What Evolv Express actually does

Evolv Express is an AI weapons-screening system you put at an entry. People walk through at a normal pace without stopping, emptying pockets, or divesting bags, the whole difference from a walk-through metal detector. It uses low-frequency electromagnetic sensing combined with AI to look for the signature of firearms and large weapons specifically, and it's built to ignore the everyday metal people carry: phones, keys, wallets, belt buckles.

When the system flags someone, a guard sees it on a tablet, including where on the body to check, so secondary screening is fast and specific instead of a full pat-down of everyone in line. Because nobody divests, a single lane moves far more people per hour than a metal detector, which is why schools, stadiums, and hospital lobbies use it where a traditional checkpoint would create a line out the door. Lanes come in single or dual-lane configurations, current models are outdoor-capable with a weather rating, and the analytics layer rolls screening into dashboards: visitor flow, alarm statistics, and system performance over time.

A point worth being honest about: this is deliberately not trying to catch every small metal object. It's tuned to find guns and large weapons fast at volume. That's the right trade for a school or a venue and the wrong trade for a courthouse or a jail intake, and knowing which one you are is the first question we ask.

Where Evolv fits, and where it doesn't

We install across the major camera, access, and screening platforms, and Evolv is the screening layer at the entry. It's the right call on a meaningful set of deployments and the wrong call on others. Here's the honest read.

Where Evolv is the right call:

  • High-volume entries that cannot stop and pat down: A single Evolv lane moves people through far faster than a walk-through metal detector because nobody divests or empties pockets. For a school arrival rush, a stadium gate, or a hospital lobby, that throughput is the point. It keeps a real screening posture without turning the door into a 20-minute line.
  • Schools and houses of worship: The system is built to flag firearms and large knives while ignoring phones, keys, and wallets, so a school or a congregation gets a screening layer that doesn't treat every parent and student like an airport passenger. That experience matters for getting a community to accept screening at the door.
  • Venues and events with peak surges: Current Evolv Express models are outdoor-capable with a weather rating, and lanes come in single or dual configurations. For arenas, festivals, and event gates that surge hard at doors-open, stand up the lane count the crowd needs and pull it back after. The analytics show you visitor flow and alarm stats to right-size next time.
  • Security teams that want data, not just a door: The analytics layer rolls screening into dashboards: visitor flow, alarm statistics, and system performance over time. For a security director standardizing across multiple buildings or sites, that cross-site view turns screening from a guard's gut feel into something you can manage and report on.

Where Evolv is the wrong pick:

  • You need every blade and small metal item caught: Evolv is tuned to find firearms and large weapons fast at volume, and it deliberately ignores small everyday metal. If your threat model requires catching small knives, box cutters, or any metal object (a courthouse or a jail intake), a traditional walk-through or hand-wand posture is the honest answer, and we'll tell you that.
  • Very low-traffic single doors: The throughput advantage is the reason to buy this. A quiet office with a handful of badged employees walking in won't see the return a school or a stadium does. For a low-traffic door, access control plus a guard is usually the better spend, and we'll scope that instead.
  • You expect it to replace guards: Screening only works with a trained person resolving the flags and running secondary screening. The system points; a guard checks. With no staffing plan for the door, the lane becomes expensive furniture. We build the guard workflow into the deployment, because without it the technology doesn't do its job.

How Tec-Tel installs and tunes it

The hardware is a layer. The deployment is what decides whether screening protects the door or just slows it down, and that's the part we own. It starts with an entry walk at the times people arrive, because a lane in the wrong spot creates the bottleneck it was supposed to prevent. From there we plan the lane count per entry, place and power each lane, mount the tablet stations where the guard can see them, and, for outdoor gates, handle weather-rated placement and the network path so alerts and dashboards stay live during peak arrival.

