Comfort LED is available under the settings then general on the Yale App.

You can set the light to flash however this can drain battery life so instead of 12/18 months life span you may have 8/12 months with the light on.

The external siren is powered by four alkaline D batteries which have a life of 18-24 months on average.

The Yale Smart Alarms work on a very secure rolling code frequency of 868MHZ which offers a more stable connection and helps prevent anti jamming devices.

The Yale App will allow you to request images at anytime and not only when the alarm is triggered.

All components for the alarm systems are battery powered only. They do not have the facility to be wired into the mains electricity.

The Yale Smart Home Alarm Series has a built in rechargeable battery located in the hub and all contacts work with standard batteries so in the event of a power cut your alarm and its key features would be fully operational.

Accessories for each alarm kit cannot be swapped because the boxes are security sealed. You may prefer to order the Yale Smart Home Alarm Kit - SR-320 and add the Yale Easy Fit PIR Video Camera as an accessory when you add the alarm to the basket. Yale do not currently supply dual technology motion sensors.

Without an internet connection, this alarm will work as a standard alarm system. Triggering the alarm will activate the siren but you wouldn't receive notifications via the app.

The door sensors use V3 Lithium batteries. The PIR motion detectors and cameras take AA batteries. Both devices include batteries and they should be replaced every 18 months on average.

Yes, they can be used on most patio doors (this does depend on the door itself) please make sure that once the Door Contact is fitted there is no more than a 10mm gap between the contact and sensor.

No, the Smart Hub is not counted as one of the 20 components.

When the image camera is triggered it will alarm the siren and also send you an image through the Yale App.

You can purchase the alarm system now and ask for the install at a later date if required.

The viewing angle is 110 degrees horizontal.

As Standard the alarm would not arm, however you can 'Force Arm' the alarm by pressing the arm button a second consecutive time. You can also do this via the app but you would receive a warning notification to advise that the door was open.

The normal wireless range is 30 meters but this would be reduced slightly due to the thickness of the walls in your home.

The camera can capture an image or record a 10 second video. The images or video can then be viewed on your SmartPhone using the Yale Smart Home Alarm App and stored on the device the app is used on.

Unfortunately there is no constant record function or facility to connect the Yale Alarm Series to an NVR box. Once photos have been taken, they will be sent directly to your smartphone.

Without WiFi connection you will not receive pictures or notifications via the Yale App but the alarm siren would still sound when the alarm is triggered.

All the alarm systems are provided with one Active Siren Box only. These are not available to order as an additional accessory.

The alarm system is designed for internal use only, the sensors have not been tested for performance outside where they are exposed to the elements. We do offer a range of CCTV Kits which are suitable for outdoor use should you wish to consider these.

The camera provides a high quality 320 by 420 pixel image with a 15 meter range, including night vision.

The Yale SR-330 system does have a 30m wireless range. The Yale Sync Smart Home Alarm Family Kit Plus - IA-330 does have a 200m wireless range.

The sensors would have to be secured in place.

If there is a power and internet connection this should work. Please note this product has UK based warranty.

This alarm could be silent, if you do not use the external siren when operating the alarm. Providing the hub is connected to the internet router you would still receive an alarm activation notification to your mobile.

The alarm system will only allow 2 zones to be set, all sensors with in a zone must be either active or in-active.

Unfortunately, as of yet, it is only the PIR sensors that have the pet friendly functionality.

The Yale Easy Fit Keyfob is compatible with this alarm system.

The SR-330 alarm kit is the most recent model and includes Yale's new Smart Living branding and an upgraded Wi-Fi control box. The alarm is controlled by your SmartPhone with exactly the same features and accessories as the Yale Easy Fit SmartPhone Alarm which is being phased out.

Both sensors could be fitted within the room, though depending on access/coverage either sensor alone would be sufficient.
