Adding my list of Pros and Cons:
PRO
-Cost: this package is a discount off a comparable package directly from Simplisafe. The monthly monitoring cost is as low as $14.95 a month with no contract. You can even go without a monthly fee if you simply want an audible alarm. You may also save on your Homeowners/Renters insurance.
-Monitoring: SimpliSafe contracts with a responsive, reliable monitoring company.
-Setup: quite easy. The sensors come pre-programmed and attach quickly with adhesive tape or screws. You can easily purchase and add sensors to your needs.
-Components: Motion sensors, door/window sensors, CO2, smoke, water, glass breakage, and temperature sensors , keypads, and remote activation keyword are available.
-Wiresles: the components are all wireless allowing you flexibility and ease of installation. Communication with the monitoring center is via cellular connection, protecting against cut/downed phone or broadband lines. Phone backup (built in jack) and a broadband option (at a cost) are available. Most components run off AA or watch batteries and warn of low battery situations. The base station keeps battery-backup charged in the event of a power outage or disconnection.
-Flexibility: the system can be relocated to another property should you move. Additionally, you can add sensors (if close within range) to outside structures on your property such as sheds, trailers, garages. Sensors can be added to items such as gun closets or medicine cabinets. You can choose alert-only options (such as for a medicine cabinet) or instant trigger (eliminates the delay) on a per-sensor basis.
-Fire/CO2/Freeze/Flood Monitoring: if these components are added, they are monitored as part of all pricing tiers.
-Remote access: available at a higher cost, you can monitor, configure, and control the system with your SmartPhone or website.
-Customer Service: excellent friendly service by phone or email. Many issues can be resolved instantly. Email and website support forums have most answers available.
CON
-Cost: unless you live in a very small home with limited entry point, you will need to purchase additional sensors. To utilize remote monitoring features and alerts, the costs increase to up to $24.99/month.
-Monitoring: the system is proprietary. Should you be dissatisfied with their provider, you cannot activate with another monitoring service. Should SimpliSafe go out of business, you may be left with a useless system.
-Setup: professional installation, if you so desire, is not an option. The sensors are a bit bulkier and visible than a wired alarm.
-Components: the glass breakage and motion sensors can be problematic for people with pets. There is presently no camera integration. You will be replacing batteries periodically for the life of the system.
-Wireless: if an individual component goes dead or the system looses cellular connectivity, you are left vulnerable. Remote areas without a T-Mobile or Verizon signal may find this system of no use.
-Remote access: available at additional cost, the website and app are functional but clunky.
-Flexibility: there is no integration with Home Automation systems such as Wink or SmartThings.
Smash and Grab: if a their locates and destroys the base station before it sends a signal, the breakin will go unrecorded. It is probably best to put the base station where it is secure but still receives a signal, while adding the external 105 dB siren.
Customer Service: only available by phone until 6 EST. email and forum support available 24/7.
