Lock Down Mode

The moment that Ultion detects forced entry it activates an attack lock directly into the central cam, this is ‘Lockdown Mode’.

Even if the most determined intruder gets past Ultion’s two sacrificial sections he won’t get to the attack lock because it is protected deep inside a solid molybdenum core and secured with a dedicated retaining pin. When Ultion is in Lockdown Mode your home and family are safe.
