Introduction

Modern body-worn cameras (BWCs) and body-worn video (BWV) systems are no longer just recording devices—they are connected tools capable of real-time video streaming. Law enforcement agencies now rely on live streaming to improve situational awareness, officer safety, and incident response.

But streaming technology varies. Many agencies ask: Should my body cameras use 4G, LTE, or Wi-Fi for live streaming? Understanding the differences helps departments select the right police technology solution for their operations.

What Is 4G, LTE, and Wi-Fi in Body Cameras?

4G and LTE are cellular technologies that transmit data over wide-area networks, allowing body cameras to stream footage live from virtually anywhere with a signal.

Wi-Fi streaming, on the other hand, relies on local wireless networks to transmit video, often within a police station, campus, or city network infrastructure.

Each streaming method has unique benefits and limitations for law enforcement applications.

4G Streaming: Pros and Cons

4G streaming offers reliable connectivity for real-time video transmission over broad geographic areas.

Advantages:

• Wide coverage: Officers can stream live video from almost anywhere in the city or county.

• Integration with DEMS: Footage can upload directly to Digital Evidence Management Systems in real time.

• Improved situational awareness: Command centers can monitor incidents as they happen, supporting rapid decision-making.

Disadvantages:

• Network variability: Signal strength can fluctuate, causing buffering or dropped frames.

• Data costs: Cellular data plans can be expensive, particularly for continuous live streaming.

LTE Streaming: Pros and Cons

LTE (Long-Term Evolution) is a faster, more efficient cellular standard than standard 4G. It offers:

Advantages:

• High-speed data transfer: Supports HD video streaming with fewer interruptions.

• Low latency: Real-time communication with command centers is faster, critical during high-risk incidents.

• Nationwide coverage: LTE networks are widely available, making it suitable for mobile officers.

Disadvantages:

• Signal dependency: Remote or underground areas may still experience connectivity issues.

• Ongoing data fees: High-quality HD streaming consumes significant data.

Wi-Fi Streaming: Pros and Cons

Wi-Fi streaming relies on local networks, providing an alternative to cellular options.

Advantages:

• Cost-effective: Eliminates ongoing cellular data fees.

• High-quality video: Wi-Fi networks often support higher bandwidth, allowing for HD or even 4K streaming.

• Secure network: Internal Wi-Fi networks reduce exposure to public network vulnerabilities.

Disadvantages:

• Limited range: Officers must be within Wi-Fi coverage to stream live.

• Network congestion: Multiple devices on the same network can affect streaming quality.

Choosing the Right Streaming Technology

When deciding between 4G, LTE, and Wi-Fi streaming, agencies should consider:

1. Operational environment: Urban vs. rural deployment affects coverage needs.

2. Incident type: High-risk operations may benefit from LTE’s low latency for instant oversight.

3. Budget: Wi-Fi streaming reduces data plan costs but limits mobility.

4. Integration needs: Ensure compatibility with Digital Evidence Management Systems (DEMS) for secure storage and retrieval.

5. Officer safety: Reliable streaming supports rapid decision-making and coordination during critical incidents.

Conclusion

Understanding the differences between 4G, LTE, and Wi-Fi streaming helps law enforcement agencies choose the best body-worn camera solution for their operations.

• 4G offers broad coverage with moderate speed.

• LTE provides faster, low-latency streaming ideal for critical incidents.

• Wi-Fi delivers high-quality, cost-effective video for localized environments.

The right streaming method, combined with high-definition video, audio capture, and secure DEMS integration, ensures reliable, actionable, and court-ready evidence, improving officer safety, operational efficiency, and public trust.
