PYGUARD Door & Sensor Monitor With LTE-M For Remote Security Applications.
PYGUARD Door & Sensor Monitor With LTE-M – PYGUARD, made by high end access control manufacturer, Steinbach & Vollmann GmbH, delivers electronic status monitoring of doors and external sensors using low-cost LTE-M IoT SIMs, NB-IoT or 410-450MHz radio communications.
The monitor reports changes in the status of a door or connected sensor to PYSUITE software, allowing remote monitoring of entry points across secured areas when an electronics access control system has not been installed.
PYGUARD’s integrated reed contact provides door status monitoring, while an external input supports pulse or changeover contacts from devices including gas and fault detectors. PYGUARD also monitors tamper and battery status, with events available through PYSUITE or the PYAPP application.
The PY9053 version incorporates an external antenna connected by a 3m cable and SMA connector, allowing the antenna to be positioned independently of the monitor where radio conditions or the installation location require it.
The unit has an ABS enclosure, screw-on fixing and an operating temperature range of -20C to 65C, with relative humidity rated to 95 per cent. The enclosure is rated IP65 against dust and water though STUV only claims a rating of IP54 for the overall system, likely to cover use of that SMA connector mentioned earlier.
Batteries deliver a service life of up to 5 years before replacement, while an optional 230V mains connection can be used with rechargeable battery backup.
