AHD/HD‑CVI/HD‑TVI Security Camera APTI H51V21-28W 2–5 MP, 2.8 mm Lens

The AHD/HD‑CVI/HD‑TVI Security Camera APTI H51V21-28W is an analog/HD multi-format surveillance camera that supports AHD, HD‑CVI and HD‑TVI signal standards and provides imaging at either 2 MP or 5 MP depending on the selected mode. Fitted with a fixed 2.8 mm wide-angle lens, the unit is designed for general indoor and outdoor monitoring when installed in a suitable housing. The camera is suitable for perimeter monitoring, retail and office security, and building entry coverage where a broad field of view is required.

Advantages

The camera’s multi-format compatibility simplifies integration with different DVR systems and existing cabling infrastructure. A choice of 2 MP or 5 MP imaging modes allows balancing image detail and storage or transmission requirements. The fixed 2.8 mm lens delivers a wide field of view for covering larger areas from a single mounting point. The device is intended for versatile deployment in standard surveillance scenarios and is compatible with typical analog HD recorders and monitors.

Suitable for

• Perimeter and outdoor area surveillance (when installed in appropriate weatherproof housing)
• Retail floor and point-of-sale monitoring
• Office interior security and common areas
• Building entrances, corridors and stairwells requiring wide-angle coverage

Key specifications

• Signal standards: AHD, HD‑CVI, HD‑TVI multi-format compatibility
• Image resolution modes: 2 MP and 5 MP (mode dependent)
• Lens: fixed 2.8 mm wide-angle lens
• Mounting type: fixed camera body for wall or ceiling mounting (housing dependent for outdoor use)
• Video output: analog/HD output compatible with corresponding DVR inputs

How to use

Install the camera on a stable surface or mount using a compatible bracket; for outdoor use place the camera inside an appropriate weatherproof housing rated for the environment. Connect the video and power cabling to a compatible HD DVR or monitor supporting AHD, HD‑CVI or HD‑TVI inputs. Select the desired resolution mode (2 MP or 5 MP) and configure recorder settings for encoding and frame rate to match storage and bandwidth needs. Position the camera so the fixed 2.8 mm lens covers the target area with the required field of view, and adjust mounting angle to minimize glare and obstructions.

Usage recommendations

For reliable outdoor operation, use a weatherproof housing and corrosion-resistant mounting hardware. Match the camera’s signal format with the recorder during installation to ensure proper video display. When requiring greater identification detail at longer distances, consider mounting the camera closer to the scene or using a model with a narrower field lens. Regularly inspect connections and clean the lens surface to maintain image quality.
