Workplace voyerism

I work for Sears in Lawrenceville NJ and I need advice. The Sears store that I work have an unwritten policy of only hiring White males to work in Loss Prevention where they single out Black employees and shoppers. My problem is that I work in the receiving department which is wired for sound and Loss Prevention have been using the surveillance equipment

to make derogatory comments about me then they zoom the camera in on my face to see my reaction to the insult they also also allow unauthorized people ususlly female co-workers to sit in front of the monitors and encourage them to make comments over the intercom system where they all laugh. Every time I come in to work my co-workers and managers laugh and snicker when I pass by and it's really starting to make me angry to the point of violence. What are my options here?
