The PTZ HD TVI 1080p Coax CCTV Camera combines pan-tilt-zoom flexibility, high-definition 1080p resolution, and coaxial cable reliability for robust surveillance. It supports real-time remote control, seamless upgrades from analog systems, and crisp imaging in low-light conditions. Ideal for large-scale monitoring, this camera integrates advanced TVI technology to deliver cost-effective, high-performance security solutions.
How Does 1080p Resolution Enhance Surveillance Clarity?
1080p resolution provides 1920×1080 pixels, capturing fine details like facial features or license plates. This clarity is critical for forensic analysis and real-time monitoring. Unlike lower resolutions, 1080p reduces pixelation during zooming, ensuring usable footage even when magnifying distant objects by 300%.
Modern 1080p TVI cameras utilize progressive scanning rather than interlaced formats, eliminating motion blur for moving targets. The 2.1-megapixel sensor outperforms 720p by 125% in pixel density, enabling identification of objects as small as 2.5cm at 15 meters. Advanced compression like H.265 reduces storage needs by 50% compared to H.264 while maintaining detail integrity. For optimal results, pair with a DVR supporting 2560×1440 resolution to future-proof for higher-resolution cameras in mixed systems.
| Resolution | Pixel Count | Storage/Day (H.265) |
|---|---|---|
| 720p | 1.0MP | 32GB |
| 1080p | 2.1MP | 48GB |
What Are the Advantages of Coaxial Cable in CCTV Setups?
Coaxial cables provide interference-resistant transmission, critical in environments with high electromagnetic noise (e.g., factories). They support Power over Coax (PoC), eliminating separate power lines. Existing coaxial infrastructure can be reused during upgrades, reducing installation costs by up to 60% compared to rewiring for IP cameras.
RG59 coax maintains 1080p signal integrity for 300 meters versus Cat6 Ethernet’s 100-meter limit for IP cameras. Quad-shielded coaxial cables reduce signal attenuation to 6dB per 100m at 50MHz, compared to 20dB loss in UTP cables. For PTZ models, coaxial control signals (RS-485) can daisy-chain up to 4 cameras on one cable run. Modern Siamese cables integrate 18/2 power conductors alongside coax, simplifying installations where separate power isn’t available.
| Cable Type | Max 1080p Distance | Cost per 100m |
|---|---|---|
| RG59 | 500m | $35 |
| Cat6 | 100m | $85 |
“While IP dominates new installations, coax-based TVI remains vital for retrofits and harsh environments. The emergence of 4K TVI over coax (Ultra 845) shows the technology’s scalability. Expect AI-enhanced TVI cameras by 2025, enabling edge-based analytics like license plate recognition without full IP migration.” — John Carter, Security Systems Integrator
FAQ
- Does PTZ HD TVI Work with PoE?
- No. TVI uses coaxial cables, not Ethernet. However, Power over Coax (PoC) variants allow single-cable power and video transmission up to 500m.
- How Many PTZ Cameras Can a DVR Support?
- Most 16-channel TVI DVRs support 4 PTZ cameras due to high bandwidth needs. Ensure the DVR has RS-485 ports for PTZ control protocols like Pelco-D.
- Can TVI Cameras Integrate with Smart Home Systems?
- Yes. Through ONVIF compatibility, TVI feeds can stream to platforms like Alexa or Google Home via middleware encoders, though with limited PTZ control.
