The surveillance industry has undergone a massive shift toward cloud based solutions. Vendors like Verkada have disrupted the traditional NVR/DVR model by offering cameras that stream directly to the cloud. But is cloud based surveillance always the right choice?
Cloud Based Surveillance: The Advantages
Cloud based systems like Verkada offer compelling benefits:
- Zero on-site infrastructure: No NVR, no dedicated server room space, no UPS sizing for recording equipment
- Automatic updates: Firmware and software updates happen automatically
- Remote access: View any camera from anywhere with an internet connection
- AI analytics: Cloud platforms can leverage powerful AI for people counting, license plate recognition, and anomaly detection
- Scalability: Adding cameras is as simple as plugging them in
On Premise Surveillance: When It Still Makes Sense
On premise systems using Axis cameras or Ubiquiti UniFi Protect have their place:
- Bandwidth constraints: If your site has limited internet bandwidth, sending dozens of HD streams to the cloud may not be feasible
- Regulatory requirements: Some industries require video data to remain on-site
- Total cost of ownership: For very large deployments, on-premise can be more cost-effective over time
- Network independence: On-premise systems continue recording even if your internet goes down
The Hybrid Approach
For many organizations, the answer is a hybrid model: cloud management with on-site recording, or a mix of cloud cameras for critical areas and on premise cameras for the rest. This approach allows you to leverage the benefits of both architectures while mitigating their respective limitations.
Making the Decision
We evaluate several factors when advising clients on surveillance architecture:
1. Scale and Growth: Number of cameras and expected growth over the next 3-5 years. Cloud solutions scale more easily, but on premise can be more cost effective at very large scales.
2. Network Infrastructure: Available internet bandwidth and redundancy. Cloud systems require reliable, high-bandwidth connections. On premise systems can operate independently of internet connectivity.
3. Regulatory and Compliance Requirements: Some industries require video data to remain on-site. Healthcare, financial services, and government contracts often have specific data residency requirements.
4. Budget Model: Capital expenditure (CapEx) versus operational expenditure (OpEx) preference. Cloud solutions shift costs to OpEx, while on premise requires larger upfront investment.
5. Integration Requirements: Needs with access control systems, alarm systems, and other security infrastructure. Some platforms offer deeper integration than others.
The surveillance landscape is evolving rapidly. Whatever direction you choose, the most important thing is selecting a platform that integrates well with your broader security ecosystem and aligns with your organization's long-term technology strategy.
