Special order, 5-10 day despatch
The VT825-DC BMS unit for environmental monitoring and alarm in telecoms application with a 48V DC power system. Featuring a web interface and 8 sensors ports, 4 digital inputs , two relay outputs, CAN bus, alarm notifications via SNMP, E-mail, web or beacons, accepts a USB camera or up to 4 IP cameras. Web interface features a dashboard giving overview, simple control logic to set up alerts, notifications and actions and sensor chart displays with data export.
The VT825 series has a built-in web server showing overall status and system tree, the status of dry contact inputs from doors and windows, and an event log
CAN bus Expansion
Connecting CAN devices on a common bus allows you to collect data from a large number of sensors over a large area, or from a longer distance. Up to 32 devices can be added to the CAN interface and this can be further increased with a VT408 CAN bus extender.
The VT825 can display pictures from a maximum of four IP cams simultaneously in several sizes, up to 640x480 pixels resolution or a single connect USB webcam.
Security, Notifications and Alarms
The VT825 authorization is going through the Radius protocols, that highly increases resistance to forced attacks. Notifications and alarms can be configured in “Logic menu” of web-interface using the states of sensors, timers, triggers and so on. In case of a problems the notification scheme can alert user via email, SMS or SNMP, automatically send pictures and data.
The complete status of the unit and / or sensors can be taken through HTTP, SMS, or SNMP, saved on FTP and Syslog servers or on installed SD card.
The Web interface allows you to set up logic rules for alerts, notifications & actions such as to switch on a fan and send an email when a temperature exceeds alarm limits.
All SNMP functions including SNMP v.1, v.2c, v.3 are supported. VT325 has a Built-in Watchdog timer with NTP synchronisation. SNMP Get function supported.
5-level sensor thresholds
Sensors with 5-level thresholds allows direct connection to the SCADA system.The thresholds are usually: very low, low, normal, warning and alarm. Sensor levels can be inverted.
Web interface integrates and displays graphs of all sensor data. The individual graph (seconds, minutes, hours, days) for each sensor type can be selected. RRD tool is used to build an embedded database of sensor data. This data can be accessed via the interface, or downloaded to Syslog or to FTP or saved on SD card. You can compare sensor data using a Multiplot by plotting a few sensor data along each other.