Then comes the part that separates a screening posture from theater. We build the secondary-screening hand-off around your space so a flagged person gets resolved fast and the line keeps moving. We tune detection sensitivity against your real foot traffic and what people carry, so the system flags real threats and waves through laptops, water bottles, and umbrellas. Left at defaults, a lane either alarms on everything or gets dialed down until it misses; we tune deliberately for your venue. Finally we train your guards and front-desk staff on the lane, the tablet, the hand-off, and the analytics, and hand over a documented runbook plus a service standard in writing.

Realistic deployment timeline

A first-site rollout typically lands inside 3 to 6 weeks once the entry plan is set. The biggest variables are power and network at the entry and how many lanes your peak requires. If your entries already have power and a clean network path, you move fast; if a gate needs power pulled or weather-rated outdoor setup, that work sets the pace. Multi-site rollouts run as parallel waves so the calendar doesn't compound.

  1. Week 1: entry walk + flow read: We walk your entries at the times people actually arrive: where the crowd builds, how many doors are live during peak, where a guard stands, and where a secondary-screening table can go without choking the line. Output: a written plan of how many lanes per entry, single or dual lane, and where each one sits so screening doesn't become the bottleneck.
  2. Weeks 1 to 2: power, network, mounting: Each lane needs reliable power and a network path back to the analytics, plus tablet stands and, outdoors, weather-rated placement. We pull any power or cabling the plan calls for, mount the tablet stations where the guard can see them, and confirm the wireless or wired path so alerts and dashboards stay live during peak arrival.
  3. Weeks 2 to 3: stand up lanes + secondary screening: Lanes go in, tablets are paired, and the secondary-screening workflow gets built around your space. When the system flags a person, the guard sees where to check on a tablet. We set up that hand-off so a flagged person is resolved fast and the line keeps moving instead of backing up out the door.
  4. Weeks 3 to 5: tune sensitivity + cut false alarms: This is where the value gets earned. We tune detection sensitivity against your real foot traffic and what people carry (laptops, water bottles, binders, umbrellas) so the system flags real threats and waves through the everyday stuff. Left at defaults, a screening lane either alarms on everything or gets tuned down until it misses. We tune deliberately for your venue.
  5. Weeks 4 to 6: train guards + runbook: Your guards and front-desk staff are trained on the lane, the tablet, the secondary-screening hand-off, and the analytics dashboard. We deliver a documented runbook so the deployment doesn't depend on one person's memory, plus a written service standard for when something needs attention.

Running it alongside what you already have

Evolv is the checkpoint at the door, not a replacement for the rest of your security stack. Screening is strongest inside a layered posture: cameras watching the approach and the lobby, access control on interior doors, an intercom at the entry, and a way to push an alert when something happens. We design the entry so the screening lane, the cameras, and the access stack work together instead of as separate islands, and we route screening alerts to the people who need them. For the broader threat-prevention framing, see violence prevention and threat alerts; the front-entry check-in side is covered on visitor management.

What Tec-Tel adds vs going direct

Vendors sell the lane. Tec-Tel deploys it, which is what determines whether screening holds the door and whether your guards trust it. We own the entry-flow read, lane placement and power, tablet mounting, the secondary-screening workflow, sensitivity tuning to cut false alarms, the analytics connection, and guard training. We're a 15-year nationwide integrator, and one accountable project manager runs your deployment from the first call through every site, with Tec-Tel-managed crews held to one spec and one standard. One company, one invoice, clear accountability throughout.

We also bring multi-vendor honesty. If your threat model needs every small blade caught, we'll tell you a screening lane isn't the right tool and point you to the right posture. If a door is too low-traffic to earn it, we'll scope access control and a guard instead. And if you need screening, cameras, access control, and alerting together, we scope it as one job. The other install-side vendor guides are at vendor guides, and where screening fits by setting is covered on education security and houses of worship.

A note on partner-status language. Tec-Tel installs, integrates, and tunes Evolv Express. We don't claim a specific vendor partner certification on this page. If you need a vendor-certified deployment for a contractual reason, ask in the consultation and we'll confirm the credentials we hold or pair the install with a certified partner where required.
