Green LEDs mean your fence is strong enough. Red means it’s time to fix it. Simple as that.

Understanding the voltage levels
ZapSense shows the strength of your fence using 7 LEDs.
Here’s what each level means – and when you need to take action.
0 LEDs = below 500V (red)
Too weak – your fence is not working at all.
1 LED = 500–1000V (red)
Not enough to keep animals in out.
2 LEDs = 1000–2000V (red)
Still too weak – risk of escapes or intrusions.
3 LEDs = 2000–4000V (green)
Minimum level for a functional fence.
4 LEDs = 4000–6000V (green)
Strong and reliable for most animals.
5 LEDs = 6000–8000V (green)
Very good strength, suitable for horses, cattle, sheep.
6 LEDs = 8000–10000V (green)
High protection.
7 LEDs = above 10000V (green)
Maximum strength – excellent safety margin.
