What is the Ultra-Safe system and how does it work?

The Ultra-Safe is a stand-alone, wireless Do-It-Yourself early warning perimeter alarm system.

It uses one or more battery-powered outdoor detectors (called ‘Sentinels’) and a portable base station that is located inside your home. The base station sounds an alert tone if an intruder is detected outside.

If an intruder approaches your property, the Sentinel sends message to the base station. The base station sounds an alert tone that provides you with an early warning that an intruder is on your property.

Unlike older technology outdoor sensors, the Ultra-Safe will not be triggered by animals, wind, and leaves (provided the simple installation guidelines are followed) so you can sleep safe and sound knowing that you’ll only be alerted if an intruder is approaching.

An Alert Tone?… What good is that?

It’s very good.

You have taken away the intruders best weapon….

….the element of SURPRISE!

You know he is on your property

You know where he is – the base station has a different alert tone for each Sentinel

You’re inside, awake, alert and able to assess the danger and make an appropriate response.

When an intruder triggers the 15-metre invisible ‘trip-wire’ an alert tone is played by the portable receiver. You can easily set which tone you would like to hear when the system is triggered – there are 4 to choose from. You can add up to 4 sensor units and have each one play a different tone so you can tell immediately which beam has been tripped. The sensor can be mounted up to 500 metres from the receiving unit (see my notes below regarding range)

The receiving unit has a volume control and an on/off switch so you can turn the unit off when you’re expecting visitors. You can also move the receiving unit from room to room – it could be in the kitchen, living room or office during the day and moved to the bedroom at night.

The receiving unit can also be connected to any new or existing alarm system to create a really powerful deterrent to potential intruders. Imagine an intruder crossing the ‘trip-wire’ and being blinded by several high-intensity flood-lights, being blasted by ear-shattering sirens and even soaked by your automatic sprinkler system! Breaking into your home suddenly doesn’t seem like such a good idea!

It’s all possible with the Ultra-Safe Home Guard and a bit of imagination.
