These sensors are
similar to the motion detectors that turn on outdoor floodlights. That approach can cut costs, but we don’t recommend it. Motion sensors cause the majority of false alarms. Worse, they detect burglars only after they’ve entered your home. That can create a dangerous situation where you come face to face with a burglar in your hallway. Door and window
transmitters are the only way to detect break ins immediately.

"Security camera registration and monitoring is a community based crime prevention opportunity and investigative tool that enlists the help of residents and can help prevent crime on three levels. Residential video surveillance cameras can deter criminals from entering the area, can prevent crimes from occurring and help solve crimes by providing valuable evidence to the police. "Material collected by surveillance cameras has been used as a tool in post event forensics to identify tactics, techniques and perpetrators of terrorist attacks. It has been argued that terrorists won't be deterred by cameras, that terror attacks aren't really the subject of the current use of video surveillance and that terrorists might even see it as an extra channel for propaganda and publication of their acts. In Germany calls for extended video surveillance by the country's main political parties, SPD, CDU and CSU have been dismissed as "little more than a placebo for a subjective feeling of security". Proponents of CCTV cameras argue that cameras are effective at deterring and solving crime, and that appropriate regulation and legal restrictions on surveillance of public spaces can provide sufficient protections so that an individual's right to privacy can reasonably be weighed against the benefits of surveillance. However, anti surveillance activists have held that there is a right to privacy in public areas. Furthermore, while it is true that there may be scenarios wherein a person's right to public privacy can be both reasonably and justifiably compromised, some scholars have argued that such situations are so rare as to not sufficiently warrant the frequent
compromising of public privacy rights that occurs in regions with widespread CCTV surveillance. For example, in her book Setting the Watch: Privacy and the Ethics of CCTV Surveillance, Beatrice von Silva Tarouca Larsen argues that CCTV surveillance is ethically permissible
only in "certain restrictively defined situations", such as when a specific location has a "comprehensively documented and significant criminal threat". A 2007 report by the UK Information Commissioner's Office, highlighted the need for the public to be made more aware of the growing use of surveillance and the potential impact on civil liberties. In the same year, a campaign group claimed the majority of CCTV cameras in the UK are operated illegally or are in breach of privacy guidelines.

The waterproof button assembly is formed in the opening on the front cover plate of the device housing. The waterproof button assembly further includes a button top, a
flexible gasket, a button structure, a plurality of LEDs, and a light guide component. The flexible gasket is mounted below the button top. The button structure, the LEDs and the light guide component are mounted below the flexible gasket. The flexible gasket is configured to deflect in response to a press on the button top of the button assembly. The flexible gasket has a top surface impermeable to water and edges that extend beyond sides of the button top. The edges of the flexible gasket include a first peripheral edge and a peripheral region located in proximity to the first peripheral edge. The first peripheral edge of the flexible gasket makes a water tight seal with a second edge of the opening of the front cover plate, and the peripheral region of the flexible gasket is
substantially transparent to visible light. The button structure is configured to be actuated in response to the press on the button top. The LEDs is disposed in proximity to the button structure. The light guide component is further disposed in proximity to the LEDS.
