Alarmco, Inc. offers a video surveillance system (closed circuit television) that allows you to observe high risk areas and/or sensitive transactions.  Of course all this can be stored on digital media. 

Statistics have verified that shrinkage and internal theft costs nationally have risen close to $510 billion annually.  The best deterrent of potential internal theft is CCTV.  Just the presence of a camera can deter "inaccurate" vendor delivery and the dishonest employee.

Cameras can be mounted for employee safety.  They can prevent "slip and fall" fraud.  They may be located in entries, stairwells, hallways, parking lots and elsewhere to prevent intruders and secure employee safety.  A very effective way to use CCTV is with  access control.
