Through surveillance cameras, the police can both prevent crimes from happening and can quickly solve criminal cases with material evidence. In addition, surveillance cameras protect against property theft, and vandalism.
Security intercom systems are used to provide voice communications between two or more locations for security purposes.
All businesses, whether small, medium or large, have assets that need to be protected from theft. There is also the issue of protecting staff and their property. It is common in buildings that are secured by locks and keys for doors to be left unlocked all day.
In addition, a key benefit of audio monitoring is that it helps to combat false alarms and provides a secondary verification in the case of an emergency, robbery, security threat or other intrusion by allowing companies to both see and hear what is going on (when combined with video security technology).
