Define Your Needs

Before buying, ask yourself:

Which areas need coverage?
Do you require indoor, outdoor, or both?
How many entry points, aisles, or zones will you monitor?

Answering these questions makes it easier to select CCTV cameras that match your layout and security goals.

Key Features to Consider

When you compare options in this CCTV camera buying guide, focus on these security camera features:

Resolution: Aim for at least 1080p HD. Higher resolutions (2K, 4K) capture more detail for face and license-plate recognition.
Night Vision: Infrared or low-light sensors let you see clearly in the dark.
Field of View: Wide-angle lenses cover more area with fewer cameras.
Motion Detection: Smart alerts notify you immediately when movement is detected.
Remote Access: Look for mobile app support and cloud or local DVR/NVR storage.
Durability: For outdoor cameras, pick IP66 or IP67 ratings to resist dust and rain.
Expandability: Ensure you can add cameras or features as your needs grow.

How to Select CCTV Cameras for Different Properties

Homes: Simple, wireless plug-and-play cameras work well. Choose user-friendly setups for easy DIY installation.
Small Businesses: A mix of indoor and outdoor cameras with DVR solutions gives centralised recording and motion alerts.
Large Sites: Enterprise-grade IP cameras, server-based storage, and advanced analytics (such as line crossing or facial recognition) offer robust coverage.

CCTV Installation Tips

Proper installation is as crucial as choosing the right system. Follow these tips:

Plan camera locations to avoid blind spots and cover all key areas.
Mount cameras 8–10 feet high for tamper resistance and clear identification.
Conceal cables and use cable conduits to prevent damage.
Test each camera’s view in different lighting before final mounting.
Secure network settings with strong passwords and firmware updates.

Long-Term Considerations

A CCTV system is an investment, so plan carefully:

Storage Capacity: More cameras and higher resolution mean more disk space.
Maintenance Plans: Opt for annual maintenance contracts (AMC) for regular checks and updates.
Scalability: Choose DVR/NVR or network setups that can handle extra cameras and new features.
