Good post El B.
We looked at the system you described and found two big snags with it:
- It is reliant on the internet for remote operation (Grid down at the house or remote control location means no alert or control)
- The monthly subscription presumably means that the system can be disabled by the provider when THEY wish.
The system we chose is used to secure and monitor our remote retreat. It is 12v powered and is controllable over a landline telephone connection and or GSM mobile phone, so remains operational in grid down conditions.
Telephone / Mobile control allows us the following remote operations from anywhere in the world:
- Receive alert that alarm has gone off, including the trigger zone
- Remote Arm / Disarm
- Remote audio monitoring ( we can listen to hear if there is activity or fire in the property)
- Full talk through, allowing us to talk into the property via a loudspeaker ( warnings etc)
The system is 12v powered so runs off-grid from our 12v PV system. It supports 99 separate alarm zones, both wireless and hard wired.
We are very satisfied with both the ease of installation and also the effectiveness of the system, especially as it is independent of mains power. This type of alarm is widely available on the internet these days with simple systems costing less than £50! Only time will tell how effective they will be in the long term though.
