Effective Security

My company is seeking an experienced freelancer to help us with our security needs. We are looking for someone who can implement effective security measures across our entire plant & mines , so that we can remain protected from threats. Specifically, we are interested in building access control,cctv monitering and intrusion detection systems. We already have some security measures in place, but we would like for them to be strengthened to provide intermediate security. With these measures in place, we can rest assured that our environment is safe from potential external as well as internal disturbances, stoppage of plant operation and intrusions.
