請幫我改這篇英文(好簡單的)

Hi,
I have changed your sentence to the following :
This shop has installed video cameras to avoid illegal act. Once a theft happens, we will report to the police and put the case in the court for jurisdiction.

Please change the sentence to a passive voice :

Video cameras have been installed in the shop to avoid illegal act. Once a theft happens, we will report to the police and put the case in the court for jurisdiction.

閉路電視 = CCTV

CCTV in progress
Call the police if any stealing

本店設有閉路電視，如發現偷竊，本店會報警追究．
若不對，請幫我改正，萬分感謝）
