The Room Alert 3S is Avtech’s most economical environmental monitor with the smallest footprint and the highest security features, including HTTPS, TLS, and SNMP v3. It monitors temperature, plus two more environment conditions of choice, which makes it well-suited for small data centers, server rooms, IT closets, or any other location that requires constant monitoring to prevent downtime or data loss. True to its compact form, the Room Alert's lone digital port does double duty. It can take a sensor to read the environment or an adapter to act on it. It can hang from a ceiling or on a wall with no special tools and fits easily in telecom or wiring closets, server rack cabinets, and other locations where space is at a premium. Multiples of this unit be distributed across strategic locations of larger spaces to cover more ground.
