ESP-RJ45 Wired Anti-Jamming Module for Wireless Security Systems – Tuya

An Uncompromising Last-Resort Security

The ESP-RJ45 is not just a simple alarm; it is your anti-jamming insurance. Designed to operate in parallel with your main security system, it takes over instantly if your alarm control panel is neutralized by a radio jammer. Thanks to its direct wired RJ45 connection to your internet router, this module is physically immune to radio attacks that silence wireless alarms.

Guaranteed Notification, Even Under Attack

The strength of the ESP-RJ45 lies in its complete independence from radio signals. It continuously monitors 4 types of security inputs using dry contacts, such as:

• - Jamming detector: To immediately identify an attempt to neutralize your wireless environment (Wi-Fi, Bluetooth, GSM, 3G, 4G, 5G, and the 433 and 868 MHz frequencies used by alarm control panels).
• - Opening detectors (doors/windows): For conventional wired perimeter protection.
• - Wired motion detectors: For monitoring indoor areas.
• - Relay output from an alarm control panel: To be alerted if your main alarm detects an intrusion or anomaly.

As soon as a signal is received, a push notification is sent to your smartphone via the Tuya Smart or Smart Life app. You therefore remain informed of the situation, even if the Wi-Fi and GSM networks are saturated by criminals.

Active Control of Deterrent Countermeasures

Do not simply endure an intrusion—take action. From your mobile app, the ESP-RJ45 allows you to control 2 control outputs, either manually or automatically, to activate powerful defensive equipment:

• - Fog generator: To make it impossible for burglars to see.
• - Siren: Scare intruders away with powerful sounds.
• - Strobe light: To create a startling effect and signal the alert visually.
• - Speaker with Custom Audio: Broadcast realistic dog barking, simulated conversations, television programs, or police sirens to create the impression that someone is present or that law enforcement is arriving.

Why Add It to Your Installation?

Security experts point out that jamming has been the preferred method used by burglars since 2025 to neutralize wireless protection systems.
An all-band jammer (Bluetooth, 2.4 and 5.5 GHz Wi-Fi, Wi-Fi 6E, 433 and 868 MHz alarm control panels, GSM, 3G, 4G, 5G, GPS, etc.) costs only €300!
The ESP-RJ45 addresses this critical vulnerability by adding a wired layer of security that cannot be switched off remotely. It is the only way to ensure that you will be notified and able to activate your countermeasures, whatever happens.
