hi all, this is bill and i am a sales manager in charge of a CLD(camera lowering device) from China. I am here cause I was told it's a professional BBS for CCTV and I am looking for your opinions for a rough but workable design of our products. As a 11 years factory, we are focus on being a reliable supplier which we are aware it will be a long distance from now but we will carry on. thanks for your time reading this and longing for your suggestions, bill
