1. Tripod Turnstiles: The Compact Workhorse
The tripod turnstile, or three-roller turnstile, remains the most ubiquitous entry control solution globally. Its design features three rotating arms set at 120-degree intervals. When a user presents a valid credential, the mechanism unlocks, allowing a single 120-degree rotation.
Technical Performance and Specs
EIS Solution offers 9 distinct models of tripod turnstiles, including bridge-type and vertical standard options. Built with high-grade 304 stainless steel, these units are designed for longevity in harsh environments. With a typical passage width of 480mm and a throughput of 30 persons per minute, they are optimized for space efficiency.
Pros:
- Cost-Effectiveness: The lowest entry price point for automated access control.
- Compact Footprint: Ideal for narrow corridors or crowded entrances where every millimeter counts.
- Durability: Highly resistant to mechanical wear and tear; suitable for outdoor use with proper IP-rated enclosures.
Cons:
- Low Security Height: Because they are waist-high, determined intruders can jump over or crawl under the arms.
- Not ADA Compliant: The 480mm width is insufficient for wheelchairs, meaning they must be paired with a swing gate for accessibility.
Best Applications:
Tripod turnstiles are the “gold standard” for construction sites, public gyms, and budget-conscious transit hubs. Their mechanical simplicity makes them easy to maintain in high-dust environments like manufacturing plants.
2. Swing Barrier Gates: The Versatile All-Rounder
When discussing tripod turnstile vs swing gate options, the conversation usually centers on accessibility and aesthetics. The swing gate uses a motorized arm (or pair of arms) that swings open like a door.
Technical Performance and Specs
EIS offers 13 models of swing gates, featuring advanced brushless motors for smooth, silent operation. These gates are highly customizable, with passage widths ranging from 600mm to 1400mm. This makes them the primary solution for ADA (Americans with Disabilities Act) compliance.
Pros:
- Aesthetics: Often used in glass or acrylic, they offer a modern, “open” feel that matches high-end interior design.
- Versatility: Can handle wide passages for wheelchairs, strollers, and large deliveries.
- Bidirectional: Most models allow for flexible entry/exit configurations via software settings.
Cons:
- Throughput: Generally slower than flap barriers because the motor must swing a larger physical mass and ensure it is clear before closing.
- Footprint: Requires more “swing room” than a tripod or flap barrier.
Best Applications:
Swing gates are indispensable for corporate offices, hospitals, and schools where inclusive access is a legal or operational requirement. EIS also offers a specific children’s version for kindergartens and daycare centers.
3. Flap Barriers / Wing Gates: The Premium Choice
In the debate of flap barrier vs swing barrier, the flap barrier (often called a wing gate) wins on speed and precision. These gates utilize retractable “wings” that pull into the cabinet body to allow passage.
Technical Performance and Specs
The EIS wing gate series (6 models) is engineered for high-frequency use. They feature ultra-fast operation speeds (<0.2s open/close) and a throughput of 30–40 persons per minute. Advanced dual-sensor technology (IR + microwave) provides superior anti-tailgating detection.
Pros:
- Speed: The fastest opening mechanism among standard turnstiles.
- Security: The “flap” design makes it more difficult to crawl under compared to a swing arm.
- Safety: Equipped with multiple infrared sensors to prevent the gate from closing on a user (anti-pinch).
Cons:
- Cabinet Size: Flap barriers require thicker cabinets to house the retractable wing mechanism, requiring more floor space.
- Cost: Higher manufacturing precision leads to a higher price point than tripod systems.
Best Applications:
Ideal for banking centers, luxury hotel lobbies, and airport security checkpoints where a “no-touch” fast-pass experience is desired.
4. Speed Gates / Express Gates: The Ultra-Modern Option
A subset of the flap barrier, speed gates (or express gates) represent the pinnacle of lobby security. They combine a slim profile with high-speed movement and premium glass panels.
Technical Performance and Specs
EIS offers 6 models of express gates, including the popular AB style. These units are designed with high-torque DC brushless motors and can achieve throughputs exceeding 40 people per minute. Their slim profile allows for multiple lanes to be installed in narrow lobby areas.
Pros:
- High Aesthetics: Transparent glass panels give a sleek, futuristic look.
- Advanced Logic: Sophisticated algorithms detect tailgating and reverse-entry attempts with high accuracy.
- Space Efficiency: Thinner cabinets compared to traditional flap barriers.
Cons:
- Cost: This is typically the most expensive category of security gate.
Best Applications:
Tech companies, co-working spaces, and Grade-A office towers where the gate serves as both a security measure and a brand statement.
5. Full Height Turnstiles: Maximum Security
When physical prevention of unauthorized entry is the only priority, the full height turnstile is the undisputed king. Standing at 2.2m or higher, these are essentially revolving doors for security.
Technical Performance and Specs
EIS full height gates (3 models) are built for perimeter defense. They offer 90-degree or 120-degree rotation options. They are constructed from heavy-duty steel and are fully weather-resistant, making them suitable for 24/7 outdoor operation without a roof.
Pros:
- Anti-Climb: Impossible to jump over or crawl under.
- Unmanned Operation: The only gate type that can be safely left unattended in high-risk areas.
- Impact Resistant: Designed to withstand physical force.
Cons:
- Aesthetics: Often described as “prison-like”; not suitable for professional office lobbies.
- Low Throughput: Due to the size and weight of the rotor, passage is relatively slow (15–20 ppm).
Best Applications:
Correctional facilities, military bases, data center perimeters, and stadiums.
Decision Framework: A 5-Step Guide to Choosing Your Gate
Choosing between a tripod turnstile vs swing gate or a flap barrier vs swing barrier doesn’t have to be complex. Follow this framework:
Step 1: Define Your Security Level
- Low-Medium: Tripod Turnstiles (Deters, but doesn’t stop, a motivated intruder).
- Medium-High: Flap Barriers and Speed Gates (Detection sensors sound alarms for tailgating).
- Maximum: Full Height Turnstiles (Physical barrier to entry).
Step 2: Measure Your Available Space
Calculate the total width of your entrance. Remember that if you use tripod turnstiles or flap barriers, you must include at least one swing gate (minimum 900mm width) to satisfy ADA/accessibility requirements.
Step 3: Calculate Throughput Needs
Estimate the number of users during “peak hour” (e.g., 8:45 AM to 9:15 AM).
- Need 40+ ppm? Go with Speed Gates.
- Need 30 ppm on a budget? Go with Tripod Turnstiles.
Step 4: Consider Aesthetics and Environment
Is the gate indoors or outdoors? Tripod and full-height gates handle rain and dust better. Is it a luxury lobby? Acrylic or glass speed gates are necessary to maintain the building’s prestige.
Step 5: Budget Allocation
Balance the initial capital expenditure (CAPEX) with the long-term maintenance cost. While tripod turnstiles are cheaper upfront, the silent, brushless motors in premium swing and speed gates often have a longer mean time between failures (MTBF), reducing long-term operational costs.
