RF jammers and frequency interference
Anti-jamming alarm system: an RF jammer won't stop it
Before breaking in, an experienced intruder switches on an RF jammer: a wireless alarm panel loses its radio link with the sensors and goes blind. VNS Manager is hard-wired: the cameras keep streaming, the jamming is detected and the alarm is triggered.
Disturbance devices cannot compromise system operation. Any interference is detected and reported immediately.
Recording begins before the alarm is triggered, capturing the moments leading up to the event.
Footage is analysed directly within the system, without relying on external servers.
In the event of theft or tampering, the information will be unreadable.
What is an RF jammer
A compact transmitter that blocks wireless signals
-
Multi-band jamming
It transmits noise across the GSM, 3G, 4G, 5G, Wi-Fi and GPS bands, overpowering legitimate signals: wireless links no longer get through.
-
Easy to obtain
It is available online, it is portable and it activates at the press of a button.
-
It blinds wireless alarm systems
In a wireless alarm system, sensors and control panel communicate over a radio link: with the jammer active, the link drops and the panel no longer knows what is happening.
-
VNS Manager keeps watching
The cameras are connected by cable, so the jammer has no effect on them. In fact, the jamming itself triggers the alarm.
Frequency interference test
Before breaking in, an experienced intruder activates a frequency disturbance device
Activate the device and see how a wireless alarm system and VNS Manager respond to frequency interference.
Devices like this are now easy to purchase and can interfere with a broad range of frequencies.
Wireless alarm
Radio
Four motion sensors connected wirelessly to the control panel.
- Communication with the sensors is lost
- No alarm is triggered
- No call. No email alert
- The intrusion is only discovered the next morning
Some wireless alarm systems can detect frequency interference. But once communication is disrupted, they can no longer monitor what is happening.
VNS Manager
Hard-wired
Four hard-wired cameras remain fully operational despite frequency interference.
- Frequency interference detected
- Warning lights. Audible alarm. Voice message
- Email and notification sent to the site manager
- Call initiated, with footage capturing the 10 seconds before the event
