C4 and motion sensor rework

A lot of people use C4 for throwing, making it extremely overpowered due to its damage and explosion radius, I think C4, upon being thrown, should have much less damage and explosion radius for about 4 seconds before it can be detonated. It will also make a beeping sound similar to breachers but each beep is further apart from each other

This could work along with the motion sensors rework, which if there is a motion sensor near a site then a pop-up will appear above a site that says enemies nearby instead of making a little beep that nobody pays attention to, this can be used in co ordination with the C4 to be detonated whenever a player sees the notification. The motion sensor will also have a different model to look like a motion sensor in real life, which can only sense motion in a straight line, this line is also indicated by a red beam (similar to breachers tripmines), 2 can be deployed at a time.
