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. Surveillance devices are often hidden in walls or ceilings, so look for any spots that appear to be spackled or recently concealed. However, with the decreasing size of surveillance equipment, illegal surveillance can be concealed virtually anywhere. Household objects such as pens, clocks, lamps and even watches may contain devices to see and hear what you are doing. Closely examine your home's windows, as the exterior of windows are excellent places for installing illegal surveillance devices since no one has to break into your home to install them.

The display lets you communicate with a professional monitoring service when an alarm is triggered and view video from any of the installed security cameras. While many systems use wireless components that are installed using double sided tape, some high end systems use components that require professional installation. These soup to nuts systems typically cost considerably more than DIY systems and offer 24/7 professional monitoring, but you may have to enter into a multi year contract and pay a hefty termination fee if you break it. They usually use touch screen hubs thatcontain RF, Wi Fi, Zigbee, and Z Wave radios, allowing them to communicate with and control a multitude of components including door and window sensors, door locks, glass break detectors, indoor and outdoor cameras, light switches, motion and water detectors, smoke/CO alarms, thermostats, video doorbells, and a host of other home automation devices. With a professionally monitored system, when a smoke or intrusion alarm is triggered, an agent will first try to reach you via the two way control panel before calling your listed phone number. If you fail to respond, the agent will call 911 to dispatch an emergency responder to your home. The nice thing about professionally installed systems is you don't have to lift a finger; after you've placed your order a technician will come to your home, set everything up for you, and show you how the system works. It's important to note that in some areas you may have to file for a permit to have a security system installed in your home. Nearly all of the latest DIY and high end home security systems offer support for voice control via Amazon Alexa, Google Assistant, and in some cases Apple Siri, which allows you to unlock doors, change thermostat settings, open the garage, and arm or disarm your system with a spoken command to a connected device like an Amazon Echo or a Google Home speaker. Many also offer support for IFTTT If This Then That applets, which use triggers from IFTTT compatible web services and devices to create an action. For example, you can create an applet that says if a garage door is opened to turn on the floodlight.
