You could rewrite your code to something like below:

pawn Код:

// Initialize

TogglePlayerSpectating(playerid, true);

CameraMovement[playerid] = 0;

KillTimer(ConnectionCamera[playerid]);
ConnectionCamera[playerid] = SetTimerEx("ConnectionCameraMovement", 1000, true, "i", playerid);

// Function

forward ConnectionCameraMovement(playerid);
public ConnectionCameraMovement(playerid)
{
    switch(CameraMovement[playerid]) 
    { 
        case 0:
        {
            InterpolateCameraPos(playerid, 1977.940917, -1753.394165, 15.710048, 1683.647583, -1725.149780, 15.520676, 13000);
            InterpolateCameraLookAt(playerid, 1972.946899, -1753.489624, 15.485646, 1688.493530, -1726.381225, 15.500365, 2000);

            CameraMovement[playerid] ++;
        }
        case 1:
        {
            InterpolateCameraPos(playerid, 905.286132, -1403.625976, 15.154844, 1353.317626, -1404.655395, 15.989136, 10000);
            InterpolateCameraLookAt(playerid, 910.276306, -1403.326171, 15.062310, 1349.223632, -1401.786621, 15.892268, 2000);

            CameraMovement[playerid] ++;
        }
        case 2:
        {
            InterpolateCameraPos(playerid, 1584.561767, -1731.501708, 14.498149, 1334.697753, -1722.911621, 15.104587, 10000);
            InterpolateCameraLookAt(playerid, 1579.567993, -1731.750732, 14.477837, 1338.359619, -1726.315917, 15.058754, 2000);

            CameraMovement[playerid] ++;
        }
        case 3:
        {
            InterpolateCameraPos(playerid, 165.131668, -1885.581787, 1.454522, 636.477600, -1918.955688, 5.688834, 10000);
            InterpolateCameraLookAt(playerid, 170.110122, -1885.167968, 1.663836, 631.661071, -1917.679565, 5.273429, 2000);

            CameraMovement[playerid] ++;
        }
        default:
        {
            InterpolateCameraPos(playerid, 1828.909790, -1602.995971, 13.485791, 1857.642089, -1431.320312, 16.744033, 10000);
            InterpolateCameraLookAt(playerid, 1825.495117, -1599.407348, 14.165193, 1852.764038, -1432.402221, 16.557880, 2000);

            CameraMovement[playerid] = 0;
        }
    }
    return 1;
}

Just remember to kill the timer when you're done with it.

Also, note that interpolate functions aren't fully accurate in terms of working. They do not always move your camera. You could replace its usage for SetPlayerCameraLookAt, using CAMERA_MOVE in the cut parameter, but you'd be sacrificing the control over time.
