The authoritative resource for physical and converged security
Sanyo has launched its new line of time-lapse recorders. The SRT-6000, SRT-7072 and SRT-7168 offer front panel jog/shuttle control, advanced recording and tape protection system and RS485 control using Sanyo-designed security serial protocol (SSP), a communications method for interfacing between various components of a security video system.
According to Toshiyuki Todo, Managing Director of Sanyo SA, "These recorders are the first generation of security products capable of communicating directly with controllers built by another manufacturer who has SSP built into its controllers. This will simplify system design and produce a more efficient system."
For easier access and operation of the tape-search function, the three recorders have a jog/shuttle control on the front panel. The shuttle control allows easy fast forward and reverse tape viewing. The shuttle control also features a lock-down mode for hands-free control. The jog control allows easy forward and reverse individual picture viewing.
The Sanyo SSP protocol built into the recorders uses both existing RS232C, for connection to a computer, and addressable RS485, for connection to network controllers, as communication methods. This protocol allows the control of up to 255 devices for more effective control of time-lapse recorders.
Advanced recording and tape protection system
The recorders offer a Sanyo-exclusive advanced recording and tape protection system. One component of this system is the tape retry and threading check system. In the event the tape transport is stopped and the tape is returned to the cassette, the recording will automatically re-try to load the tape and return to the record mode. If no other problems are sensed, the unit will continue in normal recording mode. This automatically returns an unattended security system to its fully functional state. The threading check system senses if proper contact is not maintained with the audio and CTL head, and puts the recorder in stop mode if a problem exists.
The recorders also offer an exclusive tape jam-protection system for cylinder tape-jam problems. If there is a problem of loose tape during threading, the supply reel will take up the slack so the tape will load properly. If a problem exists during unloading, the take-up reel will rotate, taking up the excess tape.
The SRT-7072 offers 72 h realtime recording with 96 h of total recording time. The SRT-7168 and SRT-6000 recorders offer 24 h continuous realtime recording. The SRT-7168 offers the flexibility of selecting up to eight different recording speeds each for T-160 and T-120 tapes, and has a recording/playback capability of up to 168 h. This is ideal in situations where an entire day or week (seven full days) of recording on a single tape is required. The SRT-6000 offers three recording speeds and has up to 40 h recording capability.
Security managers will also benefit from the master/slave eject and clock adjustment, which can be controlled by a master VCR. This is especially useful when multiple recorders are used in large store and casino installations. In this kind of application, all clocks are accurately synchronised by the master VCR.
