Ensure Unfailing Alarm Delivery with the AJAX VHF Bridge
Introducing the AJAX VHF Bridge, a crucial transponder that provides your Ajax security system with an additional, ultra-reliable channel to communicate with a monitoring station. Designed for ultimate resilience, this module allows you to use Ajax systems in locations with unstable or non-existent internet connections, such as nature reserves, mountainous regions, or remote properties. By transmitting alarms and system events over VHF radio waves across vast distances, the vhfBridge ensures your security is never compromised, serving as either a primary or a backup communication link.
Core Features & Benefits
- Internet-Free Alarm Transmission: Guarantees that alarms are sent to the central monitoring station via VHF radio waves, completely independent of an internet connection.
- Universal Compatibility: Seamlessly integrates with any third-party VHF transmitter that has relay inputs, offering you flexibility and choice.
- Proprietary Jeweller Radio Technology: Leverages Ajax's secure, two-way communication protocol. It features block encryption, protection against spoofing, and frequency hopping to prevent jamming, ensuring all data is secure.
- Extended Communication Range: Achieves a remarkable radio communication range of up to 1,800 meters (5,900 ft) in open space between the module and the Ajax hub or a range extender.
- Impressive Power Autonomy: In the event of a power outage, an optional 7 Ah backup battery (not included) can power both the vhfBridge and the connected VHF transmitter for up to 75 hours.
- Advanced Anti-Sabotage: The device is equipped with two tampers that provide instant notification of any attempt to open the casing or detach it from the surface.
- Effortless Configuration: All 8 transistor outputs are easily configured through the user-friendly Ajax mobile and desktop apps, allowing you to specify exactly which events trigger an alarm.

You won't regret buying these pillows, they're absolutely perfect.
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
I absolutely love these pillows, I love the fact that they come with a cover to protect them. They're just the right amount of density to them to make them extremely comfortable. They don't flatten down and just stay flat. I've had one set of them for quite a while now and they're still just as good as the brand new ones that I bought. Eventually I will be replacing every pillow in my house with these pillows. They're very well made, The filling is just right, the size is perfect, the quality is absolutely amazing. If you buy these pillows you won't regret it, they're literally the probably the best pillows I've ever bought. And also one of the cheaper ones that I bought in price not quality. And I've never bought any of the store that come with the protective covers with them either. I do highly recommend them.

Would buy again
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
I bought these pillows with the pillow protectors included. After 15 minutes of fluffing the pillows in the dryer they took their shape and were ready to use.

Nice medium thickness. Fits in shames great. Firm for a medium but will work well
Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
Nice pillows for the price. I got the medium thickness and itβs a little stiff, but I think once slept on, it should soften up a bit, but if you like a softer or flatter pillow, definitely go for the soft one. But the quality seems to be very well-made. It puffed up straight out of the package. It didnβt have any smell whatsoever, and it fit perfectly in my standard size shams.
