Essential Info

Remotely protect and monitor your vacation home, cabin or cottage, with the Sensaphone 400. This device detects potential disastrous problems and monitors environmental conditions, calling out up to four different numbers when a change or abnormal condition is detected; it also allows you to remotely control devices via your telephone or cell phone. It is simple to install, program and operate; no changes to standard electrical or telephone service is required.

Three sensors are built-in to the Sensaphone 400 to detect temperature, loud noise and power failures. With four hardwired inputs available, additional sensors can be added to monitor water leakage, humidity changes, outdoor temperature, glass breaking, motion detection, and opening windows or doors. You can even monitor wind, rain, and freezing outdoor temperature conditions. Sensaphone offers voice message customization to describe received alarms. For further peace of mind, if a phone is accidentally left off the hook, the Sensaphone has a line-seize feature to automatically re-establish a dial tone to make an outgoing alarm call. A built-in microphone allows you to call in and listen for live activity at any time.

The relay output on the Sensaphone 400 allows you to connect your thermostat so you can call in and set the temperature hours before you arrive, ensuring that the house is comfortable and cozy from the moment you walk in the door. This device is INSTEON compatible so you have the freedom to periodically call in to turn on lights and appliances, giving your home that lived in look while you're away. If you want to grant entry access to trusted neighbors when you aren't around, connect and electronic door strike to remotely lock and unlock your front door.

The Sensaphone 400 comes with a plug-in AC power supply; however, six C batteries (sold separately) are required for calling out in event of power failure.

    I am using this device for 6 years in a remote location. It saved me some big bucks controlling temperature, electricity, smoke, water. I can easily operate it from the distance over the phone. Mostly using it in winter when calling to switch the thermostat from the vacation mode to the regular one, so coming to the already warm house. It calls you up to 4 phone numbers if something is going wrong: power failure, temperature too high or low, water in the basement, smoke in the house - depending on what sensors you are connecting to it. I really love it and do not regret any penny put in it.
    NORBERT -- porter, IN   10/7/2013
    Initial findings-very easy to set up. Very user friendly. Test run worked well. Will know more when put in actual use.

    Sal D. -- Maine   1/5/2012
    Excellent while it worked, but stopped after one year. Should have invested in a better system. Also, waterbug I bought for it useless.
    ROBERT J. -- carmel, NY   12/5/2011
    I was most impressed with "Manual of Instruction" for the Sensaphone 400. Easy to install and worked on the first try. I plan on adding three more monitoring devices in the near future.
    DON -- orchard, NE   10/24/2011

    LYNN -- beaverton, OR   8/3/2010
    I work in a research facility, there is a need to monitor many diferent things. At present we have installed 8 units. They're very flexible, and easy to program. We measure relay contacts in fire alarm, scientific equipment, and temperatures in freezers and animal rooms. My next project is to monitor -20C. It's a good product. Lynn - Telecom Engineer

    RAYMOND -- eastchester, NY   3/29/2010
    great....programming and use easy; changes made without a problem....the User's Manual could use some minor clerical/style changes....i installed in a few hours and started using immediately to control Radiant floor system in a Vacation home. Ray Del Savio
    JON -- meriden, CT   1/9/2010
    The sensaphone works exactly as described. Initial set up was easy - the detailed intsructions for the advanced options were clear and easy to follow. I do have an extensive technical and computer technology background. People not having that skill set might be a little overwhelmed by the length of the instructions and multitude of options. For the requirements I have, this product is the optimum solution for both features and price. I am totally satisfied with the purchase.
    DAVID -- cogan station, PA   1/5/2010
    I have used other Sensaphone products at home and at work and this one is also excellent. Easy to use and setup. Shipped fast.
    CAMERON G. -- yellowknife, NT   1/5/2010
    Extremely easy setup and very reliable. 3rd 400 I've purchased. Had one at home and one at the office, and now one for my son's home! After all these years though, I wish Smarthome offered better shipping to Canada and honored the digital coupons they email monthly to my Canadian email address.
    GRAHAM -- tucson, AZ   1/5/2010
    easy to install works perfectly.
    SALVATORE -- peabody, MA   12/18/2009
    I like this system. It took a few hours to set up and test and I am having issues with it calling the additional numbers. Overall a good product as advertised. The nicest feature is that you can call in and get the temp, power status, and can listen in with a phone call. I had water damage two years in a row and hope that this will keep it from happening again.
