IR bullet cameras with 5MP/4MP HD-TVI resolution provide high-definition surveillance for indoor and outdoor use. Their infrared capabilities enable night vision up to 30 meters, while weatherproof housing (IP66+) ensures durability. HD-TVI technology supports long-distance video transmission without latency, making them ideal for homes, businesses, and high-traffic areas requiring 24/7 security.
Why Is the Infrared Not Working on Security Cameras?
How Does HD-TVI Technology Enhance Security Camera Performance?
HD-TVI (High Definition Transport Video Interface) transmits uncompressed video over coaxial cables, maintaining 5MP/4MP resolution up to 500 meters. Unlike IP cameras, it avoids bandwidth issues, ensuring zero latency—critical for real-time monitoring. HD-TVI also supports analog systems, allowing seamless upgrades without replacing existing infrastructure.
One key advantage of HD-TVI is its backward compatibility with legacy coaxial wiring. This eliminates the need for costly rewiring when upgrading from analog to high-resolution systems. The technology also maintains consistent video quality over extended distances, whereas IP cameras often suffer from packet loss beyond 100 meters. For large properties or industrial sites, HD-TVI provides stable 25fps video feeds even in electromagnetic interference-prone areas like factories or parking garages.
| Feature | HD-TVI | IP Cameras |
|---|---|---|
| Max Distance | 500m | 100m |
| Latency | 0ms | 200-500ms |
| Installation Cost | $200-$500 | $800-$1,500+ |
Which Storage Solutions Work Best with HD-TVI Security Systems?
HD-TVI works with DVRs supporting H.265+ compression, reducing storage needs by 80%. For 24/7 5MP recording, use 4TB+ HDDs with RAID configurations. Cloud integration via hybrid DVRs allows remote backup. PoC (Power over Coaxial) systems simplify wiring by merging power and video signals into one cable.
When designing storage systems, consider the camera resolution and retention period. A 5MP camera recording at 15fps consumes approximately 1.2TB monthly with H.264 encoding. Upgrading to H.265+ cuts this to 250GB. For a 16-camera system, a 16TB NAS with RAID 5 provides 14 days of continuous recording with redundancy. Hybrid DVRs with dual-stream capabilities allow lower-resolution backups to the cloud while maintaining full-resolution local storage.
| Resolution | Daily Storage (H.264) | Daily Storage (H.265+) |
|---|---|---|
| 4MP | 32GB | 8GB |
| 5MP | 40GB | 10GB |
Why Is Weatherproof Design Critical for Outdoor IR Bullet Cameras?
Outdoor cameras face rain, dust, and temperature extremes. IP66+ rated housings prevent water ingress (-30°C to 60°C operational range). Reinforced metal casings resist vandalism, while built-in heaters/ventilators in premium models prevent fogging. Always verify Ingress Protection (IP) ratings and operational temperature ranges for your climate.
How Far Can IR Night Vision Cover in Low-Light Conditions?
Standard IR bullet cameras illuminate 20-30 meters using 850nm LEDs. Advanced models with EXIR 2.0 technology extend to 50 meters with even light distribution. For pitch-black environments, select cameras with Smart IR to avoid overexposure and 3D-DNR (Digital Noise Reduction) for clearer images.
“The shift to 5MP HD-TVI reflects demand for forensic-level detail in commercial security. We’re now combining IR bullet cameras with AI analytics—license plate recognition, crowd detection—all transmitted over existing coaxial lines. For homeowners, models with built-in spotlights and sirens are trending, deterring intruders before breaches occur.”
