Security Cameras is one you are looking for

There is a wide range of spy cameras available there on the market. The common factor of distinction between them is about their ability to record pictures or videos. There are spy cameras with or without sound recording abilities obtainable as well. Distinction is also made on the basis of size and on how they are camouflaged. For instance, there are spy cameras designed in pens, acknowledged as spy pen cameras, or within clocks, electronic devices and even children’s toys. Spy cameras can be wired, wireless or even keep record of data on them spy cameras For example a user’s access rights could allow access from 0700h to 1900h Monday through Friday and expires in 90 days. Another form of access control (procedural) includes the use of policies, processes and procedures to manage the ingress into the restricted area. An example of this is the deployment of security personnel conducting checks for authorized entry at predetermined points of entry. This form of access control is usually supplemented by the earlier forms of access control (i.e. mechanical and electronic access control), or simple devices such as physical passes. wired cameras An additional sub-layer of mechanical/electronic access control protection is reached by integrating a key management system to manage the possession and usage of mechanical keys to locks or property within a building or campus.The third layer is intrusion detection systems or alarms. Intrusion detection monitors for unauthorized access. It is less a preventative measure and more of a response trigger, although some[who?] would argue that it is a deterrent. Intrusion detection has a high incidence of false alarms. In many jurisdictions, law enforcement will not respond to alarms from intrusion detection systems.[citation needed] For example, a motion sensor near a door could trigger on either a person or a squirrel. The sensor itself does not do identification and as far as it is designed, anything moving near that door is unauthorized. security cameras

CCTV recording systems are still often used at modern launch sites to record the flight of the rockets, in order to find the possible causes of malfunctions,[6][7] while larger rockets are often fitted with CCTV allowing pictures of stage separation to be transmitted back to earth by radio link.
