Watchdog Wi

Watchdog Wi


Features and Benefits

The WDWi system of gateway manager, wireless sensors, and range extenders allows you to monitor your facility for changes in temperature, humidity, and dew point and allows you to fine tune your environment to meet energy efficiency goals, maintain optimal equipment performance parameters and ensure your facility is operating under optimal conditions.

Wireless Monitoring for Your Data Center
Built-In Web Interface

The WDWi receives data from wireless sensors which is displayed on a web interface, accessible from any browser or mobile device. Designed to keep the most relevant information close at hand, the web interface provides direct alarm notification which allows users to quickly and effectively locate areas of concern. The WDWi will also send email alarm notifications and provides trending information to help pinpoint potential trouble spots in any monitored areas. An open protocol approach streamlines communications and allows the WDWi to easily integrate into larger BMS and NMS systems via SNMP, Modbus, or BACnet.

Wireless Sensors

Wireless Sensors

Adding new sensors or relocating current ones is made simple using Geist's Watchdog Wi, which contains an auto-discover mechanism that detects modifications to the system. The WDWi temperature and temperature/humidity sensors are compact and unobtrusive, yet provide an industry leading battery life. WDWi sensors maintain this extended battery life while communicating readings every 10-20 seconds. 

Wireless Temperature and Temperature/Humidity Sensors

Wireless Temperature Sensor (WTS)
Wireless Temperature/Humidity Sensor (WTHD)

The WTS and WTHD are battery-operated digital wireless sensors with a 900 MHz, FCC-certified radio transmitter. The WTS and WTHD provide a temperature output signal from an internal thermistor. Accurate and timely data is provided while consuming minimal power, resulting in a long battery life (5 to 12 years).

Unprecedented Transmission Range

Extended Transmission Range

The WDWi system has an unprecedented transmission range: up to 600 feet indoor, direct line of sight. While this range is more than ample for most situations, sometimes applications require signals to be pushed through more complex physical or noisy RF environments. The Wireless Range Extender (WRE) can be implemented in these situations to add up to 1,000 feet direct line of sight transmission distance per range extender to the application.

Wireless Range Extender (WRE)

Each adds up to 1,000 feet direct line of sight range to a Watchdog Wi solution. Range extenders both send and receive signals, allowing this distance to compound exponentially. This means for every range extender you add to a system, you add another 1,000 feet of distance to your system – the more range extenders you add, the more this distance increases. If you add three range extenders to your system, you can gain up to 3,000 feet direct line of sight distance significantly increasing the distance you can cover between the main gateway and sensors.
