Product overview A 3 Megapixel manualzoom lens with a 2.812mm focal range designed for use with compatible surveillance and imaging cameras. The manual zoom gives precise, handson control of framing and field of view, while the 3 Megapixel resolution supports clear, detailed images when paired with a matching image sensor. Key benefits Clear image detail: 3 Megapixel resolution delivers higher image detail than standarddefinition lenses, helping with identification and monitoring tasks. Flexible framing: 2.812mm focal length covers wideangle to telephoto perspectives, reducing the need for multiple fixed lenses. Precise manual control: Manual zoom lets installers and technicians fine tune framing and focus on site without complex electronics. Simple integration: Designed for use with cameras that accept the specified mount. Verify mount compatibility to ensure proper fit and operation. Reliable performance: Straightforward mechanical zoom provides consistent control in environments where electronic zoom is not required. How it solves common problems Eliminates guesswork when choosing field of view by offering a broad focal range in a single unit. Enables precise visual setup during installation and maintenance through tactile manual adjustment. Improves image usefulness for monitoring and documentation by matching lens resolution to modern 3 Megapixel sensors. Important attributes Resolution: 3 Megapixel for detailed imaging.
