Your home is your castle, and needs to be defended—even if only from the threat of late-night visits from raccoons. Security cameras ensure that you know what’s happening on the home front at all times. HD resolution cameras, with color imaging, plus pan, tilt, and zoom features, will offer you the clearest view of your property from almost every angle. 
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.
We also have Hybrid CCTV / HD camera DVRs that support both traditional CCTV cameras and these new HD cameras. Hybrid DVRs are extremely practical because they allow customers to use their existing analog cameras (standard definition) and add high definition cameras to their system when they are ready. For new users, they may want to go with a 100% high definition system right away. The same DVR is used because every channel supports real time video recording at any resolution (D1, 960H, 720p, and 1080p). Best of all, users can view all of their cameras remotely over the Internet using the best apps available for Mac, Windows, iOS, and Android.

The network's principal directors and other officers are appointed by the State, and so are the top officials at local conventional television stations in mainland China; nearly all of them are restricted to broadcasting within their own province or municipality.

The combination of CCTV and facial recognition has been tried as a form of mass surveillance, but has been ineffective because of the low discriminating power of facial recognition technology and the very high number of false positives generated. This type of system has been proposed to compare faces at airports and seaports with those of suspected terrorists or other undesirable entrants.[citation needed]
