What is a Video Surveillance Security System?
A video surveillance security system is an integrated solution that combines multiple components to provide comprehensive visual monitoring and recording of your property. Unlike standalone security cameras, a complete video surveillance security system includes:
- Security cameras (indoor/outdoor, various types)
- Recording device (NVR for IP cameras, DVR for analog)
- Storage (hard drives, cloud, or hybrid)
- Monitoring software (desktop and mobile apps)
- Network infrastructure (switches, cabling, PoE)
- Integration capabilities (alarm systems, access control)
The key difference between a video surveillance security system and individual cameras is centralized management and integration. A properly designed system allows you to:
- View all cameras from a single interface
- Search and export recorded footage quickly
- Receive intelligent alerts based on motion, sound, or AI detection
- Integrate with existing alarm and access control systems
- Scale easily as your needs grow
Types of Video Surveillance Security Systems
IP Camera Systems (Network-Based)
IP (Internet Protocol) camera systems transmit digital video over your network. They represent the current standard for professional video surveillance security system installations.
Advantages
- + High resolution (up to 4K/8MP)
- + AI analytics capabilities
- + Power over Ethernet (single cable)
- + Remote configuration
- + Easy scaling
- + Better image quality
Considerations
- - Higher initial cost
- - Requires network infrastructure
- - More complex setup
- - Cybersecurity considerations
- - More storage requirements
Best for: New installations, businesses, properties requiring analytics, remote monitoring
Analog CCTV Systems (Coaxial-Based)
Traditional CCTV systems use coaxial cable to transmit video signals to a DVR. While older technology, they remain viable for certain applications.
Advantages
- + Lower upfront cost
- + Simpler technology
- + Uses existing coax infrastructure
- + No network required
- + Less cybersecurity risk
Considerations
- - Limited resolution (max 1080p)
- - No AI or analytics
- - Separate power cables required
- - Limited remote capabilities
- - Harder to expand
Best for: Budget-conscious projects, existing coax infrastructure upgrades, simple monitoring needs
Wireless Video Surveillance Security Systems
Wireless systems use WiFi to transmit video, eliminating the need for data cables to each camera. They still require power (wired or battery).
Advantages
- + Easy installation
- + Flexible camera placement
- + No drilling for data cables
- + Good for renters
- + Battery options available
Considerations
- - WiFi interference issues
- - Signal range limitations
- - Less reliable than wired
- - Battery maintenance
- - More vulnerable to jamming
Best for: Small residential, temporary installations, areas difficult to wire, renters
Hybrid Systems
Hybrid video surveillance security systems combine multiple technologies—for example, wired IP cameras in critical areas with wireless cameras in hard-to-reach locations.
Best for: Properties with mixed requirements, phased upgrades, complex layouts

DIY vs Professional Video Surveillance Security System Installation
What 40 Years of Experience Taught Us
The biggest mistake we see is homeowners and business owners underestimating the complexity of video surveillance security system installation. Camera placement, cable routing, network configuration, and system integration require expertise that DIY guides simply can't provide. The "savings" from DIY often result in blind spots, unreliable recording, and systems that fail when you need them most.
DIY Installation
DIY may be appropriate for simple residential systems with 2-4 wireless cameras and basic monitoring needs.
When DIY Works:
- + Small home with 2-4 cameras
- + Wireless/battery-powered cameras
- + No integration requirements
- + Cloud storage acceptable
- + Basic monitoring needs
DIY Risks:
- - Poor camera placement/blind spots
- - WiFi reliability issues
- - No professional support
- - Security vulnerabilities
- - Void equipment warranties
Professional Installation
Professional video surveillance security system installation is recommended for businesses and any system requiring reliability.
Professional Benefits:
- + Optimal camera placement design
- + Proper wiring and infrastructure
- + Network security configuration
- + System integration (alarms, access)
- + Code compliance (NJ license required)
- + Warranty protection
- + Ongoing support and maintenance
- + Training and documentation

Video Surveillance Security System for NJ & PA Properties
Installing a video surveillance security system in New Jersey or Pennsylvania comes with specific considerations our team has navigated for 40 years:
New Jersey Requirements
- Licensing: Low-voltage installers need NJ license
- Audio recording: One-party consent state
- Permits: May be required for commercial installations
- Privacy laws: Cannot record in private areas
- Data retention: Industry-specific requirements
Pennsylvania Requirements
- Audio recording: Two-party consent state (stricter)
- Licensing: Varies by municipality
- Employee notification: Required for workplace cameras
- Privacy laws: Cannot record in private areas
- Signage: Recommended for public-facing cameras
Local Climate Considerations
Northeast winters require cameras rated for -20°F to 120°F operation. Our installations use weatherproof housings (IP66/IP67 rated) and heated enclosures for critical cameras. We also consider direct sunlight exposure, humidity levels, and salt air exposure for coastal areas like the Jersey Shore.
How to Choose the Right Video Surveillance Security System
Assess Your Security Needs
Identify areas needing coverage, specific threats, compliance requirements, and budget constraints.
Determine System Type
Choose IP for new installations with advanced needs, analog for budget or existing coax, wireless for flexibility.
Calculate Camera Requirements
Map coverage areas: entrances, parking, high-value zones, perimeters. Typically 1 camera per 200-500 sq ft for indoor, 1 per 1,000-2,000 sq ft outdoor.
Plan Storage Needs
Calculate based on camera count, resolution, and retention period. Consider local + cloud hybrid for redundancy.
Choose Installation Method
Professional installation recommended for 8+ cameras, businesses, and any system requiring integration or reliability.

?Frequently Asked Questions
What is a video surveillance security system?
A video surveillance security system is an integrated solution combining security cameras, recording devices (NVR/DVR), storage, monitoring software, and often remote access capabilities. Unlike standalone cameras, a complete system provides centralized management, remote viewing, and can integrate with access control and alarm systems for comprehensive property protection.
How much does a video surveillance security system cost?
Costs vary widely: Residential systems range $500-$4,000, small business systems $4,000-$10,000, and commercial systems $10,000-$100,000+. Factors include camera count, resolution, storage needs, and installation complexity. Professional installation typically adds 30-50% to equipment costs.
Should I choose professional or DIY installation?
Professional installation is recommended for businesses and systems with 8+ cameras. DIY may work for simple home setups with 2-4 wireless cameras. Professional installation ensures optimal placement, proper wiring, network security, and warranty protection.
Can I view my cameras remotely?
Yes, all modern video surveillance security systems support remote viewing via smartphone apps, web browsers, and desktop software. You can view live feeds, playback recordings, and receive alerts from anywhere with internet access.
How long does installation take?
Professional installation typically takes 1-2 days for residential (4-8 cameras), 2-3 days for small business (8-16 cameras), and 3-5+ days for larger commercial systems. Complex installations with extensive infrastructure may take longer.
Do video surveillance security systems work at night?
Yes, modern cameras include infrared (IR) night vision that can see 50-150+ feet in complete darkness. Color night vision cameras use supplemental lighting or starlight sensors for color imaging in low light conditions.
What camera resolution do I need?
1080p (2MP) is minimum for identification. 2K/4MP provides good detail for most applications. 4K/8MP is recommended for critical areas requiring forensic detail like entrances, cash registers, and vehicle identification.
How long can footage be stored?
Storage duration depends on camera count, resolution, and recording mode. Typical retention: 7-14 days residential, 30-60 days commercial. A 4-camera 1080p system needs about 2TB for 30 days of continuous recording. Cloud storage offers flexible retention options.
