The VT335S 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 VT335S CAN bus extender.

Cameras

The VT335S 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 VT335S 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.

Configurable logic

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.

Access Control

With the addition of the 1-wire interface and the VT107 RFID Reader an access system can be constructed. Registered cards can be added to the database

Then we can setup a simple control logic scheme. For example, we want to activate an electromagnetic door lock if any assigned RFID card is used or an Exit button, connected via a dry contact input, is pressed.

SNMP

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.

Sensor Charting

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.
