Farms WithOUT Signal

For those with limited cellular reception on their farm

Our base station system lets you monitor livestock and detect unusual activity across your property, even in remote areas with limited or no cellular reception.

Alerts and insights are delivered straight to your phone via the Agri-Alert mobile app, keeping you connected to what matters most on your farm.

A Farm Security Ecosystem Built for Environments with limited cellular reception

Base Station

The link between you and your sensors

The base station is the only part of the system that needs to be within range of cellular reception. It is the channel through which you gain access to your out-of-coverage assets and animals.

Once installed, the base station provides a 2 kilometre radio coverage radius to communicate with all your sensors, enabling you to monitor assets and livestock where cellular reception is limited or non-existent.

Equipped with a solar panel, the base station operates 100% independently and includes all necessary equipment to receive sensor alarms and transmit them to the Agri-Alert app on your phone. 

Sensors

Your sensors communicate with the base station via radio signals – no cellular reception needed. 

For complete farm security, customise your sensor combination: activity collars for herd or flock monitoring, GPS collars for key animal location tracking, movement and tilt sensors for gates and storage, and temperature sensors for chicken coops, grain stores or cold rooms.

Livestock Collar sensors

Collar with Activity Sensor

  • Activity collars monitor animal group behaviour (movement patterns and activity levels) and trigger alarms when activity deviates from the animal’s normal behaviour.
  • Abnormally high or low activity instantly alerts you via the Agri-Alert app on your smartphone.

Collar with Activity and GPS Sensors

  • GPS collars offer all the features of activity collars, plus precise location tracking within 5m, custom virtual boundaries (geo-fences), and instant notifications when animals stray beyond designated zones.
  • Receive separate alerts for concerning activity and geo-fence breaches, so you know exactly what’s happening and where.

Other Sensors

Tilt Sensor 

Alerts you instantly when solar panels, gates, barn doors, or implement bonnets are tilted or opened.

Movement Sensor

Triggers an alert whenever the monitored asset moves. Ideal for securing stationary items like seed bags or barn windows.

Temperature Sensor 

Monitors environmental temperature in chicken coops, grain storage or cold rooms and alert you to preset temperature breaches.

Your Farm Security ecosystem, Connected in One App

The Agri-Alert app is your farm security control hub, centralising all alerts and data from the base station.

Receive Real-Time Security Alerts

Instant notifications keep you connected to your farm. Alerts cover abnormal animal behaviour, geo-fence breaches, and asset security threats.

Full Herd Visibility

View livestock’s locations on an interactive map and track movement patterns over time.

Precision Zone & Herd Management

Create geo-fences (zones) and customise your collar sensor settings to match your farm’s needs.

Monitor Collar Health in Real-Time

Monitor battery levels and connection status for each collar. Instant alerts keep your herd protected.

Why use our base station system on your farm?

Real-Time Mobile Alerts for In-Time Response

The Agri-Alert app informs you of security threats like abnormal behaviour, zone violations, or asset movement immediately.

Livestock can roam outside cellular reception

Thanks to the base station, you gain access to livestock that roam in zones outside cellular reception, ensuring you never stop monitoring your livelihood.

A Cost-Effective, Scalable Solution

Our base station system approach lowers the cost-per-collar, making the system much more scalable. Farmers can afford to add multiple collars to a single herd or flock, monitoring the movement and status of the whole group of animals, as opposed to just one. Monitoring a group expands your data profile and reduces false alarms and the associated risks.

Analyse long-term behavioural trends and grazing patterns

View GPS collar locations and analyse movement patterns to determine long-term behavioural trends, make informed decisions about herd dynamics and determine which sectors of your farm animals prefer or avoid for grazing.

Hardware Warranties and Updates

Collars carry a full two-year warranty, with devices replaced free of charge at the end of two years, ensuring farmers always have current technology.

Frequently Asked Questions

The base station is installed on a tower 10-12 meters high, which the farmer must provide and erect. Agri-Alert provides installation guidance to ensure optimal placement and setup. Base station installation is straightforward: orient the solar panel north, ensure all components are securely fastened, and neatly attach the aerial wire. Installation requires only the basic skills of fastening two U-bolts.

Sensors and collars communicate with the base station via radio signals – no cellular reception is required. The base station then uses the cellular network to transmit alarms to the farmer. All base stations are capable and designed for 2G, 3G and 4G connectivity.

During the initial calibration process, we establish a baseline by monitoring the herd's movement patterns over 4 days.  We use this baseline data to calibrate collars to your herd's unique patterns.  However, the system also continuously learns from the collars’ real-time sensor data transmitted to the base station, refining the behavioural profile over time and adapting to seasonal changes in animal movement. When the herd's activity deviates from the established baseline, the system triggers an alarm. 


Activity collars monitor herd behaviour and generate alarms when activity deviates from established baselines. GPS collars offer all the features of activity collars, plus the ability to determine the animal's position within 5m, set geo-fences, and map movement patterns. While GPS collars command a premium over activity-only models, the additional investment is justified by enhanced location precision and movement-mapping capabilities. 

For farms exceeding the base station's range, relay stations can extend radio network coverage to additional zones.  Each relay station can cover another 1,250 hectares. Our team conducts a comprehensive signal coverage analysis of each farm to determine optimal base station placement and height, ensuring maximum radio coverage and system reliability.

The base station has multiple fail-safes built in. A motion sensor triggers an alarm immediately if the unit is removed from the tower, protecting against theft. The integrated battery provides four days of backup power, even in low-light conditions, ensuring continued operation during extended cloudy periods. Additionally, the system continuously monitors battery levels and alerts the farmer if power reserves fall below safe thresholds. If the base station goes offline for any reason, you’ll receive an immediate notification. This multi-layered approach ensures you are never caught unaware of system issues.
