Unveiling the Power of Lidar Technology

In today’s rapidly evolving tech landscape, security solutions are far beyond just locks, keys, and cameras. Advanced technologies are shaking up how we protect our spaces, and one such game-changer is Lidar technology. Originally developed for topographic mapping, Lidar has now found applications in various fields, including autonomous vehicles, archaeology, and significantly, in security. So, what exactly is Lidar, and how is it transforming the security industry?

What is Lidar Technology?

Lidar, short for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure distances. These light pulses, combined with other data recorded by the sensor, generate precise, three-dimensional information about the shape and surface characteristics of the target area. By emitting laser beams and measuring the time it takes for the light to bounce back, Lidar creates a detailed 3D map of the environment, which can be processed in real-time to detect movements, identify objects, and analyze patterns.

Safety Doesn’t Clock Out: After-Hours Protection

When the final bell rings, one might assume that school safety concerns end for the day. But for administrators, coaches, and community members, the reality is very different. Sports games, theater productions, and evening events bring unique challenges, and often fewer safeguards. If safety planning stops at the bell, schools leave critical gaps that can put students, staff and visitors at risk.

The Hidden Vulnerability

After-hours activities often involve multiple entry points, minimal staff supervision, and large crowds. Unlike the structured school day, these events can feel informal, which sometimes means safety protocols are relaxed. That’s a mistake.

As Jill Lemond, former school administrator and Evolv’s VP of Education, emphasized during a recent K-12 safety webinar, “we focus so much on the school day, but incidents can also happen during extracurriculars. Safety planning must extend beyond 8 to 3.”

A Simple Guide to Access Control Cards

In today’s security-conscious world, access control credentials play a vital role in protecting buildings, data, and personnel. Whether you’re securing an office, hospital, or industrial facility, choosing the right type of credential is essential for ensuring efficiency and security. In this blog, we’ll explore the different types of access control credentials and their unique benefits.

1. Proximity Cards (Prox Cards)

Proximity cards are one of the most common access control credentials used today. They operate using radio frequency identification (RFID) technology and allow users to gain access by simply holding the card near a reader.

Benefits:

• Contactless entry
• Durable and long-lasting
• Widely compatible with existing access control systems

Proper Maintenance Keeps Your Card Printer Running

Your ID card printer is a critical part of your identification workflow. Whether you’re issuing employee badges, school IDs, visitor passes, or secure credentials, a well-maintained printer delivers consistent, high-quality results, which is why printer maintenance is so important.

Printer Maintenance Should Be Part of Your Workflow

Every ID card printer, regardless of brand or model, has one thing in common: it’s a precision machine. When it’s clean and running optimally, it produces crisp, accurate cards with consistent color, sharp text, and strong adhesion. When neglected, you’ll likely encounter misfeeds, ribbon breaks, smudges, faded images, and eventually, costly repairs.

Common consequences of skipping maintenance include:

Streaky or incomplete prints
Damaged or worn-out printheads
Sensor malfunctions due to dust or residue buildup
Wasted cards, broken ribbons, and supply overuse
Security or compliance concerns from misprinted credentials

Whether you’re printing 10 cards a week or 10,000 per month, building printer maintenance into your routine protects your investment and reputation.
