Burglary may seem like a difficult task, but it it can be broken down into a series on simple steps when taken can increase a burglars odds of success. One of these odds is bypassing home security. Today I will describe to you the flaws of modern home security systems.

Historically & even today most home security systems connect to the security company though physical telephone cables.


However these can easily be disabled by cutting the exposed cables with insulated wire cutters. Because of this modern systems are switching over to battery backup systems with cellular connections.


However these too can easily be bypassed with the right investment.

For $350 you can get a cell & 2.4ghz wifi jammer. GET the wifi jamming option as it blocks 2.4 Ghz frequency which is unregulated frequency by the FCC for consumer products meaning the vast majority of proprietary systems will use 2.4 Ghz for their wireless frequency as its one of the few options. Bluetooth for example uses this frequency.


This system will bypass any cell based home security system preventing it from sending a message back to the security company giving you at a minimum 1 hour of access to a property before the battery runs out. It has ample range & strength to penetrate any home.

Now that you know of this flaw how could you guard against it? Well, sadly there is no realistic way to guard against it. You would require a faraday cage tower going 40 meters into the sky to allow the cell system to communicate without having it's signal scrambled.

However there are steps you can take by making your property less inviting to thieves. Even if a thief has a cell jammer, why would they pick a home which has a security sticker on the outside when they could go 1 house over to one which doesn't.

Information not intended for thieves, be nice :)

Couple things to be aware of

  1. Underground utilities nullifies wire cutting.
  2. Ensure the system is not setup to automatically call if a signal is not detected.
  3. House has a gas generator or a battery bank array.

The one unknown is if the system is armed and you are within earshot of neighbors. You trigger the alarm and you are are screwed.

An easy way around this is to compromise the house through the garage. Take a drywall knife with you and cut the wall from the garage into the home. Most newer homes are moving away from inside motion detection and only monitor doors and windows.

Check for houses that have the break box on the outside. The same for businesses as well. Trip the main breaker, wait 2-4 hours for most battery systems to discharge and then go in.

The cell jammer is an excellent tool. I would research Raspberry Pi wifi jammer. This is an excellent tool for most remote cameras. Take a high grade laser with you to point at cameras. Hopefully you have done your research and their is no dog or anyone home. Make sure you are in good athletic shape.

The box cutter idea is great, the issue is some people might not have the ability to pick locks. A tried & true method is to use a pry-bar to break open basement windows & crawl through there. Basement windows normally just have a small plastic or metal latch you can easily break to slide the window open without needing to break the glass.

But then you have to deal with the security system in this situation if it's wired. Hence the alarm system, however it's often easy to spot the white magnetic window sensor just by looking at the perimeter of the window. I'm surprised how many security companies neglect the basement windows. But if you're overweight this would automatically not be an option for you.

I have installed many recessed window and door sensors. They're in the frame/jamb and cant been seen. Just an fyi. Not all sensors are mounted/installed on the surface.

Former alarm tech here. This is so much wrong with this.

  1. Telephone lines are rarely used now for security monitoring. Fire alarm, no. Most of these are cellular and internet
  2. Communicator Supervision - Most professionally installed system supervise the alarm communicator (device that transmits signals). If this device is tampered with, alarm will sound.
  3. Additional supervision - Most systems have Frequency Jamming supervision. Very common on Honeywell, DSC, Interlogix, DMP and Qolsys systems. If the system detects the frequency is being jammed, it will try to send a signal to the central alarm station, but even if it doesn't reach it, if the system is armed, it will go into alarm and make noise to let everyone within earshot that something is up.
  4. Clearly this is a thinly veilled attempt to bu these "Jammers" Which probably don't even work, and the site selling them was created in 2020 and very sketch.
