Short Answer: 5MP CCTV cameras (2560×1920 pixels) provide 77% more pixels than 1080p (1920×1080), delivering sharper details for identifying license plates or facial features. However, 1080p systems use 30-50% less storage and bandwidth, making them cost-effective for general monitoring. Choose 5MP for high-detail areas like entrances, and 1080p for wide-coverage zones with budget constraints.
What Are the Main Types of CCTV Cameras?
What Are the Key Differences Between 1080p and 5MP Resolutions?
1080p (2MP) offers 1920×1080 pixels, while 5MP provides 2560×1920 pixels—a 77% increase in pixel density. This allows 5MP cameras to capture finer details like vehicle license plates or clothing patterns. However, higher resolution requires more advanced lenses: a 5MP camera needs at least a 3.6mm lens with f/1.6 aperture to outperform 1080p in clarity.
How Does Image Quality Compare in Real-World Scenarios?
In daylight, 5MP resolves objects up to 65 feet away clearly vs. 1080p’s 45-foot range. At night, 1080p often performs better with infrared (IR) cut filters due to larger individual pixels (2.8µm vs. 5MP’s 2.0µm) capturing more light. Tests show 1080p maintains 20% better low-light sensitivity at 0.05 lux compared to equivalent 5MP models.
What Storage and Bandwidth Requirements Exist for Each?
A 5MP camera recording at 30 FPS consumes ~3,500MB/hour with H.265 encoding versus 1080p’s 1,800MB/hour. For 24/7 operation, monthly storage needs are 2.5TB (5MP) vs. 1.3TB (1080p). Bandwidth demands also differ: 5MP requires 8-12Mbps per camera compared to 1080p’s 4-6Mbps, impacting network infrastructure costs by 35-60%.
| Resolution | Hourly Storage (H.265) | Monthly Storage | Bandwidth per Camera |
|---|---|---|---|
| 1080p | 1.8GB | 1.3TB | 4-6Mbps |
| 5MP | 3.5GB | 2.5TB | 8-12Mbps |
Advanced compression formats like H.265+ can reduce 5MP storage needs by 40%, but require processors supporting 80Mbps throughput. For multi-camera installations, 16-channel NVRs need 256TB raw capacity for 5MP systems versus 128TB for 1080p. Consider RAID configurations for redundancy in high-resolution setups.
When Does 5MP Outperform 1080p for Facial Recognition?
5MP cameras achieve 90% facial recognition accuracy at 25 feet versus 1080p’s 15-foot limit, per NIST benchmarks. This makes 5MP ideal for access control points. However, this requires 120dB WDR to handle backlighting and 30 FPS recording to capture facial movements—features often adding 40-70% to camera costs compared to basic 1080p models.
Can Existing Systems Support 5MP Cameras?
Most modern DVRs support 5MP via coaxial cables up to 300 feet, but older BNC systems may need HDMI converters. For IP systems, CAT6 cables and PoE++ switches (802.3bt) are recommended to handle 5MP’s 12W power draw vs. 1080p’s 7W. Network upgrades cost $120-$250 per camera for full 5MP compatibility.
| Component | 1080p Requirement | 5MP Requirement |
|---|---|---|
| Cabling | CAT5e | CAT6 |
| Switch Port | PoE (15W) | PoE++ (30W) |
| Backup Power | 500VA UPS | 1000VA UPS |
Legacy analog systems using TVI 3.0 can support 5MP at reduced frame rates (15 FPS max). For hybrid installations, ensure your video management software (VMS) supports mixed resolutions without downscaling. Test network latency with 5MP test streams before full deployment.
“While 5MP provides superior pixel density, pairing it with inferior lenses negates the advantage. We recommend 5MP sensors only with 6-element glass lenses and 1/1.8″ optical formats. For 80% of retail environments, 1080p with AI analytics delivers better ROI than raw 5MP resolution.”

FAQs
- Does 5MP CCTV Require Special Monitors?
- Yes. To fully utilize 5MP, use 4K (3840×2160) monitors. Standard 1080p displays downsample 5MP footage, losing 41% of captured detail.
- Are 1080p Cameras Becoming Obsolete?
- No. 1080p still dominates 68% of the market (IMS 2023) due to balanced performance. Industry experts project 1080p as mainstream through 2028, particularly for IoT-enabled devices with edge analytics.
- How Does HDR Affect 1080p vs 5MP Comparisons?
- True WDR (140dB+) enables 5MP to outperform in high-contrast scenes. However, 1080p with 3D-DNR noise reduction often matches 5MP in dynamic range at 60% lower compute load.
