Video Switchers

	Combining the patented ID-Code, I-Decoder, and Framelock technologies, the patented Serial Video offers transmission of multiple I.D. coded camera signals by serially sequencing the camera's signals at a field or frame rate, making it possible to record, memorize and display large volume of cameras on large volume of monitors through single transmission line.
	ID-CODE & I-DECODER The patented I-D Code system consists of invisible 16 bit binary code injected into single horizontal line (H12) within the vertical blanking period. Elbex cameras with built-in ID-Code and in-line encoders incorporate DIP switch for setting an I.D. number from 001-999.
	Thereby, the ID-Code becomes a identification code hat does not obstruct the display, yet, it is always present. An I-Decoder with detect the ID-Code and can retrieve any or a group of I.D. coded video signals from a VCR playback or from a serially transmitted video signal.
	FRAMELOCK EXT. SYNC The patented Framelock ext. sync system provides for transmission of vertical sync pulses (25 mhz CCIR or 29.97Hz EIA) through the video coax cable to the cameras, in reversed direction to the video propagation.
	The Framelock therefore synchronizes all the cameras of a given system by locking all the camera's filed and frame sync pulses to the very accurate Framelock time base. For large systems at distant, Framelock can be propagated via twisted pair network, telephone lines, and fiber optics.
	FRAME SWITCHERS & SERIAL RECEIVERS Large volume of framelocked, I.D. coded serial video signals sequencing at field or frame rate can be recorded and transmitted over a single coax, via fiber optics or through microwave link. It takes only a single such video transmission line to propagate up to 48 camera signals to as many VCRs and monitors as desired.

EXZ9300	Four B/W frame switcher models depict very high horizontal resolution of 380 TVL, displaying crisp clear, hairline detailed picture, far above the resolution of B/W playback signals.
EXZ9400	Four color frame switcher models permit the mixing of B/W and color camera signals and depicting high color horizontal resolution of 280 TVL, well above resolution of a VCR playback composite color signals
Features	Y/C (Super VHS) Video with higher color resolution and Y/C output for high resolution color monitors. The 48 keys and 8,16,32, or 48 multi-colored LED's offer simple manual selection of a camera, selective record/playback signals or bypass of a camera from the sequence or the alarm process. Intelligent homing for single alarm or sequencing multi alarms (at frame or preselected time) along with switching over the VTR's recording mode from time lapse to real time. Frozen monitor display of the alarmed channel along with frozen time and date provide the operator with instant information of the alarm initiation. For large systems having multiple monitoring and control sites the frame switchers can be connected in cascade to lock and externally synchronize the entire system, as well as, to transfer on-line data to unify the time/date, text and I.D. for all the sites. Both the EXZ9300 and EXZ9400 series provide in addition to field or frame scanning a conventional manual/sequential switcher output for monitor display or for VCR recording. Up to 48 alphanumeric white characters with black borderline in two text lines can be displayed on the screen along with the I.D. Time and date display are accurate (+- 30 sec/month) time/date displaying month, day, year, along with hour, minute, and seconds can be positioned throughout the screen in single or dual lines, coordinated with the text and I.D. display positions. The EXZ9300 and EXZ9400 series are designed for use with any 8mm, VHS, S VHS and with most time lapse recorders. The EMDU94 accepts trigger signal (generated by most current time lapse recorders) switch from one camera to next in sequence.

EID9300-EIDQ9308	Three B/W serial receiver models depict very high horizontal resolution of 360 TVL, displaying crisp clear, hairline detailed picture, far above he resolution of B/W playback signals.
EID9400-EIDQ9408 Color	Three color serial receiver models permit the mixing of B/W and color camera signals and depicting high color horizontal resolution of 260 TVL, well above the resolution of VCR playback composite color signals.
Features	Dual independent monitors/VCR outputs Unlike the frame switcher the serial receivers offer dual independent setting for simultaneous displaying of separate signals through dual monitor outputs. Main monitor output provides for manual or video I.D. coded signals, as well as, the multi pages of split screen output of the multiform serial receiver model EIDQ9308. Second monitor output also provides for monitoring of manual, sequential of the serial video as well as for direct monitoring of VCR playback and pause signals. Standard BNC connectors are used for both monitors and the VCR hookup. Recording signals (VCR output) signals can be locked to either monitor 1 or monitor 2 output.
