Physical Security That Actually Works.
From outdated analog cameras and physical keys to a fully integrated, cloud-managed security ecosystem — Charlie's Nerds designs, installs, and manages complete physical security systems for businesses of every size.
Cameras. Access control. Biometrics. Wireless locks. Environment sensors. One partner, one platform, fully managed.
Outdated Security Is No Security.
Most businesses are running security systems that were installed years ago and never updated. If any of these sound familiar, your business is more exposed than you think.
Your security cameras are years old — low resolution, no remote access, and impossible to manage
You still use physical keys that get copied, lost, or never returned when employees leave
You have no idea who is in your building, when they entered, or where they went
Your on-premise DVR/NVR system has failed or requires constant maintenance
A water leak, fire, or environmental issue went undetected until it caused serious damage
You cannot check your cameras or door access remotely from your phone
It's Time for a Security Upgrade.
Modern security systems are more capable, more affordable, and easier to manage than ever before. Let us assess your current setup and show you what's possible.

Whether you need cloud-managed cameras with AI analytics, a traditional on-premise NVR system, or a hybrid of both — we design and deploy camera systems that give you full visibility of your facility from anywhere.
We also specialize in upgrading outdated analog and early IP camera systems — assessing what can be reused and designing a modern replacement that delivers real security value.
Cloud-Managed IP Cameras
Modern IP cameras with full HD and 4K resolution, remote viewing from any device, cloud storage, and intelligent analytics — motion detection, person detection, license plate recognition, and more. No DVR to maintain.
On-Premise Systems
Prefer to keep footage on-site? We design and deploy on-premise NVR/DVR solutions with RAID storage, local redundancy, and optional cloud backup — giving you full control over your data.
Hybrid Cloud/On-Premise
The best of both worlds — local storage for speed and reliability with cloud access for remote viewing and off-site backup. Ideal for businesses with compliance requirements or bandwidth constraints.
Outdoor & Indoor Coverage
From parking lots and perimeter coverage to interior hallways, reception areas, and server rooms — we design camera placement for maximum coverage with minimum blind spots.
Video Analytics & AI
Modern cameras do more than record. We configure AI-powered analytics — occupancy monitoring, loitering detection, crowd alerts, and behavior analysis — turning your camera system into a proactive security tool.
Upgrading Outdated Systems
Still running analog cameras from 10 years ago? We assess your existing infrastructure, identify what can be reused, and design a modern upgrade path that maximizes your investment without tearing everything out.
Control Who Gets In. Know When They Do.
Physical keys are a liability. Lost keys, copied keys, unreturned keys — every one is a security risk. Modern access control eliminates that risk entirely while giving you complete visibility into building activity.
Cloud-Based Access Control
Manage every door in every location from a single cloud dashboard. Grant or revoke access instantly, view entry logs in real time, and receive alerts for unauthorized attempts — from your phone, anywhere.
Key Fob & Card Access
Replace physical keys with programmable credentials. When an employee leaves, their access is revoked in seconds — no rekeying locks, no chasing down key returns, no security risk from unreturned keys.
Biometric Access Control
Fingerprint and facial recognition readers for high-security areas where you need absolute certainty about who is entering. Credentials cannot be shared, copied, or forgotten — the person is the key.
Wireless Door Locks
Deploy access control without running wire through walls. Wireless smart locks from Assa Abloy, Yale, and Schlage retrofit onto existing doors with battery power — perfect for retrofits and interior spaces.
Multi-Site Access Management
One platform to manage access across all your locations. Centralize user management, set location-specific permissions, and see activity across your entire organization in a single view.
Guest & Visitor Tracking
Know exactly who is in your building and why. Digital visitor management captures guest identity, purpose of visit, host employee, and time in/out — replacing paper sign-in sheets with auditable digital records.
Elevator & Parking Control
Extend access control beyond doors — restrict elevator floors, control parking garage gates, and manage vehicle access. Ensure people can only reach the areas they are authorized to be in.
Time & Attendance Integration
Access control data can integrate with your HR and payroll systems — automatically tracking when employees arrive and leave for accurate time records without manual entry.
Detect Threats You Can't See.
Physical security is not just about people — it's about your entire environment. Our sensor solutions monitor for hazards that cameras and access control can't catch, giving you a complete picture of what's happening in your facility.
Vaping & Smoking Detection
Purpose-built sensors detect the chemical signatures of vaping and smoking in real time — triggering instant alerts to administrators. Critical for schools, healthcare facilities, offices, and hospitality venues where smoking is prohibited.
Water Leak Detection
Sensors placed under sinks, near HVAC units, around water heaters, and in server rooms detect moisture the moment a leak begins — before it becomes a flood. Get alerted instantly and act before thousands in damage occurs.
Smoke & Heat Detection
Intelligent smoke and heat sensors with faster detection and fewer false alarms than traditional smoke detectors. Integrated into your security platform so alerts reach you and your team immediately.
Air Quality Monitoring
Monitor CO2 levels, humidity, temperature, and particulate matter in real time. Poor air quality affects employee productivity and health — our sensors give you visibility and data to take action before problems escalate.
Temperature & Humidity
Protect server rooms, cold storage, medical supplies, and sensitive equipment with continuous temperature and humidity monitoring. Automated alerts when conditions go outside defined thresholds.
Door & Window Sensors
Know instantly when any door or window is opened or left ajar — after hours, in restricted areas, or during events. Integrate with your access control and camera systems for a complete picture of building activity.

Not sure which vendor is right for you?
We conduct a free site assessment and security consultation — reviewing your facility layout, existing infrastructure, compliance requirements, and budget — then recommend the right combination of vendors and products. We have no incentive to push one vendor over another; our recommendation is always based on what is best for your specific situation.

Most security companies install systems and disappear. Most IT companies do not touch physical security at all. Charlie's Nerds bridges that gap — giving you a single partner who designs, installs, integrates, and manages your complete security infrastructure.
We Design Before We Deploy
Every project starts with a site assessment. We map your facility, identify vulnerabilities, and design a system with zero blind spots before a single cable is run.
We Install Everything Ourselves
No subcontractors, no third parties. Our certified technicians handle the complete installation — from cable runs to camera mounting to software configuration.
Cloud or On-Premise, Your Choice
We work with both cloud-managed and on-premise systems and help you choose based on your specific requirements, budget, and compliance needs.
Integrated with Your IT Infrastructure
Physical security does not exist in isolation. We integrate your cameras and access control with your network, identity management, and alerting systems for a unified security posture.
Remote Management & Monitoring
View cameras, manage access, and receive alerts from anywhere. Your security system is as accessible as your email.
Ongoing Management Included
As part of our managed service, we keep your security systems updated, monitor for issues, and respond to alerts — so your physical security is as managed as your IT.
