A monitored home security system requires the usage of two-way communications between the security system and the 24/7/365 monitoring center waiting for the alert signals.
What do you believe will happen when a robber, burglar or home invader cuts the telephone line before breaking into a home or business with a monitored security system?
- How long will it take a neighbor to notice the problem and then call the police?
- If it happens while you’re home, how long will you wait for that potentially life-saving confirmation call from the security company (which will never arrive)?\
While wondering about those questions, ask yourself this question: “How long will it take the intruder to either take something valuable or harm your family?” Those are precious seconds that are being wasted as the criminal makes his way through your home.
A common problem with many homes today is that the telephone line is easily accessible from outside of the house. Some states have regulations where the phone lines have to go straight underground and not be exposed outside, while others enter and exit the house through the roof and stay far above the ground. Take a look at your situation and see if your phone line is accessible from the ground.
It’s not a secret in the criminal industry that cutting a phone line means that if a monitored home security alarm goes off during the robbery, the emergency signals won’t be transmitted and the police will not be dispatched to the scene of the crime unless you or a neighbor call them.
It’s also known that cutting the phone line will most likely not set off any alarms in the house or at the monitoring center. That’s because even today phone lines can be accidentally cut or brought down in high winds and ice storms. There are many simple reasons for a phone line to be temporarily unavailable, and because of it being cut by a robber or home invader is next to last on the list. There would be too many false alarms if monitoring centers had to dispatch the police every time that a telephone line were to temporarily go out of commission.
So for the burglars, they know that it will still be loud and noisy when the security system is triggered when they break into the house after cutting the phone line. The alarm itself will still work and be triggered like it normally would except for the fact that the monitoring center would not be notified of the robbery. The robber would just have to run over and disable the actual noisemaker (usually by smashing it or ripping it off the wall), and then they could take their time looting your house.
If your monitored home security system does use an exposed telephone line outside of your house, how can you stop robbers from cutting the line and stopping the transmission of the emergency signal?
One trick is to place official stickers from your home security company on the telephone box outside of your home. This will scare away a lot of robbers alone. Most home security companies will gladly let you have a few extra stickers for free to place on the telephone box and on a few of your windows. If they don’t, then check on eBay for people selling the stickers and acquire them that way.
Of course, you don’t need to have a security system to cover your house with stickers and making the robbers think that you do have a working system. If you want to try to trick them that way, the newer the stickers and better known security company, the better.
The other way to protect your exposed telephone line is to use a cellular back-up system with your monitored home security system. Most of the national home security companies offer such an option as a back-up should your home phone line be temporarily unavailable for any reason. This uses the cellular signals to transmit the information to the appropriate monitoring center, so your home needs to be in range of cell phone towers to use this option.
As technology continues to advance and wireless technology becomes better and more widely available, the cellular transmitting devices will be the primary way that monitored home security systems stay in communication with monitoring centers, and using a physical wire to carry the signals will be a back-up option or reserved for those who want a more secure way to keep their home monitored.
As foolproof as it may seem, there is a way for robbers and burglars to get around the cellular back-up device. If the intruder has access to a cell phone blocker or jammer, it stands to reason that the intruder can use the jammer to disrupt the cellular communication between the home security system and the monitoring center. The security system and alarm will still go off if any of the sensors are tripped, but no signals will be sent to the company monitoring your system.
Do take note that the Communications Act of 1934 made it illegal to interfere with the public airwaves. It is also illegal to even own such a jamming device here in the United States.
If you do have a cellular back-up system and do believe that somebody is trying to break into your home, keep an eye on your personal cell phone. As long as it stays connected to the system, then the intruder most likely does not have a cell phone blocker. That would also be a good time to call the police and let them know of suspicious activity outside of your home. Don’t wait until the home security alarm sounds before you take action.
