Alltech Security is distributor and installers of perimeter security lights in Kenya which are perfect for Perfect for:
 Fence and security lines
 Gate or entry points
 Wall and perimeter areas
Sol’s solar and energy saving grid-tie LED lighting is the ideal solution for perimeter and fence lighting. Whether to detect and recognize possible intruders, or for overall site/building illumination, Sol has you covered for increased security and safety. Protecting facilities, people and assets is increasingly important.

Alltech Kenya perimeter security lights are on-grid LED lights are ideal when retrofitting to lower monthly energy and maintenance costs. Fences, walls and borders are often a long distance from established electrical and communications equipment.

Wireless lighting is often the most cost-effective way to illuminate perimeters, especially for new installations. Configured for full light intensity throughout the night or set with motion sensors, solar perimeter security lighting is SUPERIOR to on-grid lighting since there are no wires to cut and tampering with one light will NEVER impact other lighting systems.

Perimeter Intrusion Detection Systems

Perimeter Intrusion Detection Systems (PIDS) are systems used in an external environment to detect the presence of an intruder attempting to breach a perimeter. The adoption of fiber optic Distributed Acoustic Sensing (DAS) technology is growing rapidly as part of PIDS strategies for a number of companies across a range of industries.

The Four Main Types Of Perimeter Intrusion Detection Systems

Barrier-Mounted – Fence Intrusion Detection System

PIDS deployed on or in conjunction with a fence or other physical barrier (e.g. DAS cable or other motion sensors mounted on a fence).

Ground-based or Below-ground

PIDS deployed below ground (again a DAS cable can be used or pressure sensitive cable or electromagnetic field). These do not require a physical barrier.


PIDS deployed above ground that do not need to be installed on or in conjunction with a physical barrier (e.g. bistatic microwave link).

Rapidly Deployable

PIDS that are designed for temporary deployment; for example, to protect a mobile asset. Typically this would cover military applications and again DAS sensing technology has been very successfully deployed in these environments.

Perimeter Security Solutions Selection Guide

When deciding on the specification and selection of any PIDS system the following factors must be taken into consideration:

  • Landscape, flora, fauna and topographical features
  • Integration with other types of equipment or systems
  • Climatic conditions
  • Local regulations
  • Presence (or lack of) physical barrier and robustness against threats
  • Duration of required deployment (rapidly deployable PIDS)
  • Response force arrangements
  • Personnel on site

All of these factors will affect the key choices made by an organisation and there are also other-point to consider including:

  • Whether a line of site technology is appropriate (e.g. radio wave based technology or camera based systems). For instance, are there any undulations in the ground surface? Undulations occurring over the distance of a metre andup to several tens of metres can shield the presence of an intruder from some detection technologies, particularly in the case of microwave systems, visual cameras andactive or passive infrared.
  • Does the detection system needs to be covert (buried or hidden)?
  • Are there specific electromagnetic interference issues that will affect specific technologies or are there requirements for the technology to be intrinsically safe (e.g on oil rigs or process plants)?
  • Is there existing infrastructure to mount the system or whether it will be part of a new build?
  • How does the system integrate with the overall security strategy.?What constitutes an alarm and what action is taken in the event of an alarm (audio alarm, visual alarm or a combination)?

In some scenarios, particularly where perimeters are large or the asset is critical, the asset owner may choose to use multiple technologies and integrate the respective monitoring systems through a centralized control system (e.g. Video cameras combined with DAS, where the cameras slew to the specific event when an alert is raised.)

Perimeter Intrusion Detection System using Distributed Acoustic Sensing

Distributed Acoustic Sensing systems can monitor the acoustic signals along the length of the fiber optic cable and are able to classify the acoustic signatures and pinpoint the location of an intrusion event to typically within 5 m.

The distributed acoustic sensing system consists of an interrogation unit with the relevant optoelectronic components (laser source(s), detectors and associated processing hardware, firmware and software) to monitor a length of optical fiber cable which can be run outside, on and inside the perimeter. These DAS systems have different distance capabilities ranging from 5 km to 100 km. The examples below show how a single system can be configured to monitor inside, outside and on the perimeter itself.
