Top 4 lighting factors that affect the performance and efficiency of perimeter security systems

When it comes to choosing lighting for outdoor perimeter security applications, there are four key factors that can mean the difference between identifying intruders and allowing them to get away scot-free: Color Rendering Index (CRI), lumens per Watt (lm/W), color temperature, and lamp life. 

The right combination of these factors can improve performance and add efficiency to security systems. So, what exactly are each of these factors?

1. Color Rendering Index (CRI)
A quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal (incandescent lamp) or natural light source (the sun). In essence, it describes illuminating an object to where the human eye or a camera is able to perceive all of the colors that make up the object, including the various shades of each color. The CRI scale ranges from 0 to 100; the higher the CRI value, the wider the spectrum of colors being emitted.

2. Lumens per Watt (lm/W)
The luminous efficiency of a lamp. The more efficiently a light can produce photons (light) from a given amount of electrical energy, the higher the resulting lumens per watt output. High lighting efficiency is important because it provides similar illumination using less power. From a perimeter security perspective, this means lower operational costs while maintaining a well lit perimeter to allow cameras to operate at optimal performance.

3. Color Temperature
The light appearance provided by a lamp. When a filament is heated to different temperatures, the type of light given off by different bulb is different. For example, soft white (emitted at lower temperatures) vs daylight (emitted at higher temperatures). For security applications, the closer to “Daylight” a light source is, the better since the captured image is more representative of its true colors.

4. Lamp Life
How long a bulb lasts before needing replacement.

Six steps to affordable perimeter protection and lighting

The Senstar LM100 is an affordable, easy-to-install system that enhances a security fence by turning it into a well-lit smart fence. A 2-in-1 system, the Senstar LM100 detects, locates and illuminates any attempt to cut, climb or otherwise break through a fence.  

This article explains the 6 basic steps required to protect a site: 

Step 1: Collect basic site requirements 

Survey the site and answer some basic questions related the site and requirements of your site. A great way to do this is to use an Internet-based mapping tool like Google Earth. It’s free and enables you to accurately measure perimeter distances. 

Key information includes: 

Step 2: Identify security issues and risks 

Next, walk along your perimeter and identify potential security risks.  

Make sure that the fence is in good condition and free from any loose, cut, or unsecured fabric. Also, check for any loose signage or vegetation that may move during high-winds and trigger nuisance alarms.

Finally, identify any outdoor equipment or cabling along the perimeter that may be susceptible to vandalism or tampering. 

Step 3: Determine your equipment requirements 

A Senstar LM100 system consists of the following equipment: 

Step 4: Install Senstar LM100 equipment 

Installation requires one person. Most perimeters can be done in a day.  

1.  Install the Gateway on or near the fence.
2. Install the Luminaire AP at the top of the fence near the Gateway.
3. Attach the luminaires to the fence along the perimeter.
4. Run 2-wire low-voltage cable along the fence to power each luminaire.  

Step 5: Configure and test for optimal performance 

To configure the system, simply attach a laptop computer to the Gateway with a standard USB cable and run the included software. You can: 

Step 6: Configure alarm outputs 

The Gateway’s built-in programmable I/O ports can be connected directly to the general-purpose inputs found on most alarm systems. The function of each I/O port is software‑configurable, including zone, supervision, tamper, and equipment issue alarms.

Save money while improving security

Is it possible to reduce both capital and operational costs while dramatically improving the perimeter security of a site? With the Senstar LM100 hybrid perimeter intrusion detection and intelligent lighting system, the answer is yes! Let’s compare the Total Cost of Ownership (TCO) of the Senstar LM100 against other security lighting solutions. The results are clear: The Senstar LM100 pays for itself in savings after period of 2–4 years. 

What is the Senstar LM100? 

The world’s first 2-in-1 perimeter intrusion detection and intelligent lighting system, the Senstar LM100 combines two key security functions in one cutting-edge product. The Senstar LM100 is a powerful deterrent – detecting and illuminating potential intruders at the fence line while alerting the site’s security system. 

How does it save money? 

With its ultra-efficient LED technology, simple installation, and long lifespan, the Senstar LM100 provides a Return on Investment (ROI) far exceeding that of traditional perimeter security lighting. By virtually eliminating maintenance costs and drastically reducing electricity usage, the Senstar LM100 has the lowest TCO of any perimeter security lighting solution. 

The following graph compares the 6-year TCO of current perimeter security lighting technologies. These costs take into account material, installation, operating, and maintenance costs over a 6-year period and are based on a 600 m (0.37 mi) fence perimeter. 

As the graph shows, the Senstar LM100 has a payback period of 2–4 years (depending on technology being replaced), with a 6-year maintenance and operating cost of only $620.
