Professional vs DIY. Wired vs Wireless. Monitored vs Unmonitored. Make the right choice for your property with expert guidance from licensed security professionals.
Choosing the wrong security system type can cost you thousands in wasted investment, leave vulnerabilities in your protection, void insurance coverage, or create ongoing frustration with false alarms and technical issues. With hundreds of security system options available, the decision between professional vs DIY, wired vs wireless, and monitored vs unmonitored systems significantly impacts your security effectiveness, total cost of ownership, and peace of mind.
This comprehensive guide compares all major security system types to help you make an informed decision. We will examine installation methods, wiring technologies, monitoring options, and technology platforms with honest pros and cons for each. Whether you are securing a home, business, or commercial facility in New Jersey or Pennsylvania, you will learn which system type best fits your property, budget, and security requirements.
Licensed Expert Guidance: Security Dynamics Inc. is a New Jersey licensed security contractor (Fire NJ P00747, Burglar NJ 34BA00089500) with 15+ years installing all system types. This guide provides unbiased, expert advice based on real-world installations across 2,000+ properties in Mercer County NJ and Bucks County PA.
The installation method is your first major decision. Professional installation provides guaranteed performance and expertise but costs more upfront. DIY installation saves money initially but requires technical skills and time investment. Here is how they compare:
Licensed technicians design, install, and configure your system with guaranteed performance and code compliance.
Best For: Businesses, large homes (2,500+ sq ft), commercial properties, complex layouts, insurance compliance requirements, or anyone wanting guaranteed performance without DIY hassle.
Typical Cost: $800-$2,500 (homes), $2,000-$10,000+ (businesses) for installation. Monitoring: $30-$60/month.
You purchase equipment and install the system yourself using provided instructions and mobile app guidance.
Best For: Apartments, rentals, small homes (under 1,500 sq ft), tech-savvy users, tight budgets, temporary housing, or properties where running wires is impractical.
Typical Cost: $200-$800 for equipment. Monitoring: $0-$25/month (or self-monitor for free).
How your sensors communicate with the control panel affects reliability, installation cost, and long-term maintenance. Each wiring type has distinct advantages:
Sensors connect to the control panel via physical wires (usually 22-gauge 4-conductor). Most reliable option but requires running wires through walls.
Best For: New construction, commercial buildings, permanent installations, properties with unfinished basements/attics, metal buildings, or when maximum reliability is required.
Sensors communicate via radio frequency (usually 319.5 MHz or 900 MHz) to the control panel. Clean installation with no wires.
Best For: Existing homes, rental properties, finished buildings, properties where wire fishing is impractical, quick installations, or temporary housing.
Control panel is wired to power and phone/internet, but sensors are wireless. Combines the reliability of wired infrastructure with wireless sensor flexibility.
Security Dynamics Recommendation: We install hybrid systems for 85% of our customers. This approach provides the reliability of wired infrastructure with the flexibility and cost-effectiveness of wireless sensors. You get the best protection without the expense and disruption of running wires to every door and window.
How your alarms are monitored determines your emergency response time and insurance eligibility. This decision affects both your monthly costs and your protection level during actual emergencies.
UL-listed central station receives your alarms 24/7/365 and dispatches police/fire/medical within 30-90 seconds. Operators verify alarms before dispatch to reduce false alarm fees.
Best For: All businesses (liability protection), families with children, elderly occupants, anyone who travels frequently, properties with valuables, insurance discount seekers, or anyone wanting fastest emergency response.
Typical Cost: $30-$45/month (residential), $45-$60/month (commercial). Insurance savings often cover the entire monitoring cost.
Alerts come directly to your smartphone. You receive notifications and must call 911 yourself if there is an actual emergency.
Best For: Budget-conscious homeowners who are always available to respond, tech-savvy users comfortable with smartphone apps, rental properties, vacation homes you monitor remotely.
Risk Consideration: Response time is significantly slower (you receive alert → you verify → you call 911 → police dispatched). Professional monitoring dispatches within 90 seconds; self-monitoring can take 5-15 minutes.
Alarms sound locally at your property only. No alerts to you, no central station, no police dispatch. Relies entirely on sirens scaring intruders away or neighbors calling police.
Not Recommended: Unmonitored systems provide minimal protection. Professional burglars disable local sirens in seconds. Without dispatch, emergency response time can be 15-30+ minutes (if neighbors even call police). For the small cost of monitoring ($30-$60/month), verified professional dispatch is worth the investment.
