Model and connections

Dahua B1A51P 5MP HDCVI Bullet Camera: Model: B1A51P. Resolution: 5 MP. Format: Bullet. Video system: HDCVI. Power: 12 V DC.

Check supported frame rate at the selected resolution before pairing the camera with an older DVR. Confirm the lens variant and night-view requirements. The price is for a camera, with cabling, power and recording equipment specified separately.

Building the installation

The supply price applies to the named equipment. Confirm the lens, hardware revision and included accessories where relevant. Cables, storage media, mounting boxes, subscriptions and labour should appear separately on the order unless expressly included. This keeps comparisons between equipment-only and installed-system quotations meaningful.

Compare compatible items in the CCTV camera and recording equipment range when preparing the system schedule. Plan any required monitoring notices alongside the site safety signs and labels, with placement agreed for the intended premises.

Setup and maintenance

Check a recorded sample from every channel after the camera is positioned. Inspect connectors, power joints and cable protection when image noise or intermittent loss appears. Keep the camera lens clean and adjust lighting or position if nearby surfaces reflect illumination back into the lens.

Consult the manufacturer product and support information for the exact delivered model. Keep commissioning details available for future changes and limit system access to authorised users. Browse the full safety equipment range when coordinating the remaining building and workplace equipment.
