Product Description
The LH60-2020 matrix is an integrated Matrix Switcher/Controller System for CCTV surveillance systems. The LH60-2020 system is capable of controlling a maximum of 64 video input sources such as cameras\character generator etc and up to 16 video outputs such as monitors\digital video recorders etc, and multiple operator sites (keyboards) or graphical user interfaces. The LH60-2020VLD system is an LH60-2020 system with video input looping capability. The LH60-2020VAD system is an LH60-2020 system with audio input and output capability.
Front Control Panel:
The LH60-2020VD has a VFD display screen\control buttons and joystick for pan/tilt. The information that can be displayed on the screen includes numeric values entered, the current site number\monitor number and camera number.
Menu Operating:
On-screen menus are provided for LH60-2020 system setting and programming using a system keyboard and No.1 monitor.
Video Switching:
LH60-2020 full crosspoint matrix provides switching of all cameras to all monitors. Any of the cameras can be preset scenes, and can be called by any of the monitors at any moment. Switching can be called by operator keyboard's request or by automatic actions such as tours\system salvos\alarm response or timed events.
Tours:
A tour sequentially displays a selected series of camera inputs on any monitor. Each camera is displayed for a set period of time (the "Dwell Time"). A tour can include the same camera multiple times, and is reversible.
Monitor Tours:A monitor tour is a temporary sequence of cameras programmed, via a keyboard, for the called monitor. A monitor tour may contain 64 cameras, with an independent dwell time for each camera.
System Tours:A system tour is a pre-programmed tour that is defined in LH60-2020 setup menus. 64 system tours may be pre-defined and saved for callup, by operator or automatic timed events, to any monitor at any time. Each tour may contain 64 cameras, with a dwell time, preset camera scene, and auxiliary action for each camera.
System Salvos:
Cameras may be grouped into system salvos and switched simultaneously to a contiguous group of monitors. 64 system salvos may be programmed for callup. A maximum of 64 cameras can be included in a system salvo, each with a preset scene and auxiliary action.
Alarm Programming:
LH60-2020 includes 32 built-in alarm contact inputs. Two Alarm Interface Units can be cascaded via an RS-232 port to provide a maximum of 128 alarm contacts. Cameras and monitors may be individually armed for alarm response.
Alarm Camera Programming:Individual alarm contact can be programmed for a specific camera or camera salvo callup on alarm, including a dwell time, preset camera scene, and auxiliary action for each camera.
Alarm Monitor Programming:Individual alarm contact can be armed for display on a specified monitor on alarm. Different alarm display and clearance modes may be programmed for each monitor.
Alarm Relay Output:An alarm activates a form C relay, which can be used to control a VCR or other external equipments.
Timed Event:
A maximum of 35 user-programmable time slots, called events, can be programmed. Each event can be programmed for automatic callup by system tours to any monitor at a specific time of day, on different days of the week, week after week.
Input Identification:
The LH60-2020 provides on-screen identification for all video inputs. The date\time\camera number\camera and monitor status, and a 10-character/number programmable title can be displayed on the screen.
RS-232 Ports:
LH60-2020 system provides three RS-232 ports, which can be expanded to 12 RS-232 channels via the LH40-83X-4 Port Expanders. Any of these channel is a universal I/O port for connecting with LH50-78D/79D/83D keyboard\Alarm Interface Units and external computers.
Receiver Control:
LH60-2020 can control receivers in LH control code or RS-232 protocol. LH difference digital signal or RS-232 protocol enables to realize remote control of fixed or variable speed pan/tilts\motorized lenses\auxiliary actions, and preset scenes at suitably equipped sites just in separate code lines.
System Partitioning:
Partitioning of individual user access to specific system resources is provided as security feature. Programmable partitioning limits keyboard access to monitors, keyboard access to cameras, and monitor access to cameras.
Keyboard-to-Monitor Lockout:Prevents selected keyboards from accessing selected monitors.
Monitor-to-Camera Lockout:Prevents selected monitors from displaying video from selected cameras in the system.
Keyboard-to-Camera View Lockout:Prevents selected keyboards from calling up selected cameras to any monitor for viewing and/or controlling.
Keyboard-to-Camera Control Lockout:Prevents selected keyboards from controlling remote functions on selected cameras.
Keyboard Priority:
Keyboard Priority Levels:The system keyboards can be set to one of the operating priority levels from 1 to 32 for distinguishing the operators with different priorities. The higher priority keyboard operator is able to interrupt the camera operating or locking of the lower one.
Keyboard Limit of Accessing to System Menus:To set that specific keyboards are capable of accessing to system menus for programming or setting system data.
Keyboard Limit of System Reset:To set that specific keyboards are capable of performing system reset to clear all the user-programmed data.
Camera Lock:
Keyboard operator can lock a selected camera to a selected monitor for exclusive control of the camera and monitor to avoid the monitor switching and camera control caused by the interference of other keyboards. If a keyboard priority is ranked as one level of 1 to 32, the keyboard can lock or unlock a specific camera. On the other hand, if the keyboard is set as 0 level priority, it can not perform camera locking.
PC Application Program:
Run LH70 series of graphical interface software in a PC of Windows2000/XP or more advanced platform to realize system operations and programming of LH60-2020 based on electronic map and device-tree.
The software can display icons of camera, speeddome, monitor, alarm contact, AUX switch in multiple electronic maps, and can switch and control cameras just by clicking these icons, whose parameters have been set beforehand. With an analog full-function keyboard, one can set and program the system. The status of alarm contacts can be displayed directly on the electronic icon, and can activate camera switching or AUX switch's activities when alarms are triggered.
Memory Retention:
User-programmed data is stored in memory and is battery-backed for a minimum of five years. The user data stored includes on-screen identification of all inputs, system tour sequences, system salvos, event timers, alarm programming, and time/date.
Satellite Site Control:
With RS-232 ports of matrices being connected, multiple matrices can control mutually after their numbers and signal output channels of the satellite site have been appointed in menus. Control can be simplex or duplex, and at most 64 matrices can be connected with different types.
Multiple Sites Alarm:
With RS-232 ports of matrices being connected, alarm output ports being appointed in menus, alarm signals of one matrix can be transmitted to another matrix to activate alarm. Thus an alarm network of multiple sites forms.
