Monitor your fence 24/7 from your mobile phone.

FenceAlarm can be used in any location with GSM coverage.

FenceAlarm is an electric fence monitor that alerts you immediately if the voltage drops which means you can act quickly and avoid the animals from escaping.

With FenceAlarm each farm saves on average 50 hours per year which makes it a good investment. But the best thing about FenceAlarm is that you can keep calm and be sure that the animals are kept in the pasture. FenceAlarm notifies you through an app (My.Luda.Farm) if the voltage in your fence would drop. With Alarm+ (optional), you will receive an alarm immediately in case the voltage drops in addition to a convenient voltage graph to help you determine whether the voltage drop is due to animals or shrubs/rain. FenceAlarm can be used everywhere where there is GSM coverage. The app is available for Android, Mac, IOS, and Windows. 3 year warranty.

If you want to buy a subscription to your SmartPlug / FarmCam Mobility or FenceAlarm, go to your account the app.

Why should I choose Luda.FenceAlarm?

Kristoffer at Kullingsjö agriculture in Vårgårda about his experiences:

Learn how easy it is to install and use Luda.FenceAlarm:

A chance to solve the problem before the animals escape

“I have tried a fence guard! A device that keeps track of the current on the animals’ fences. What a great sence of security! I’m often alone at home with three small children and worrying about animals escaping is really stressful! With “Smart Farming” you have an app in your phone that is connected to the product/products you have on your farm and you will receive notifications if something happens! If, for example, the power on our fence should drop you will get an alarm in the phone – how great is that? It gives me a chance to solve the problem before the animals escapes.

This is How it Works

1. FenceAlarm can be connected at any point on your existing fence. The unit can be powered for 2 months with the rechargeable battery, or it can be constantly supplied with 220 V or 12 V.

2. The voltage is measured by connecting the red fence clamp to the fence and the green ground clamp to the ground pin.

3. The voltage level of the fence is sent to My.Luda.Farm through the built-in SIM card, which always selects the operator with the strongest signal (i.e. operator-independent). You can check the fence status on your mobile whenever your want without having to physically visit the fence in the field to measure the voltage. Alarm+ warns you immediately if the fence voltage drops and it also gives you access to the handy Fence Voltage Graph™.

If the unit does not report for 24 hours or if the battery level becomes too low, you will automatically receive a notification from My.Luda.Farm on your mobile phone. There is no monthly fee for checking the most recently measured voltage (updated every 24 hours). *=For enhanced functionality, Alarm+ is available as described below. 12 month of Alarm+ is included in the price.

Get the App Here

You activate the Alarm+ by opening your My.Luda.Farm app, go to FenceAlarm and ALARM +, then click “Activate”.

  Voltage drop alarm

Alerts you and your colleagues in case the voltage of your fence would drop. Save time and money by instantly finding out if animals have broken the fence or if you have grass that draws power from your fencing.

  Fence Voltage Graph™
Through the voltage graph you see if the voltage drop is sudden (caused by animals) or slow (grass or rain). The graph helps you to make the right decision when you need to prioritize your time.

12 month of Alarm+ is included in the price. € 60/year (€ 5/month when choosing annual subscription) or € 10/month.

Question: How often does the fence guard check the fence voltage?
With Alarm , the unit checks the fence voltage once every minute when using a constant power supply or once every 10 minutes with battery power. Without Alarm , a voltage check of the fence is performed every 24 hours.

Question:  The GSM coverage where we have the animals is poor. Will the feature work anyway?
Answer: First check if you have mobile coverage at the location where you want to install the unit. If possible, try this with other mobile phones connected to different GSM operators. FenceAlarm automatically connects to the GSM operator with the strongest signal in your area (operator-independent).

Question: Can other people access my FenceAlarm?
Answer: Yes, using the My.Luda.Farm app you can decide which colleagues or family members you want to invite to your farm.

Question: Which units/electric fences does the FenceAlarm guard work with?
Answer: FenceAlarm is model independent and works with all existing unit/fence brands on the market.

Question: How long does the battery last and will I know if it becomes discharged?
Answer: The battery will last for at least 2 months. When the battery level falls below 10%, you will receive a notification from My.Luda.Farm on your mobile phone.

Fröstorp Farm in Sweden has taken a big leap into the concept of Smart Farming

– This summer, we bought several FenceAlarms to be able to get notified when one of the fences loses power. So far, we are very satisfied. It is very easy to get started. Just install the monitors, download the app and you are good to go. Whenever the power falls below a certain level, we receive alarms on our smart phones informing if the fences loses power. In this way, we can act quickly to prevent the animals from escaping. Because we have many animals on large fields, it is very time consuming to locate and bring back all the escaped animals. In addition to the time we save this way, it is also comforting to remain assured that the animals are where they are supposed to be when no notifications are received on our smart phones. Read More
