The DT-N 91 CCTV tester is a handheld diagnostic tool designed for field technicians installing or maintaining analog and IP surveillance systems. It features a 3.5-inch LCD screen with a resolution of 480 x RGB x 32, enabling clear video preview and focus verification without requiring a monitor. The device supports digital zoom up to 4x, allowing precise evaluation of camera field of view and image sharpness during installation.
It operates on standard DC 12V input and accepts BNC and RCA video inputs, compatible with most analog CCTV cameras using CVBS signals. The unit is built with a compact aluminum alloy casing, weighing approximately 280 grams, making it suitable for extended on-site use. While the listing does not specify operating temperature range, typical industrial-grade testers in this class function reliably between -10°C and 50°C.
This tester is commonly used by security integrators, CCTV installers, and maintenance teams in commercial, retail, and residential applications. Buyers typically order in quantities of 5 to 50 units for deployment across multiple job sites. Trade terms are offered as FOB Guangzhou or CIF destination port, with packaging in individual foam-lined boxes. Lead time and minimum order quantity are not stated and must be confirmed directly with the supplier.

Before ordering, verify the exact model compatibility with your existing camera systems. Confirm whether the DT-N 91 supports your camera's output format, such as CVBS or any proprietary signal. Request a sample unit if possible, as visual performance on the 3.5-inch screen may vary under different lighting conditions. Do not assume compatibility with HD or IP cameras unless explicitly confirmed by the supplier.
Confirm the Incoterms offered - FOB Guangzhou is common, but CIF terms may affect total landed cost. Lead time is not stated; typical production cycles for such devices range from 7 to 21 days after order confirmation. Payment terms are likely T/T in advance or LC, but must be negotiated directly. Packaging should be inspected for shock absorption, as these units are sensitive to transport vibration.
For quality assurance, request a sample test report showing video output clarity and zoom functionality. Ask for photos of the unit under test conditions, including zoomed images at full resolution. Ensure that each unit is individually tested before shipment and that a serial number is marked on the device. Request a packing list and test certificate with each shipment to verify authenticity and functionality.
