More and more homes are using surveillance cameras these days. Surveillance or monitoring cameras are also called closed-circuit television (CCTV) equipment or systems. As a security device, the presence of a CCTV can deter burglary and other crime because it poses risks of apprehension and penalty. In cases when it is hidden, it can facilitate the identification of suspects or the reconstruction of a criminal incident.

Aside from CCTV, there are other security and personal dense tools that can be kept at home: ~ pepper sprays ~ stun guns ~ Airsoft spring guns ~ hand tasers, and ~ door jams/braces with alarm.
