Frequently Asked Questions
How does your multi-family leak detection pricing work?
Droplet Duos are $80 each. We can work with you on the price with larger purchase volumes.
For whole-building coverage we offer flat-rate monthly monitoring calculated at $8 per apartment. Install as many sensors as you need.
There is an annual monitoring fee of $30 per sensor. Because each sensor can detect moisture in two locations, we can often use one sensor to protect multiple areas, such as inside and outside of a condensation pan, or under a kitchen sink and under a dishwasher. However, we offer discounted volume pricing, based on the number of units or square footage of your property. This is most beneficial if you are going to install sensors in each apartment.
Can this system pay for itself?
The average leak claim runs over $10,000. The average 100-unit building is likely to have 3-5 of these incidents per year. Remember that this is an average, so half of all buildings will suffer even greater outlays. Over time, the system will certainly save more money than it costs.
What is required to install a sensor?
Droplet sensors are easy to install. No special skills are required, simply peel the backing off the sensor probes and and housing, then press to affix them to the surface you’d like to monitor. Then enter the sensor and probe locations in the Perceptive Things online management platform. Now that area is fully protected!
What is required to install a gateway?
Perceptive Things handles all of the network installation for each building. Working together with staff, we identify the best overall location for each gateway, either placed on a shelf or mounted on the wall with three screws. Because our gateways use cellular LTE to communicate with the management platform, they only need to be plugged in to an electrical outlet and they’re ready to go.
Does this system require Wi-Fi?
No. The Perceptive Things system runs on its own independent network that is completely separate from building or resident’s Wi-Fi networks. This increases security, reliability and battery life. It also greatly eases provisioning and installation because the sensors work immediately out of the box, no tracking down network names or keeping up with changing passwords. Having the two systems fully separated creates a natural firewall, greatly improving security for both networks.
Does this system interfere with Wi-Fi, Bluetooth or cell phones?
Because the Perceptive Things LoRa network runs at 900 MHz, it does not interfere with Wi-Fi and Bluetooth, which use 2.4 GHz (a totally separate radio frequency band) or cell phones which use licensed spectrum that doesn’t include 900 MHz. Droplet™ sensors do communicate actively during a leak, but most of the time sleep passively so they generate very little radio activity in the first place.
How often will we need to change batteries?
In typical use batteries will last up to five years. The Droplet sensors use coin cell lithium batteries with long shelf lives, and mostly stay “asleep” unless they detect water, which is how they conserve power.
Will we get low battery warnings?
Yes. Droplet sensors send daily communications to let the system know they are still connected and functioning, along with the current battery level. If a battery appears to be nearing the end of its useful life, that sensor will be included in a daily warning email to managers so that battery replacement can be planned.
