if Camera_Tables then
													Camera.CFrame = Camera_Tables.Position
													Framework_Gui.Full_Frame.CamFrame.Tracker.Text = "CURRENTLY TRACKING : ".."<font color=\"#fe4141\">".."NO ONE".."</font>"
													Framework_Gui.Full_Frame.CamFrame.Distance.Text = "DISTANCE : ".."<font color=\"#fe4141\">".."NIL".."</font>"
												end
											end
										end
									end
								end
							end
						end

You likely need a larger peripheral value then.
