Intelligent Video Security
Don't just record; understand. Our high-definition IP camera systems utilize AI analytics to detect threats proactively. Expertly designed by Door Security Group at our Manhattan headquarters and deployed through our nationwide partner network.
Quick Answers to Top Security Questions
We believe in clarity first. Here is everything you need to know about commercial surveillance before making a decision.
What Resolution Do I Need?
For general overview, 1080p is sufficient. However, for identifying faces, license plates, or cash transactions, we strongly recommend 4K (8MP) cameras for crisp zooming capability without pixelation.
Cloud vs. Local (NVR)?
NVR provides cost-effective, high-capacity local storage. Cloud offers remote accessibility and physical redundancy. Our experts often deploy hybrid systems for the best of both worlds.
Where Should Cameras Go?
Strategic placement is critical. Priority zones include all entry/exit points, points of sale, reception areas, exterior perimeters, and parking lots to ensure full, unobstructed coverage.
The Art & Science of Camera Placement
A camera is useless if it's pointing at the wrong angle or blinded by glare. At Door Security Group, our physical security experts map out precise field-of-view geometries to eliminate blind spots and secure your assets.
Choke Points
Focusing high-resolution cameras directly at eye-level near entrances to capture clear facial IDs of everyone entering.
Perimeter & Parking
Utilizing PTZ (Pan-Tilt-Zoom) and multi-sensor cameras to monitor large exterior areas and capture license plates effectively.
Beyond Recording: AI Analytics
Modern cameras do more than record video; they analyze the scene in real-time, turning passive recording into active threat prevention.
Intrusion Detection
Draw virtual tripwires. Get instant alerts if a person or vehicle crosses into restricted areas after hours, significantly reducing false alarms.
Facial Recognition
Identify VIPs or known offenders instantly as they approach your premises, integrating seamlessly with your broader access control systems.
Object Left Behind
Automatically flag suspicious packages left in public areas for extended periods, a crucial feature for high-traffic environments.

People Also Ask
Do I need cloud storage or a local NVR?
It depends on your IT infrastructure and security policy. A local NVR (Network Video Recorder) provides vast storage with no monthly fees and keeps data entirely on-site. Cloud storage (like Verkada) simplifies remote access, prevents data loss if hardware is destroyed, and pushes automatic firmware updates, but requires a strong internet connection. See our full cloud vs. local storage comparison for the full tradeoffs.
How do cameras perform in low light or nighttime?
Modern enterprise cameras use advanced infrared (IR) sensors and specialized low-light technology (like Axis Lightfinder) to capture clear video in near-total darkness. While standard IR provides crisp black-and-white footage, premium low-light sensors can maintain full-color video even in heavily shadowed environments.
Will IP cameras slow down my business network?
They shouldn't, if deployed correctly. Door Security Group engineers configure cameras to operate on a segregated VLAN (Virtual Local Area Network) or dedicated physical switches. Furthermore, modern cameras use H.265 compression, drastically reducing bandwidth and storage consumption compared to older formats.
Can you install cameras across multiple states?
Yes. While we are proudly based in Manhattan, Door Security Group manages a vetted nationwide partner network. We handle the system design, hardware procurement, and project management from our NY headquarters, ensuring standardized, high-quality physical security deployments wherever your facilities are located.
