Sim dialler ...jammer

2012paddy2012

Have a newish hkc panel fitted recently ... Just reading the indo today I see a burglary in blackrock carried out and culprits used jammer. . A nearby resident who saw it tried to ring police on mobile phone but couldn't ring out as the phone was jammed ..... I presume there is an connection available on the panel for a radio relay back up ...... With the widespread use of these jammer the sim text notification of an alarm event is useless .... Are there any radio relay that are priced for the domestic market yet, does anyone know.


Thanks

Some of the stations do have radio options but they are more expensive.

They'd have to know that the household is using a gsm in the first place .
They'd have no trouble sticking on a high vis vest to climb up the phone poll to disable a phone line .
I know with the HKC alarms that you can set up the gsm unit to trigger an alarm if no gsm signal is detected for a certain length of time.

Wireless ip can be jammed and if the power was cut then the internets gone .
UPC lines can be cut .

All methods can be defeated ...

If you see it happening in your estate it would be no harm to set off your own house alarm to attract the neighbours attention .... The more bells the better

Phone lines can be cut. So can UPC or other forms of IP monitoring. However, what you haveto remember is GSM jamming requires no physical or visible tampering. That is what makes it more vulnerable.
In my experience I have seen phone lines cut and I've seen GSM jammed. To date, I have never seen UPC lines cut.

I don't know if they would go to the bother cutting lines etc a lot are ungrounded in housing estates ..... for burglary ..... yeah for industrial units shops I was just wondering is there any way to circumvent the gsm jammer , which would be within the reach of the ordinary joe! Seems not......good area for a patent! Anyone good with electronics !

Some of the internet/3g ones send a "heartbeat" every so often - if it doesn't arrive the call centre gets an alert

Very interesting I have no landline... Tho I only have mobile broadband ! I have the sim gsm dialler on the hkc system I got last year... I see what thunderbird means ... And kool kid but , before these jammers arrived you could be certain that your house was safe when you were away for example , now you would have no idea at all as you wouldn't get the text ! That peace of mind is gone now unfortunately !

The peace of mind is gone. Radio would be the most secure, especially for Shops, Commercials, High end properties.
To use a GSM in any of these situation would be asking for trouble.

I hope they took down the licence plate number and took some photos

There is no radio back up that can alert your mobile !? Using an app or email I presume ....😄

Unfortunately not. Monitoring stations only.

A mix of the two would be best IMO
Gsm and Ip or phone .
It's only a matter of time before they start snipping UPC lines ...
Also GSM jamming may require no physical tampering but it's going to attract more attention when used in a built up area ... When people's phone calls drop what do you think they're going to do ? Walk out of the house to try get a signal or go ask their neighbour if their signal is gone ..

It would be Phonewatch customers that should be concerned most... A gsm jammer isn't going to prevent an external bell from ringing . Eircom don't install these as standard which means customers are relying on the internal siren ... That won't last once the panel is knocked off the wall . But again they'd have to know that a GSM unit is being used

Radio would be the most secure as it would take specialist equipment to block it.
Most expensive out of them all.
Polling a GSM like dual com would also have drawbacks as it needs to drop off 5 times in 15 minutes to be flagged.
I am sure the same will also apply to IP.

to kill the upc all you have to do is pull the main fuse from the esb meter at the side of the house, 10 seconds and its done, no climbing or cutting involved.... its highly unlikely that most people wud have their upc on a ups system....

Thunderbird2

Doing that would trigger a panel mains fault and a line fault . Cutting the UPC line won't register a fault as the voltage is still there

Diggerdunne

if there is a power failure in the area the monitoring company has to check all the line faults and mains faults? how do they distinguish between a power failure and a intruder killing the power?

Thunderbird2

They wouldn't know about the mains fault if the UPC is down and the line fault won't be recognised for a few hours
The Alarms have back up batteries that will keep the system running but not the UPC

altor

All depends on the time that the alarm makes the test call. Most do once in 24 hours. P.W. once a week. Same with a GSM fault.

Lads the criminals will be delighted with all the info on this thread.

Cutting the mains power is also very rare. I have seen this once in the last few years. And in that case they didn't bother with the phone lines at all..
From testing and looking at some jammers I find your mobile does not show no signal. In fact it generally shows full bars. It's just when you go to make a call it doesn't connect. I certainly don't think my neighbours would be out on the road and knocking on doors for this. Re polling you can use duel path devices that send signals to the station at set intervals. However even if the station gets a line fault and missing polls this is not considered an actionable confirmed alarm.

Like wise people who are informed of a GSM that cant be blocked.
Swings in roundabouts.

Guess I'm lucky with the neighbours I have haha . it's only a matter of time before they pick up on these tricks.
