ZEI engineers commercial network infrastructure that the rest of your facility depends on — structured cabling, managed switching, Wi-Fi 6E / 7, next-generation firewalls, and SD-WAN. Built for high-availability operation, segmented properly, and managed cleanly.
Technology Partners
A representative environment where ZEI engineers, deploys, and supports networking & wifi.
Where current systems fall short.
- Wi-Fi dead zones and roaming failures interrupting users and guests
- Flat networks where security cameras share a broadcast domain with payroll
- Outages caused by aged switches, untested failover, or single points of failure
- Slow, painful site-to-site VPN that does not survive carrier failover
- Networks no one understands because they were never documented
Robust Infrastructure
Your security and A/V systems are only as reliable as the network they run on. We build networks that never go down.
High-Density Wi-Fi
Wi-Fi 6/6E access points strategically deployed using predictive heatmapping to ensure seamless roaming and high capacity.
Next-Gen Firewalls
Advanced threat protection, deep packet inspection, and secure VPN access to protect your corporate data from external threats.
Cloud Networking
Manage your entire network stack—switches, routers, and APs—from a single cloud dashboard with deep analytics.
SD-WAN
Securely and efficiently connect multiple office locations with software-defined routing that prioritizes critical traffic.
What gets installed.
A real deployment is more than the headline product. These are the components we typically specify and integrate.
Structured cabling
BICSI-compliant Cat6, Cat6A, and OS2/OM4 fiber backbone with proper pathways, dressing, and labeling.
Core & access switching
Managed switches (Cisco, Meraki, Aruba, Juniper, UniFi) with proper VLAN segmentation, QoS, and PoE budget.
Wi-Fi access points
Wi-Fi 6 / 6E / 7 APs deployed via predictive site survey and verified by post-install heatmap.
Next-gen firewall
NGFW (Fortinet, Palo Alto, Meraki MX, SonicWall) with deep packet inspection, IDS/IPS, and SSL inspection.
SD-WAN / ZTNA
Software-defined WAN with carrier diversity, performance-based routing, and zero-trust remote access.
Network monitoring
Centralized monitoring of switches, APs, firewalls, and circuits with alerting on capacity and outages.
Power conditioning & UPS
Rack-level UPS with managed PDU so the network survives short outages without disruption.
Connects to what you already run.
Our networking & wifi integrate with your existing identity, communication, and security systems for unified operations.
How it gets built.
Every project follows the same engineering-led sequence — designed, documented, and delivered with no surprises.
- 01
Site survey & predictive design
Walk the building, capture floor plans, run predictive Wi-Fi modeling, and document existing pathways and equipment.
- 02
Architecture design
Logical network diagram, VLAN plan, IP addressing, QoS plan, and security policy documented before purchase.
- 03
Cabling install
Backbone fiber, horizontal Cat6/6A, IDF/MDF builds, and certified test results for every drop.
- 04
Equipment staging
Switches, APs, and firewalls pre-configured at our shop so on-site install is plug-and-play.
- 05
Cutover & validation
Phased cutover with rollback plan, post-install heatmap, throughput tests, and acceptance.
- 06
Documentation & handover
As-built drawings, IPAM, VLAN map, runbook, and admin training delivered as part of project close.
What our engineers look for.
- Predictive Wi-Fi site survey is done before AP placement is finalized — guesswork creates dead zones.
- Security devices, access control, and surveillance traffic live on dedicated, isolated VLANs.
- Cabling is engineered to a 10+ year service life: Cat6A or fiber for long runs, Cat6 for short runs only.
- Core, distribution, and access tier separation matches the building's physical layout, not vendor templates.
- Documentation (IPAM, VLAN map, port map, IDF/MDF photos) is a deliverable, not an afterthought.
After the install.
Service tiers built around what your facility actually needs — not a one-size-fits-all SLA.
Annual preventive review, firmware updates, and remote support during business hours.
24/7 remote monitoring of all network devices, 4-hour critical response, and quarterly capacity reviews.
Fully managed network operations including change management, security policy administration, and Wi-Fi optimization.
How the system fits together.

Bandwidth Calculator: How Much Do You Need?
Why Bandwidth Planning Matters The most common reason IP surveillance systems underperform has nothing to do with the cameras.
Designing the Network Backbone for a 500+ Camera Deployment
Designing a network for a handful of IP cameras is straightforward. Designing one for 500 or more is an entirely different discipline.
Fiber vs Copper ROI
One of the most consequential decisions in any low voltage project happens before a single cable is pulled: do you run copper or fiber?
Frequently asked.
Cloud-managed (Meraki / UniFi) or traditional (Cisco / Aruba)?
Wi-Fi 6E or Wi-Fi 7 — does it matter yet?
Can you take over an existing network?
How do you handle multi-site networks?
