You can try

TogglePlayerSpectating or PlayerSpectatePlayer but I'm not sure if this will work

Like this

pawn Код:

if(strcmp("/cam3", cmdtext, false) == 0)
    {
        TogglePlayerSpectating(playerid, 1);
        return 1;
    }

or

pawn Код:

if(strcmp("/cam3", cmdtext, false) == 0)
    {
       TogglePlayerSpectating(playerid,1); 
           PlayerSpectatePlayer(playerid,playerid);
        return 1;
    }
