COVID-19 Alert To DIYers: COVID-19 has severely affected supplier inventory. Product availability, at the moment, is in flux. If you order today, depending on the product, there may be a significant delay in shipping it to you. We apologize for any delays, and assure you that products will be shipped as soon as we can get them. Before COVID, we had significant stock of nearly every popular product that we sell. But demand has outpaced our supplier's ability to meet it, and has exhausted the stock we had purchased to meet increased demand during the government-mandated lockdowns. If you need the product right away, it is unlikely we will be able to accommodate you. For that we apologize. We ask for your patience as we all navigate this unique situation together. Be nice to our employees, they are doing their best to answer your questions and get your product to you as quickly as they can.
Regarding Shipping: Like our suppliers, shipping companies have been deeply affected by the COVID-19 epidemic. Please understand, at the moment, shipping speeds are varying from their promised times. While we ship most items promptly, UPS and USPS, are often not getting products to our customers within the promised timeframe. We are unable to offer refunds for slower shipping at the moment, as this is not within our control. We pay for the shipping speed requested, and, at the moment, our shipping partners are unable to meet their own standards of speed and reliability (this is true of overnight as well) We apologize for this, but can't do anything about it. Please be aware, however, that shipping speeds still matter. While 3-day shipping may, sometimes mean 4-day shipping, it will still be faster than Ground. If you need your product quickly, please choose faster shipping, as it will be faster. But do not expect to get the product in the expected timeframe.
To installers: We have seen an uptick in orders from individuals we suspect to be professional installers. If you are here to get product quickly because you are unable to get the product at your usual supplier, rest assured, we are also out of the product and won't be able to fulfill your order in a timely manner. Like our end-users, we will be delivering products as soon as we get them in.

Great Residential Motion Sensor!
Submitted on

The Qolsys IQ Motion-S, or QS1231-840, is an outstanding motion sensor to use if you have a 319.5 MHz IQ Panel 2 System. It works great with both the standard version of the Qolsys IQ Panel 2 and the 319.5 MHz version of the newer Qolsys IQ Panel 2 Plus. Since this is an S-Line device, it will use rolling code encryption whenever it is paired with a compatible IQ Panel 2 or IQ Panel 2 Plus System. This makes it a simple, yet secure device that is a great choice for basic residential use. That is why we give it 5 Stars.
One great aspect of the Qolsys QS1231-840 S-Line PIR Motion Sensor is that it offers a very good wireless range. In an open air environment, it can technically communicate from up to 600 feet away from the panel. Qolsys recommends using it from 100 feet or less from the panel if possible, but our technicians have found that most environments will allow the sensor to be used from up to 150 or even 200 feet away. Just make sure you test the sensor if you are trying to use the device further than 100 feet from the panel.
For a PIR motion sensor, the Qolsys QS1231-840 does offer a relatively smaller coverage area when compared with similar devices. Its specified range is just 30 feet by 40 feet when mounted at a height of 7.5 feet. However, the device does indeed detect movement reliably from within this coverage area. And most homes won't really need an interior motion sensor with a super large detection area anyway. With that in mind, you really should have no problem using the QS1231-840 in a residential environment. It even offers pet immunity for small animals weighing up to 40 pounds!
Bottom line, we are impressed with the Qolsys IQ Motion-S, and we think it is a strong all-around residential PIR motion sensor. It gets a 5-Star Rating.
