Surveillance

• Surveillance cameras may help to deter crime. The video from the surveillance cameras is often transmitted to a computer or television and is often recorded. Both indoor and outdoor surveillance cameras are available.
  
  

Security

• Security systems have detectors to monitor points of entry into a building such as windows and doors. If an entrance is breached while the alarm is activated, the alarm will sound. Some systems have silent alarms that simply alert authorities but do not have an audible alarm.
  
  

Monitoring

• Surveillance and security systems may be deterrents by themselves, but they are most effective if they are monitored by a security company. If surveillance is monitored, the security company may be able to prevent a crime in progress, and monitored security companies will alert police if the security alarm is sounded.
