Security solutions
Perimeter & physical security
The first layer of security is the physical environment — designed so that a site is difficult to enter unnoticed and easy to control once it is busy.
Securing the edge before the building
Most security incidents begin at the boundary. A perimeter that is easy to cross, poorly lit or unwatched turns every internal control into the only control. Perimeter and physical security is therefore about shaping how people and vehicles approach, where they can go and what happens when they try to go somewhere they should not.
Logitech Consultants plans perimeter protection as an integrated layer rather than a list of equipment. Fencing and detection define the boundary, gates and turnstiles define the crossing points, lighting and CCTV make those crossings observable, and alarms bring the right person to the right place. Each element is specified for the site's actual configuration, operating hours and risk profile.
What perimeter protection covers
-
01
Electric fencing
Perimeter fencing with energised wires as a deterrent and detection medium, zoned and monitored so that a triggered section can be located rather than merely announced.
-
02
Perimeter intrusion detection
Detection technologies for fence lines, walls and open ground, selected with the site's vegetation, wildlife, weather and false-alarm tolerance in mind.
-
03
Security gates and pedestrian gates
Vehicle and pedestrian gates that control the crossing point itself, with operating methods matched to the traffic volume and the level of supervision available.
-
04
Turnstiles
Pedestrian control for staff entrances, production areas, stadia and public buildings, integrated with access credentials so that each passage is recorded.
-
05
Rising arm and hydraulic barriers
Vehicle barriers for entrances and car parks, including faster hydraulic units for high-traffic points and longer arms for wider carriageways.
-
06
Bollards, road blockers and spike barriers
Hostile-vehicle mitigation and controlled access for critical areas, detailed further in the vehicle-control section of our portfolio.
-
07
Security lighting
Lighting designed with the cameras rather than after them, so that illumination supports identification at the points that matter and does not create glare for operators.
-
08
Intercom and video door entry
Entry points that are not permanently staffed, connected to a reception or control room for verification before release.
-
09
Perimeter CCTV and alarm integration
Camera coverage aligned to the fence line, gates and yards, with alarms and detection events bringing the relevant view to the operator automatically.
How the perimeter is planned
Assessing the boundary as it really is
A perimeter survey records the length and condition of the existing fence, wall or hedge, the ground on either side, vegetation, drainage, public footpaths, neighbouring activity and the points where vehicles and people legitimately cross. Risks that are theoretical on a drawing are often obvious on site — a gap behind a store, a gate left open for deliveries, a blind corner at shift change.
- Boundary length and construction recorded by zone
- Approach routes, public access and neighbouring land use reviewed
- Existing gates, barriers and lighting assessed for reuse
- Operating hours and shift patterns confirmed with the site team
Detection that people will keep switched on
Perimeter detection is only useful if the site trusts it. A system that alarms on every passing animal or swaying branch is disabled within weeks. We select and position detection for the environment, tune sensitivity against real conditions, and where necessary combine technologies so that an alert carries more than one signal.
Layers that reinforce each other
The perimeter is the outer layer of a wider system. We connect gates, turnstiles, barriers, detection, lighting, CCTV and alarms to access control and command-and-control software, so that a forced gate or a triggered fence zone produces a coordinated response: the camera view opens, the alarm is logged and the operator knows which section to investigate.
Implementation and support
Perimeter works affect the boundary of a live site, so sequencing and reinstatement matter as much as the equipment.
- Works phased by zone so that a section of perimeter is never left open or unmonitored overnight.
- Civil and electrical works coordinated with existing walls, gates, cabling and site drainage.
- Commissioning that walks every detection zone and gate under normal and adverse conditions before handover.
- Guard and operator training on alarm response, gate procedures and escalation.
- Preventive maintenance covering fence energisers, detection alignment, gate mechanisms, hinges, locks and lighting.
Questions we are asked
Do we need electric fencing if we already have a wall?
Not always. A wall provides delay and deterrence; detection tells you when someone is attempting to cross it. The right combination depends on the wall's condition and height, what is behind it, how quickly a response is possible and the consequences of an intrusion. We assess the boundary and recommend the minimum that gives dependable warning.
How do we avoid constant false alarms?
By matching the detection technology to the environment and tuning it on site rather than on a datasheet. Vegetation clearance, zone design, animal activity and weather all affect performance, and we test under real conditions before handover. Where a single technology is unreliable, we combine signals so an alarm requires corroboration.
Can new gates and barriers be added to our existing access control?
Usually, provided the existing controller supports additional readers, inputs and outputs, or can be extended. We review the installed system and its remaining service life, then propose integration where it is sound and replacement where extending it would create a weak point.
What maintenance does a perimeter system need?
Fence energisers and detection need periodic testing and vegetation clearance; gates and barriers need mechanical servicing, hinge and lock checks and safety-device testing; lighting needs cleaning and lamp or driver replacement. A maintenance agreement sets intervals and response times so these are scheduled rather than reactive.
Can the perimeter be monitored off site?
Yes, where the network and your security policy permit it. Remote monitoring is configured with authenticated access, restricted permissions and an audit trail, and is designed so that the site continues to function locally if the connection is lost.
