With dual communication through both WiFi and GSM networks, the system ensures reliable alert transmission even if one network experiences issues. The unit supports telephone alarms that can notify you directly of security breaches, while its wireless design simplifies installation without extensive cabling. Available in model variants suitable for AU, EU, UK and US regional specifications, the ER G30 style alarm host provides a configurable security solution.\n\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"WiFi GSM household burglar alarm unit with wireless sensors for home security\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/495\/2025-10-02\/original-image\/1393643255048.webp\"\u003e\u003c\/div\u003e\n\nThe alarm system is built around wireless communication between the main host unit and peripheral security devices. This design approach reduces installation complexity while maintaining reliable security monitoring capabilities across different property layouts.\n\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\nThe main alarm unit houses electronic components within a plastic casing, though specific plastic types are not detailed in the available specifications. The construction prioritises functional reliability with dual communication systems that work independently. The unit includes a backup power system with a 1.5V lithium battery compartment, ensuring continued operation during main power interruptions. This practical design approach focuses on maintaining security functionality rather than aesthetic considerations.\n\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\nWhile exact physical dimensions are not specified, the wireless nature of the system allows flexible placement of both the main unit and connected devices. The 120-metre wireless communication range in open space provides substantial coverage for most residential properties and many small business premises. This range enables strategic placement of the alarm host in central locations while maintaining connection with perimeter sensors. The system's compatibility with regional variants (AU, EU, UK, US models) ensures appropriate power and communication standards compliance.\n\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"WiFi GSM household burglar alarm unit with wireless sensors for home security\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/495\/2025-10-02\/original-image\/1869910328010_f9fc888a-d303-41f8-a3f7-5dba7776a56e.webp\"\u003e\u003c\/div\u003e\n\nThis security system addresses multiple protection scenarios through its configurable design and wireless connectivity. The dual-network approach and telephone alert capabilities make it suitable for various security monitoring applications where immediate notification is valuable.\n\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\nThe system supports professional installation scenarios with its capacity for 100 configurable wireless devices across 100 defence areas. This extensive zoning capability allows security professionals to create detailed protection schemes for commercial spaces, storage facilities, or temporary event security. The 80dB alarm loudness provides sufficient audible warning in many commercial environments, while the telephone alert system enables remote monitoring by security personnel or property managers who may not be on-site during an incident.\n\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\nFor residential security, the system offers straightforward protection without complex wiring requirements. Homeowners can position wireless sensors at entry points, windows, or valuable asset locations while keeping the main unit in a discreet yet accessible position. The approximately 6-hour battery backup provides peace of mind during power outages that might coincide with security threats. The system's compatibility with China Mobile and China Unicom calling cards (as specified) makes it particularly suitable for regions where these networks dominate mobile communications.\n\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"WiFi GSM household burglar alarm unit with wireless sensors for home security\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/495\/2025-10-02\/original-image\/891710636439.webp\"\u003e\u003c\/div\u003e\n\nThis alarm system delivers practical security advantages through its combination of modern connectivity, wireless convenience, and configurable protection zones. The design prioritises functional reliability over aesthetic considerations, focusing on providing dependable intrusion detection and notification.\n\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\nThe wireless design reduces maintenance requirements associated with wired security systems, as there are no cables to degrade or become damaged. The backup battery system ensures continued operation during power interruptions, though users should periodically check battery status as part of routine maintenance. The system's capacity for 100 wireless devices allows for expansion or reconfiguration as security needs change, supporting reuse in different property layouts or for varying security priorities over time.\n\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\nThis alarm system offers distinct advantages for users seeking reliable security with modern communication capabilities. The dual-network approach through both WiFi and GSM provides redundancy that single-network systems lack, ensuring alerts reach you even if one network experiences issues. The 120-metre wireless range accommodates most residential properties and many commercial spaces without signal boosters or repeaters. The capacity for 100 defence zones allows detailed security planning, while the 80dB alarm provides both audible deterrence and occupant notification. For properties where telephone alerts are preferable to app-based notifications, this system delivers that specific communication method directly.\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"WiFi GSM household burglar alarm unit with wireless sensors for home security\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/495\/2025-10-02\/original-image\/90995776991.webp\"\u003e\u003c\/div\u003e","brand":"5mn5u0-4f","offers":[{"title":"ER G30 \/ UK","offer_id":57305782092158,"sku":"CJXFZNZN01853-ER G30-UK","price":111.98,"currency_code":"GBP","in_stock":true},{"title":"ER G30 \/ US","offer_id":57305782124926,"sku":"CJXFZNZN01853-ER G30-US","price":111.98,"currency_code":"GBP","in_stock":true},{"title":"ER G30 \/ EU","offer_id":57305782157694,"sku":"CJXFZNZN01853-ER G30-EU","price":111.98,"currency_code":"GBP","in_stock":true},{"title":"ER G30 \/ AU","offer_id":57305782190462,"sku":"CJXFZNZN01853-ER G30-AU","price":111.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/0150\/6942\/files\/1393643255048.webp?v=1777001599","url":"https:\/\/lindenmere.co.uk\/products\/household-burglar-alarm-with-wifi-and-gsm-dual-communication-supporting-telephone-alerts-80db-loud-alarm-120m-wireless-range-6-hour-battery-backup-configurable-for-up-to-100-wireless-devices-in-er-g30-style","provider":"Lindenmere.co.uk","version":"1.0","type":"link"}
