I. Planning and Site Survey: The Foundation of a Successful Installation

Before even thinking about drilling holes or running cables, a thorough site survey is crucial. This involves carefully assessing your property in Dongguan, considering several key factors:

A. Defining Security Needs: What areas need monitoring? Are you focusing on perimeter security, interior surveillance, or both? Identifying specific vulnerabilities will dictate camera placement and the type of cameras required (e.g., bullet cameras for exterior use, dome cameras for discreet indoor monitoring).

B. Network Infrastructure: Do you have existing network infrastructure (e.g., Ethernet cables, Wi-Fi network) that can support the CCTV system? If not, you'll need to plan for cable routing and potential network upgrades. Dongguan's building structures may present unique challenges, so careful consideration of wall types and potential obstructions is vital.

C. Power Supply: Ensure adequate power outlets are available near each proposed camera location. You might need to install additional power outlets or consider using Power over Ethernet (PoE) to simplify wiring.

D. Local Regulations: Always comply with local regulations in Dongguan regarding CCTV installation. This may include obtaining necessary permits and adhering to specific guidelines on camera placement, particularly in public areas.

II. Equipment Selection: Choosing the Right Components

The success of your CCTV installation hinges on selecting the right components. This includes:

A. Cameras: Consider the resolution (higher resolution offers better image quality), type (bullet, dome, PTZ – Pan-Tilt-Zoom), and features (night vision, weatherproofing). The choice depends on your specific needs and budget.
