cameras surveillance Sourcing Overview

Avoiding Resolution Mismatches Overlooking the horizontal resolution can lead to inadequate image clarity; for example, choosing a camera with only 420 TVL might not meet your surveillance detail needs compared to options offering up to 650 TVL.

Specify Night Vision Capabilities Clearly Insist on cameras that support infrared night vision with a range suitable for your environment, such as the 400 m capability listed, to ensure reliable performance in low-light conditions.

Lens Type and Field of View Insights In practice, suppliers often provide fixed lenses like 3.6/4 mm or variable zoom lenses such as 2.8-12 mm; selecting between these affects your coverage area, with wide-angle or spherical lenses offering broader monitoring scopes.

Certification Impact on Compliance and Quality Certifications like CE, FCC, RoHS, and ISO 9001 can account for up to 20% of the total product cost but directly affect regulatory compliance and long-term reliability, making them essential for procurement decisions.
