burglar alarm systems

fake security cameras

So protecting all doors is a must. Example: magnetic circuit breakers. Door contacts may be hardwired or wireless; hardwired contacts are usually buried in the doorframe, which is less obvious than wireless and are preferable. Window Contacts: Can be hardwired or wireless. Motion Sensors: It’s the most essential and common form of protection. Passive infrared sensors: Detect motion by sensing a sudden change in heat. Dual Tech motion detectors use two different technologies in the same unit: passive infrared and microwave. These devices are designed to avoid false alarms since both technologies must detect motion before setting off the alarm. Photoelectric Sensors: These sensors project a beam of light across a hall or doorway to detect motion and are triggered when a person passing through interrupts the beam. Glass Break Detectors: Usually mounted near windows to detect the specific high frequency sound of glass being shattered. They are usually installed on a wall opposite or adjacent to the protected glass and are effective within about 15′ to 25′.

As home automation becomes a bigger part of many people’s lives, home security providers are updating their equipment to fulfill the demand. The Nest Secure and Vivint’s Smart Hub, for example, not only function as the brains of your security system, but also as hubs for home automation. Most home security companies also offer smart devices — like locks, garage doors, and doorbell cameras — that pair with their systems and can be managed through their apps. And if your security system doesn’t operate as a smart hub, you may sync with third party smart hubs that let you manage both security and non security related devices on a single platform. Many surveillance cameras and audio bugs emit radio waves and can be identified by a standard RF radio frequency detection device. Conduct a “sweep” of your home with your bug detector.