Use this framework to select the right security system type for your specific situation:
Businesses/Commercial: Professional installation + Wired or Hybrid + 24/7 Professional Monitoring (required for insurance and liability protection)
Large Homes (2,500+ sq ft): Professional installation + Hybrid + 24/7 Professional Monitoring (insurance discounts pay for monitoring)
Medium Homes (1,500-2,500 sq ft):Professional installation + Wireless or Hybrid + Professional Monitoring (best value and protection)
Small Homes/Apartments: DIY + Wireless + Self-Monitoring or Professional Monitoring (depends on budget and tech comfort)
Rentals: DIY + Wireless + Self-Monitoring (portable when you move)
Under $500 total: DIY wireless + no monitoring or self-monitoring ($200-$400 equipment + $0-$15/mo)
$500-$1,500 budget: DIY wireless + professional monitoring ($300-$600 equipment + $30-$40/mo) OR professional wireless install with monitoring
$1,500-$3,000 budget: Professional wireless or hybrid install + professional monitoring (recommended for most homes)
$3,000+ budget: Professional wired or hybrid + professional monitoring + video surveillance + access control (comprehensive protection)
Remember: Insurance discounts (10-20%) with professional monitoring often cover the entire monitoring cost ($360-$720/year savings on a $3,000-$6,000 insurance premium).
High Technical Skills: DIY systems can save 40-60% on installation costs if you are comfortable with WiFi setup, smartphone apps, and troubleshooting.
Moderate Technical Skills: Consider professional installation to guarantee proper setup, but you can manage the system yourself afterward via mobile app.
Low Technical Skills: Professional installation + professional monitoring provides full-service support with no technical knowledge required.

For most homes, a professionally installed wireless system with 24/7 monitoring provides the best protection. This combination offers reliable performance, professional installation guarantees, fast emergency response (police/fire dispatch within 30-90 seconds), and no DIY installation hassles. Expect to invest $800-$2,500 for installation plus $30-$60/month for monitoring. The peace of mind and verified response make this the gold standard for residential security.
Professional installation is better for most properties because it guarantees optimal sensor placement, proper system configuration, code compliance, and warranty coverage. DIY systems cost 40-60% less upfront but you sacrifice installation expertise, warranty protection, and often monitoring quality. Choose DIY if you have strong technical skills, a simple property layout, and a tight budget. Choose professional installation for businesses, large homes, complex properties, insurance discounts (10-20% savings), or if you want guaranteed performance.
Choose wired systems for new construction, commercial properties, or permanent installations where maximum reliability matters. Wired systems never need battery replacements, cannot be jammed, and have zero latency. Choose wireless for existing buildings, rentals, or properties where running wires is impractical or expensive. Wireless systems install 60-70% faster and cost $500-$1,500 less for installation. Hybrid systems (wired control panel + wireless sensors) offer the best balance for most properties.
You need 24/7 professional monitoring if you want police/fire dispatch, insurance discounts (10-20%), or cannot respond to alerts yourself (travel frequently, work nights, elderly occupants). Professional monitoring costs $30-$60/month but emergency services are dispatched within 30-90 seconds even if you cannot respond. Self-monitoring costs $0-$15/month and works if you are always available to receive alerts and can call 911 yourself. Businesses should always use professional monitoring for liability protection and insurance compliance.
The most affordable option is a DIY wireless system with self-monitoring: $200-$500 for equipment, $0-$15/month monitoring. Example: Ring Alarm ($200) or SimpliSafe ($250). However, this sacrifices professional installation, warranty coverage, insurance discounts, and verified police dispatch. For better value, consider professionally installed wireless with monitoring: $800-$1,500 installation + $30-$45/month. The insurance discount (10-20%) often pays for monitoring, and you get guaranteed performance, warranty coverage, and proper permitting.
Yes, but it depends on your starting system. Professional systems (Security Dynamics, ADT, Honeywell) can usually add cameras, sensors, access control, or upgrade to cellular monitoring without replacing the control panel. DIY systems (Ring, SimpliSafe) have limited expansion because they use proprietary ecosystems - you cannot mix brands. Wired systems can add wireless sensors using hybrid panels. Wireless systems can add wired components but require power/wiring installation. Plan for future expansion by choosing a professional system with modular architecture and industry-standard protocols.
