Import 5.7 Inch Underwater Fishing Video Camera — Buy in wholesale FOB from Supplier in China

The 5.7 inch underwater fishing video camera from Shenzhena Goodwilla Electricala Co., Ltd. combines a surface-mounted CRT monitor with a submersible camera head for real-time visual observation beneath the waterline. The monitor employs a 5.7 inch cathode-ray tube rather than a modern flat-panel display, a design choice that trades depth and weight for the high contrast and rapid response suited to monochrome video signals. Video system compatibility covers both PAL and NTSC formats, allowing use across European, Asian, and North American territories without transcoding hardware. Resolution is specified at 380 TV lines for the monitor, with the camera head delivering 300,000 effective picture pixels through a 1/3 inch PAL or 1/4 inch NTSC black-and-white CCD image sensor.

The camera module integrates 21 infrared LEDs to provide active illumination in turbid or deep water where ambient light does not penetrate. Minimum illumination is rated at 0.2 lux, indicating operation in near-darkness when the IR array is active. The lens carries a 6 mm focal length in PAL configuration or 4.5 mm in NTSC, yielding moderately wide angles suitable for monitoring nets, traps, or reef structure at short to medium range. Automatic compensation circuitry adjusts video levels as lighting conditions shift. The ABS plastic housing encases the camera electronics, and the complete system draws 250 mA at 12 V DC for the camera and 9.6 W total for the monitor, permitting extended operation from a 12 V marine battery without excessive drain.

Intended users include commercial fishers, aquaculture operators monitoring pond or cage conditions, and recreational anglers seeking to identify species or assess bottom structure. The system is packaged in a carrying case with a charger box to prevent battery overcharge, and a cigarette-lighter adapter enables in-field recharging from a boat or vehicle. Underwater visible distance is quoted at 5 metres in clear conditions, though turbidity, plankton density, and backlighting from the surface will reduce this figure in practice. Importers should note that the CRT monitor's 250 x 240 x 150 mm envelope and the camera cable length are not specified in the source material, and these dimensions affect portability and deployment depth respectively.

Shenzhena Goodwilla Electricala Co., Ltd. traces its establishment to 2003 in Shenzhen, a city within Guangdong Province that hosts one of the world's densest concentrations of electronics manufacturing. The company identifies itself as a private high-tech enterprise engaged in research and manufacture across video surveillance and video home electronics categories. Its product portfolio extends beyond the underwater camera line to encompass digital door viewers, black-and-white and colour security monitors, 2.4 GHz wireless baby monitors, vehicle rear-view systems, and mini portable CRT televisions with AM/FM radio. This breadth suggests an original design manufacturer or brand OEM model rather than exclusive focus on marine electronics.

The supplier maintains an ISO 9001:2000-certified factory covering 4,000 square metres, though the current ISO 9001:2015 transition status is not confirmed in the source material. Product compliance claims span CE, FCC, FDA, R&TTE, and C-TICK markings, plus adherence to the RoHS Directive on hazardous substance restriction. Export markets cited include Europe, the United States, Asia, the Middle East, Africa, and Australia. The trust tier is listed as harbour. The response rate is zero percent with zero average response hours, which may reflect a legacy account, a change in trading entity, or a platform listing that has not been actively managed. Buyers should independently verify the company's current operational status, request a copy of the ISO certificate with valid scope, and confirm that the named compliance marks are supported by accredited test reports for the specific SKU being purchased.
