1. Guardian Integrated Security
PPO License: 121089 | Google Reviews: 4.6 stars (50+ reviews) | BBB Rating: A+
Service Area: Los Angeles, Orange County, San Bernardino, Riverside, Ventura, San Diego
Guardian Integrated Security is the top-ranked security company in Los Angeles for commercial clients who need more than a guard at a gate.

Guardian protects over 2,700 businesses across California.
What Sets Guardian Apart
Live Video Monitoring (LVM): Guardian agents monitor feeds in real time, 24/7, from an LA-based operations center. When an intrusion is detected, agents issue live audio warnings through on-site speakers to prevent incidents from escalating. A human reviews every alert – not AI-only.
AI Camera Infrastructure: Guardian deploys AI-powered cameras that detect people, vehicles, and objects while filtering out false positives. All cameras are NDAA-compliant for government contractors and regulated industries.
Hybrid Security Model: Combining guards with live video monitoring cuts costs by up to 70% compared to running a full guard crew around the clock.
Pricing Transparency: Security guards start at $25-$30 per hour. Live video monitoring runs under $3 per hour.
Ideal For
- Commercial real estate, retail, and construction sites
- Properties needing physical presence and remote monitoring together
- Clients wanting one vendor for guards, cameras, and monitoring

What to Look for When Hiring a Security Company in Los Angeles
1. Verify the California PPO License
Any company that employs or contracts security guards in California must hold a Private Patrol Operator (PPO) license issued by BSIS. Operating without one is illegal. Verify any PPO number at the BSIS website before signing any contract.
2. Match the Service Model to Your Risk Profile
Guards provide a visible deterrent, handle access control, and can respond physically. Live video monitoring covers large perimeters 24/7 at a fraction of overnight guard staffing costs. Vehicle patrol provides mobile check-ins without a full-time guard. Most commercial properties benefit from combining two or more of these approaches.
As Jacob Ross, Security Specialist at Guardian Integrated Security, explains: “The biggest mistake Los Angeles businesses make is defaulting to guards for everything. Live video monitoring handles 80% of what a perimeter guard does, at under $3 an hour. The savings fund better guards where you actually need a physical presence.”
3. Ask About Technology Compliance
If your business works with government agencies or federal contractors, ask any vendor directly: “Are your cameras NDAA Section 889 compliant?” Cheaper CCTV vendors often deploy hardware without disclosing compliance implications.
4. Understand Contract Terms Before You Sign
Security contracts typically run 12-36 months. Confirm minimum guard hours, cancellation notice period (30-90 days is standard), who owns camera hardware if you end the relationship, and insurance coverage, at a minimum of $1M in general liability.
5. Ask About Response Time Guarantees
For live video monitoring, the industry standard is an alert-to-operator response time of under 30 seconds. Some budget providers use AI-only systems with no human review – alerts can go unactioned for minutes.
The Bottom Line
- Guards + cameras + patrol under one contract: Guardian Integrated Security is the only company on this list delivering all three.
- Established guard firm for large corporate or enterprise accounts: Guardian National Security or Security Guard Pros.
- Professional CCTV installation with strong reviews: San Diego CCTV Pros.
- Camera-first virtual guard solution: Virtual Guard CCTV.
For most Los Angeles commercial properties – especially those with after-hours risk, large perimeters, or multi-site portfolios – an integrated provider outperforms managing separate guard and camera vendors. Guardian Integrated Security’s hybrid model was built specifically for this scenario.
