Geovision 84-AS410-100 4-Door Access Control Panel

We've installed the 84-AS410-100 in retail, healthcare, and light-industrial settings for the past five years, and it's become our go-to four-door controller when the customer already has Geovision cameras in place. The real win is integration simplicity — there's no middleware, no middleware licensing headaches, and no credential sync delays. The panel talks natively to the Geovision NVR, so when an access denial event fires, the nearest camera automatically zooms or records at higher bitrate. On a 20-location retail chain, that unified policy management cuts your administrative overhead by 30-40% compared to running separate access-control and video vendors. That's money in the TCO column.

The LPR cable support is a secondary benefit that shows up strongly in retrofit projects. Most buildings wired in the last 10 years have LPR runs to at least a few entry points. Instead of trenching new Cat-5 or running shielded cable through existing conduit (painful), you repurpose what's there. The panel's power draw is modest enough that you can backpower the readers through the same cable without dedicated 24V runs, saving another 20-30 hours of labor per door.

Technical Highlights:

• Four Independent Relay Outputs: Each door gets its own relay contact — normally open or normally closed, configurable per-door. Fail-safe (strike unlocks on power loss) and fail-secure (strike locks on power loss) modes prevent credential creep on emergency evacuation or sudden power events.
• Wiegand Input Support: Accepts standard 26/34-bit Wiegand protocol from card and proximity readers. Credential validation happens locally on the panel (fast) with periodic sync to the central server (no latency on open/deny decisions). If the network drops, the last-known access list keeps the system operational for 24-48 hours.
• Multi-Reader Mixing: Each of the four doors can use a different reader type — one door uses magnetic stripe, another uses proximity cards, a third uses keypad. No firmware updates or controller swaps needed; the panel's input logic handles the variance.
• Event Logging Depth: Timestamps every credential read, access grant, access denial, door-forced (tamper), and lock-held event. Logs buffer locally for ~1,000 events if network is down, then flush to the central server when connectivity restores. Forensic-grade audit trail for compliance investigations.
• Door Hold and Alarm Outputs: Configurable timeout on door unlock — after 5 or 10 seconds, the relay de-energizes and the strike locks again. Prevents propped-door scenarios. If the door sensor shows the door open beyond timeout, the panel triggers an alarm relay (typically fed to a bell or siren) and logs a tamper event.
• Time-of-Day Access Rules: Credential access can be restricted to business hours, after-hours escort mode, or lockdown (no access). Rules are set on the central server and pushed to the panel; no on-site reconfiguration needed if you hire night-shift staff.

Deployment Considerations:

• Four doors is the hard limit on this unit. If you need to control 6 or 8 doors, you'll cascade two panels or upgrade to a larger Geovision controller. Plan your zone boundaries early — don't force a stairwell and a loading dock onto the same panel if they have different access policies.
• LPR cable has limitations: runs longer than 300 feet can experience voltage drop on the lock relay, especially if multiple readers are powered from the same cable. Confirm your existing LPR runs are up to the power load before spec'ing this panel into a retrofit; you may need to add 24V power injection midway through the run.
• Reader certification is important. The panel accepts standard Wiegand, but not all readers are equal. We've seen cheap proximity readers that emit noisy Wiegand signals and cause false denials. Stick to Geovision's certified reader list or test any third-party reader in your environment before commissioning. A simple test rig (panel + reader + laptop running Geovision test utility) costs $500 and saves weeks of field troubleshooting.
• Credential database residency: if you're migrating from a standalone access panel to this Geovision-integrated system, plan a cutover window. The panel can import from CSV or legacy card formats, but manual data validation is essential — an incorrectly imported access rule can lock out legitimate users or grant unauthorized access. Budget 4-6 hours for a 500-credential installation.
• Network redundancy: the panel caches the last access state, so a brief network outage (seconds to minutes) won't block doors. But if your Geovision server goes offline for hours, credential updates won't sync, and you lose visibility into access events until the network heals. If your facility is mission-critical, consider a second Geovision server or a failover appliance; this panel doesn't support multiple masters natively.
• Power supply: the panel itself draws ~3-5W, but the lock relays add 500mA to 1A depending on strike load. If you're powering four electric strikes from a single 24V supply, confirm you have at least 5A capacity. Undersized supplies cause relay chatter and erratic lock behavior — we've seen it field-diagnosed as a panel fault when the problem was a weak transformer.

The 84-AS410-100 is the right choice for integrators who already have Geovision video systems in place and need compact, reliable door control without adding a third-party access platform. It shines in multi-location deployments where you want unified credential and event reporting across video and access. For new-build greenfield projects with no existing Geovision infrastructure, compare carefully against standalone access platforms like Salto, HID, or Honeywell Maxpro — they may offer richer analytics and mobile credential support. But in retrofit scenarios and tightly integrated video+access deployments, this panel earns its place. For more options, visit the Geovision catalog.
