5 year battery life nonsense.
5 year battery life nonsense.
Battery to Street Siren died after 2 years, no alarms, Uk temperatures, Ajax denied liability, 5 years life was a best scenario, load of rubbish. Not our problem sort it yourself.

Good afternoon!
We are sorry that the battery life of our sirens was the main reason for your negative review.
We would like to point out that the discharge of the supplied batteries may be due to several factors:
- The interval between device polls
- Ambient temperature
- Jeweller signal strength
- Frequency and duration of alarms
- Use of LED indicators
Actual battery performance may differ from the manufacturer’s specifications. Even batteries from the same batch may have different capacities, output voltages, or may be defective. That is why 100% of batteries are tested before being installed in Ajax devices.
We would also like to note that a flat battery does not indicate a fault with the device. This is a consumable item and can be replaced by the user. That is why our support team engineers have provided you with instructions on how to replace the batteries.
Ajax is a manufacturer of equipment and does not provide maintenance for systems installed on-site. If you need your batteries replaced, please contact your installer.
Kind regards, Max Brin

Exceptional support
Exceptional support at all hours of the day and night! I was having trouble configuring the app because my Belgian alarm company technician (nothing to do with Ajax) had given me the wrong instructions. I sent a message to Ajax support on a Friday evening around 7:45 PM Belgian time, hoping for a reply after the weekend. To my absolute surprise, I received a response within half an hour. Plus, there's a one-hour time difference with Ukraine (where Ajax is based). Our email conversation continued in impeccable French via a translator until 11:30 PM (12:30 AM their time) until I finally managed to configure the app correctly. Bravo to the Ajax support team, and long live Ukraine!

Outstanding Technical Support even on weekends
I am highly impressed with the Ajax Support Team. Not only did they respond to my technical inquiry on a Sunday, but the level of expertise was top-notch. They immediately understood the hardware diagnosis regarding the PSU capacitors and provided clear, professional guidance including official alternatives (12V PSU). This is how premium security support should look like. Fast, knowledgeable, and straight to the point. Special thanks to the team for the battery calibration tips. Five stars well deserved!

Easy to fit and operate
Easy to fit and operate. Only problem is lack of choice of the colour of the sensors. Had to pay another £40 each for the dark oak colour.

Ajax was recommended by my dad
Ajax was recommended by my dad. Also at my company we use it for securing assets. Really easy to install, setup and to use by yourself. Even my wife (who is a smart lady, but not so 'tech-savy') found it to be easy and usefull. Clear instructions. On top of that highly customizable settings for all connected devices. Two things to improve in my view are (1) the ai recognision system in the HL cameras often identifies birds and bugs as humans. Which makes it not viable to link alarms to human activity, and (2) the payment plan to get recordings from the doorbell is a bit disproportional. I appreciate ajax have to maintain servers (also for the rest of their free services), but it seems a bit skewed to put it all on the doorbell. I wouldn't mind paying one or two euros per month for all services to be kept up, but a jump from 0 to 25 just for cloud storage on one device feels extreme.
