• Requires significant storage infrastructure
• Overkill for many applications

The Resolution-Distance Relationship

Camera resolution must match viewing distance and identification requirements. A 4K camera becomes meaningless if subjects appear too small in the frame.

Facial Identification Requirements:

• Close range (0-10 feet): 1080p adequate
• Medium range (10-25 feet): 4MP recommended
• Long range (25+ feet): 4K may be necessary

General Monitoring:

• Parking lots: 4MP provides good overview
• Retail interiors: 1080p often sufficient
• Perimeter security: Resolution less important than coverage

Storage Impact of Resolution

Higher resolution creates exponentially larger file sizes, affecting both storage costs and network bandwidth.

Daily Storage Requirements (24-hour recording):

• 1080p: 20-40 GB per camera
• 4MP: 40-80 GB per camera
• 4K: 80-160 GB per camera

Network Bandwidth Consumption:

• 4K: 15-25 Mbps per camera

Compression Technology Impact

Modern cameras use advanced compression algorithms that significantly affect file sizes regardless of resolution.

H.264 vs H.265: H.265 (HEVC) compression can reduce file sizes by 30-50% compared to H.264 while maintaining image quality. Many of these higher resolution cameras also have advanced video codecs, which offer dynamic frame rate or bit rate adjustments, or other features to help reduce total bandwidth.

Smart Compression:

• Region of Interest (ROI): Higher quality for important areas
• Dynamic bitrate: Adjusts quality based on motion and content
• Event-based recording: Only records when motion detected

When 4K Actually Matters

Despite marketing hype, 4K provides genuine benefits only in specific scenarios:

Justified 4K Applications:

• Large area coverage where digital zoom is necessary
• Critical identification needs (banks, jewelry stores)
• Evidence gathering requiring forensic detail
• Future-proofing long-term installations

4K Probably Unnecessary:

• Basic home security with adequate camera placement
• Budget-conscious installations where more cameras matter more
• Bandwidth-limited environments
• Legacy storage systems unable to handle large files

Optimization Recommendations

For Most Home Users: Choose 4MP cameras positioned correctly rather than fewer 4K cameras. Better coverage beats higher resolution.

For Business Applications: Mix resolutions based on specific needs – 4K for cash registers and entrances, 1080p for general area monitoring.

For Large Deployments: Consider storage and bandwidth infrastructure carefully. Sometimes 1080p cameras with better lenses outperform 4K cameras with cheap sensors.

Foire aux questions {#faq}

What’s the difference between CCTV and IP cameras?

CCTV (Closed-Circuit Television) cameras use analog signals transmitted through coaxial cables to a Digital Video Recorder, while IP cameras transmit digital video over network cables to a Network Video Recorder or cloud storage. IP cameras offer higher resolution, smart features, and remote access, while traditional CCTV provides simpler, more cost-effective surveillance for basic applications.

How many megapixels do I need for security cameras?

For most security applications, 4MP (2K) cameras provide the optimal balance of image quality and storage requirements. 1080p is adequate for general monitoring, while 4K cameras are beneficial for areas requiring detailed identification like cash registers or main entrances. Higher resolution isn’t always better if it compromises other factors like low-light performance or storage capacity.

Should I choose wired or wireless security cameras?

Wired cameras offer superior reliability, consistent power through PoE, and better security against interference. Wireless cameras provide installation flexibility and work well for temporary deployments or areas where cable running is difficult. Many professional installations use a hybrid approach, with wired cameras for critical areas and wireless for supplementary coverage.

How long should I store security footage?

Most residential applications benefit from 30-60 days of storage, while businesses typically require 90-180 days depending on industry requirements. Legal considerations, insurance requirements, and available storage capacity all influence retention periods. Cloud storage can extend retention for critical events while maintaining shorter periods for general footage.

Do security cameras work without internet?

Yes, most security cameras can record locally to NVR hard drives or SD cards without internet connectivity. However, internet access is required for remote viewing, cloud storage, mobile alerts, and software updates. Some cameras store footage locally during internet outages and upload when connectivity returns.

What resolution is best for identifying faces?

For reliable facial identification, subjects should occupy at least 80-100 pixels between the eyes. This typically requires 4MP cameras for identification at 25 feet, or 4K cameras for identification at 40+ feet. Proper camera positioning and lighting often matter more than raw resolution for identification purposes.

How much storage space do security cameras need?

Storage requirements depend on resolution, compression, frame rate, and retention period. Typical requirements are 20-40GB per day for 1080p cameras, 40-80GB for 4MP cameras, and 80-160GB for 4K cameras. A 4TB drive can store approximately 30 days of footage from 8 4MP cameras with modern compression.

Can neighbors complain about my security cameras?

Property owners can generally install cameras monitoring their own property, but cameras cannot deliberately observe neighbors’ private areas like backyards, windows, or private entrances. Check local ordinances for specific requirements about camera placement, signage, and neighbor notification. Good neighbor relations often prevent legal disputes.

How do I prevent security cameras from being hacked?

Protect cameras through strong unique passwords, regular firmware updates, network segmentation, encrypted connections, and disabling unnecessary features. Avoid default passwords, use VPNs for remote access, and choose cameras from reputable manufacturers with good security update records. Regular security audits help identify vulnerabilities.

What’s the best height for mounting security cameras?

8-10 feet provides optimal height for facial identification while remaining difficult to tamper with. Higher mounting (12-15 feet) works well for area overview but may compromise identification capability. Consider the camera’s field of view, lighting conditions, and specific monitoring objectives when determining mounting height.
