Jam Detection Update
RF Jamming is a technical reality. All devices that use wireless communications protocols can be jammed. The good news is, a) this is *not* a known attack vector for home security, because it's not a reliable way to enter and move about a home undetected, and b) we have a jam detection algorithm that is being constantly tuned and updated behind the scenes, which notices if someone is trying to jam your system and alerts you. More on that below:
A little tech talk:
First we'd like to highlight one of the most annoying issues in detecting jam attacks: False positives are a huge problem. Radio signal "noise' is everywhere and intermittent. So for some customers these alerts could become annoying -- and potentially harmful if they created the incorrect feeling that their system isn't working. We are constantly tuning our detection algorithm to get better and better at differentiating between normal, ubiquitous RF interference and actual, concerning jamming activity without frustrating you with a barrage of nuisance alerts.
Second, jamming without being detected would be extremely difficult, as is clear in the Youtube video. The jam detection was triggered several times by the tester. Our system's array of multiple sensors and cameras (layers of protection), wireless communications protocols and jam detection algorithm work together to make it very hard for anyone to interfere with your system undetected.
Here's why:
The jamming demonstrated is under controlled conditions, with the "jammer" in close proximity to the base station and the sensor which is transmitting. Our testing shows that moving the jammer to another area away from the base station and having the sensor closer to the base station, the sensor could still communicate with the base station. Also, if the jammer is tuned too close to our transmission frequency, as it moves closer to the base station, it will trigger the RF jamming warning. In other words, prior knowledge of the layout of our motion sensors, door sensors and base station in the customers home and a rehearsal of how to move about the home would be necessary to confidently select a frequency that will both jam and not be detected -- let alone on the first try. Plus they would have to keep the jamming interference in that range for the entire time needed to pull off a burglary, while continuing to avoid detection. It's not impossible...but we're continuously improving our system to make it increasingly impossible.
We frequently tune our detection parameters and release security and usability updates. We are in the process of another round of detection algorithm tuning which will continue to refine our ability to differentiate between the brief interference noise that typically occurs in many homes, and actual bad actors. This update has been in the works for a while -- it's currently in beta and will be released remotely in a month or so.
Also, SimpliSafe already offers video verification -- an opt-in service where, in the event of an alarm, our professional monitoring center views video from your home, prioritizing it for the police. This enhances police response times when real alarm events are in progress, and cuts down on false alarms and unnecessary police dispatches. In the near future, we will offer video verification for potential interference events, where experts at our monitoring center can review footage and determine if police dispatch is warranted.
Finally, a reminder (found in this CNET article):
"The most likely burglary scenario by far is the unsophisticated crime of opportunity, usually involving a broken window or some other kind of brute-force entry. According to the FBI, crimes like these accounted for more than half of all residential burglaries in the US in 2017. The wide majority of the rest were unlawful, unforced entries that resulted from something like a window or a garage door being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn't even track those statistics.'
We are a company that focused on protecting you, which means we work on protecting you against even unlikely scenarios like this.

I assume that is easier said than done, but I just thought I'd ask.

Now a rolling frequency would probably do the job. Of course, every single piece of equipment would have to cost at least 10 times as much. And none of the existing hardware would work. SS so enjoyed the last bout of non-compatibility, I'm sure they are eager to do that again.

The more assurance you want the bigger the check you're going to need to write. What is the proper balance? Each has to determine that for themselves.

It was all a big whooptido years back when SS2 was the current system. But, just like this deal with SS3, I am unaware of any reports of this actually happening to someone outside of a YouTube video.
Point being, stop worrying.

Someone simply kicking in your door for a smash and grab is more likely, many times over, than someone knowing you have this system and actually successfully jamming your system.

No alarm.
Later on I did get an interference text and email. But that was at least 15 minutes later and only twice out of four jams. This was only a low power cheap transmitter. A more expensive, more powerful transmitters would be much more effective.
I've removed my simplisafe warning signs and replaced them with Brinks so as no not advertise my alarm system and it vulnerability.
Is this problem the same with all wireless alarms? Or is simplisafe more prone to this.
I did call tech support and she said she never heard of this vulnerability? I armed my alarm and she placed it in test mode and we went thru the sensors and i was able to defeat several sensors. However, it depends on how far away I was from the sensor. Again I believe this was due to the low power transmitter I purchased.
I think Simplisafe needs to address this and an update.

To make matters worse, I noticed a strange individual parked directly in front of my home the day prior (I caught him walking in front of my residence appearing lost the day before). I was going to report it to police the second day I saw him, but while his vehicle was new, it had no plates on the front or back - not even dealership printed. Those two days, my Internet went down soon after (and my ISP confirmed there was no scheduled maintenance). I also woke to my alarm being off the day before yesterday when I check it nightly at the Keypad and by App before bed. I never go to sleep without doing so. But, I do not believe that fits the scope of these vulnerabilities, capabilities (or, instead, how it works).
I was under the impression that one of the other sensors would activate if you were to bypass an Entry Sensor (Motion, etc.), but now I am reading different accounts of this presumption.
Anyway, what a day to have my primary camera need a fix, and I had a necessary appointment. I returned home to find something moved in my home office (I arrange things very carefully - part OCD, part backup to know if anyone has entered without the security cameras or alarm).
All of the above makes me wonder if this thing is catching on. While I take precautions (i.e., not advertising the system, making the Base Station challenging to find, instant triggers, covering the SimpliSafe logos, etc.), the one thing I have always disliked is the Base Station's announcement - "SimpliSafe On, Home." I know I can silence it; however, it is advantageous to hear inside when arming and disarming the system, especially when I plan to remain on the first floor and not the second or third. I never thought one could hear it due to the Base location. However, I just went outside, armed the system, and could listen to the announcement - with my window closed.
A stretch or paranoia, possibly, but I do know someone was in my office yesterday during the time I was gone. Something I never go near (purposely, it is the fail-safe), but appears to be of importance was moved.
Now, on to look through 4 hours of footage of my other cameras to see if they captured anything. I am still not overly worried, but until this is resolved (if ever), I will make sure to have someone present if my cameras are ever down again.

Were you able to find anything on your cameras? (would understand if you cannot answer for privacy reasons).
I hope you've ruled out anyone you know/trust who knows you have SS. Otherwise, if you've prior taken steps to not advertise signs, etc, how would someone know you have SS?
