Best Value Outdoor Sensor Available

Since 2003, VoiceAlert’s outdoor sensors have protected tens of thousands of homes across South Africa.  Feedback emails of gratitude indicate that hundreds of people literally owe  their lives to the early warning capabilities of this little marvel (triggering the VoiceAlert early warning base unit).  At the price, it is ‘criminal’ not to have it looking out for you!

Size Does Matter

In this case – small is beautiful.  The secret to VoiceAlert sensor’s phenomenal success as a crime barrier is it’s small inconspicuous size; battery driven and totally wireless (up to 300m range/100m through walls), you can mount this little wonder in areas criminals won’t think to look.

Triggers Voice, SMS, or standard Alarm/Siren/Armed Response

Voice Alert sensors are engineered to work with the USA-imported patented VoiceAlert System-6 wireless early warning panel.

However, they have proven to be such a reliable and affordable outdoor means of detection, that we have used them far and wide in all sorts of installations – wirelessly triggering out GSM/SMS and Standard Alarm panels.

Battery or Solar Powered

Powered by standard (square, matchbox-sized) PM9 batteries; available at any supermarket; depending on the amount of detection and transmission activity it experiences, VoiceAlert sensors can operate for months on a standard battery.  Alternatively, utilize rechargeable batteries (and our optional solar panel faceplate), or long-life batteries that will provide up to 5 times standard battery life expectancy (of several months).

When a low battery condition is detected, your VoiceAlert sensor will send a special code (for several weeks) – and the receiver will react by indicating via LED light, voice warning, or Sms precisely which zone has a low battery.

Easy to Configure

An 8-button dipcode array allows for up to 256 different frequency code selections – this allows up to 256 separate zone differentiations for any particular installation.  Any given dipcode array setting selected will allow the receiving base unit to define a particular zone, and react accordingly.

Easy to Mount

VoiceAlert sensors mount to any surface with two screws (for temporary installations; tape, Prestic, Velcro, or cable ties are often used – providing the base is stable and won’t shift in wind)  The ball and socket bracket allows the sensor to be orientated to face any desired field of view.

DIY Installation/Re-Location

Because of their simplicity, users can; having read the manual(!); place VoiceAlert wireless sensors wherever needed, and then re-position them as necessary – without fuss or need for technicians.

Unique Temporary Installations

Many of our clients (especially farmers, police/neighbourhood watches doing stakeouts, etc) utilize VoiceAlert sensors on a ‘floating’ basis, re-locating them regularly to ‘hot spots’.  We’re extremely happy to confirm that countless criminals have been caught ‘red-handed’ using our sensors.

Great RF/Wireless Range (to Base Unit)

VoiceAlert uses the highest (legislatively) allowed 433-mhz radio transmissions to trigger alarm panel base units (Signal repeaters/boosters and high-gain antennas are available from us on request).  The engineers quote “up to 300m line of sight, 100m through walls”.  But range depends on the terrain – we have seen ranges over 600m, but also under 50m (when a signal must travel at an angle through very thick walls).  In summary, VoiceAlert sensor RF range is truly the best we have seen out in the market.

Timing 0-seconds To 3-minutes

Each zone location requires a different performance; a timing screw that allows from zero to three minutes deactivation time on the sensor allows you to finely tune each sensor to a zone’s requirement.  E.g.  In a driveway; Where a lot of daytime trigger traffic might otherwise run a battery down (during certain times of day), yet a single trigger at night is all that is required, one might set the timing screw to the maximum 3-minute re-set interval. So – after a single trigger during the day, the sensor will turn off for 3-minutes and so not waste unnecessary battery trigger.  Conversely, up the side of a house where nobody every ventures, one would leave the default setting of ‘zero’ seconds for the sensor to re-set itself after a detection/transmission.  This means unit triggers, and immediately re-sets itself – and re-triggers/re-sets when it detects the intruder still loitering.

On/Off LED Switch

During setup and orientation of a sensor to cover a specific field-of-view, the built in LED displaying its red light through a prism window in the front of the sensor housing can be invaluable to provide an instant and aggravation-free indication when you enter that field-of-view.

However, in operation, it is generally an unnecessary waste of battery life.  More importantly, ‘stealth’ is one of the key’s to VoiceAlert’s sensors’ unique capabilities.  Because you can place VoiceAlert sensors in very unusual positions (under the eaves of roofs, in trees, etc. where most other sensors can’t be placed), allowing the light to illuminate when activated defeats the stealthy intent.  The LED On/Off switch allows you to deactivate the light, yet allows the sensor to operate with full function.
