An early mechanical CCTV system was developed in June 1927 by Russian physicist Leon Theremin. [9] Originally requested by CTO (the Soviet Council of Labor and Defense ), the system consisted of a manually-operated scanning-transmitting camera and wireless shortwave transmitter and receiver, with a resolution of a hundred lines.
The CSR must be accompanied by a proof of origin (i.e., proof of identity of the applicant), which is required for security reasons by the certificate authority. The certificate authority may contact the applicant for further information. Typical information required in a CSR (sample column from sample X.509 certificate). Note that there are ...
Similarly to the Certificate Management Protocol (CMP), it can be used for obtaining X.509 digital certificates in a public key infrastructure (PKI). CMS is one of two protocols utilizing the Certificate Request Message Format (CRMF), described in RFC 4211 , with the other protocol being CMP.
The format of these certificates is specified by the X.509 or EMV standard. One particularly common use for certificate authorities is to sign certificates used in HTTPS, the secure browsing protocol for the World Wide Web.

Design rule for Camera File system (DCF) is a JEITA specification (number CP-3461) which defines a file system for digital cameras, including the directory structure, file naming method, character set, file format, and metadata format. It is currently the de facto industry standard for digital still cameras.
These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
