Barriers / Gates / Bollards

Ask a question

Sigur can control any barrier devices, including barrier arms, gates, bollards and roller shutters.


Gates, barrier arms, bollards and roller shutters are devices designed to limit access to a territory. Every type has its own purposes, advantages and limitations, and therefore the choice of devices depends on what problems you are trying to solve.

To ensure enhanced security, these devices can be installed in combinations (i.e., bollards can be used together with barrier arms or gates).


To control gates, barrier arms, bollards and roller shutters, Sigur sends certain commands to the devices:

  • Start the opening movement
  • Start the closing movement
  • Stop the movement

You can control these devices from Sigur software or from the security control panel.

Sigur controllers can also control devices with or without their own control units.

In Sigur, the user can manually customize a large number of parameters allowing for more flexible device operation. For more details, please see the manuals.

In Sigur, barrier devices are operated by controllers directly and therefore they will work even if the server is not available.

Access rules and policies

To ensure maximum flexibility a number of access rules and policies can be assigned to:

  • Different checkpoints / groups of checkpoints
  • Different employees / groups of employees
  • Different movement directions (entry and/or exit)


To ensure correct and faultless operation of gates, automatic arms and other barrier devices, you will need some essential components to be connected to the controllers (you can also add some optional components):

  • One centralized reader or two readers (one on each side of the gate) or all three of them
  • One central sensor
  • Two car proximity sensors on both sides of the gate
  • Motors or a controller to operate gates or barrier arms
  • Remote control (optional)
  • Additional equipment such as traffic lights or displays (optional)


In total, one or three sensors can be connected to a Sigur controller, such as an induction loop or photoelectric sensors.

Generally, they are installed as follows: one is installed on the gate line to prevent the gate (barrier arm) from accidentally closing (dropping) on the still moving car and two other sensors are installed in front of the gate on both sides to determine the direction of movement.

Output terminals of several sensors can be connected in line to a single controller port. In this case, you can install several photoelectric sensors on the gate line at different levels or different distances from the gate to ensure greater control over the movement of a vehicle and safer operation.


A standard scheme of two readers (one for incoming and one for outgoing vehicles) can be used. Any types of readers can be installed, including regular contactless card readers, long-range readers, RFID tag and key fob readers.

Sigur supports one-reader configurations. In this case, the direction of movement is determined based on the data from the vehicle presence control sensors located at both sides of the gate. With this feature, your visitors will be able to use RFID key fobs and a single receiver will receive the signal from the key fobs.

If a video surveillance system with number plate recognition functionality is installed at your site, you will be able to use vehicle number plates as identifiers.


With the remote control, you can operate gates and barriers manually. Sigur records all events in the archive to help control the guard’s actions, including manual device operation.


For organization of the automated flow of vehicles at sites with active vehicle traffic, such as at warehouses or freight companies, factories, car parks, etc., you might want to install additional control devices, such as traffic lights.

Sigur controllers can operate traffic lights, LED signs and information displays.
