How to Choose an Underwater Aquaculture Camera
Hits: 504 Time: August 29,2025
Choosing an underwater aquaculture camera requires aligning with the core needs of aquaculture scenarios (such as freshwater ponds, sea cage aquaculture, and industrial seedling rearing), focusing on the three cores of "environmental adaptability, functional practicality, and cost-effectiveness", and making a comprehensive judgment from the following five aspects to avoid blind purchases:
1. Prioritize Matching Aquaculture Scenarios to Ensure Qualified Environmental Resistance
Environmental conditions vary greatly across different aquaculture scenarios, and the basic resistance of the camera must be accurately matched:
-
Sea Cage Aquaculture: Focus on "salt corrosion resistance" and "water pressure resistance" — the camera body shell should preferably be made of 316L stainless steel or titanium alloy, with a salt spray resistance rating of over 1000 hours (to resist long-term seawater erosion); for water depths within 10 meters, choose a model with a pressure resistance of 1.5MPa; for deep-sea cages (50-meter water depth), select a model with a pressure resistance of over 5MPa. At the same time, the lens should have anti-marine organism adhesion function (such as anti-fouling coating on the surface) to prevent algae and shellfish from blocking the image.
-
Freshwater Pond Aquaculture: Emphasize "turbid water penetration" and "microbial corrosion resistance" — choose a model with a turbid water penetration depth of ≥50cm (to clearly capture residual bait at the pond bottom and fish schools), and the shell should be coated with an anti-freshwater microbial corrosion layer to prevent equipment failure caused by moss and bacterial adhesion.
-
Industrial Seedling Rearing: The core needs are "macro imaging" and "low noise" — the lens should support 4K macro shooting (to capture details of 2-3mm fry), the equipment operation noise should be ≤30 decibels to avoid disturbing sensitive seedlings, and the camera body should be compact to fit the installation space of dense seedling tanks.
2. Focus on Core Functions and Avoid "Redundant Function Premium"
Select necessary functions based on aquaculture management needs to avoid paying extra costs for useless functions:
-
Basic Essential Functions: HD imaging (1080P and above resolution, 4K is recommended for sea cage aquaculture), infrared fill light (for night monitoring, 850nm wavelength is optimal, irradiation distance ≥5 meters without affecting fish daily routines), and waterproof connectors (IP68 grade to prevent cable water ingress) — these functions are core to ensuring monitoring effectiveness and are indispensable.
-
Scenario Value-Added Functions: For sea cage aquaculture, it is recommended to choose "AI recognition for net damage" (which can automatically mark holes and tears with a response time of <10 seconds) and "remote alarm" (supporting SMS/APP push of abnormal information); for freshwater ponds, "residual bait counting" function (to assist in optimizing feeding) can be selected; for industrial seedling rearing, "automatic dead seedling recognition" (to avoid pollution spread) is necessary. There is no need to increase the budget for non-essential functions such as "multilingual interface" and "cloud storage expansion".
3. Pay Attention to Installation and Operation & Maintenance to Reduce Long-Term Usage Costs
The installation convenience and maintenance difficulty of the camera directly affect the user experience:
-
Installation Methods: For sea cage aquaculture, "hanging type + magnetic base" is recommended (easy to arrange along the net and adjust with the cage position); for freshwater ponds, "suction type" can be chosen (adsorbed on the pond wall without drilling); for industrial seedling rearing, "track type" is suitable (can move along the tank to cover multiple seedling tanks). Priority should be given to models that do not require professional construction and can be installed by one person within 30 minutes.
-
Operation & Maintenance Costs: Check the replacement difficulty and cost of vulnerable parts (such as sealing rings and cables) — the sealing ring should be made of food-grade silicone (aging-resistant with a service life of ≥2 years), and the cable should be anti-drag (tensile strength ≥50kg to avoid being broken by ocean currents in sea cage aquaculture); models supporting remote firmware upgrade (no on-site disassembly required, reducing maintenance costs) are more worthy of selection.
4. Verify Data Authenticity to Avoid "False Parameter" Traps
Some products have false parameter labels, which need to be verified through actual tests or third-party certifications:
-
Pressure Resistance and Waterproof Performance: Request third-party test reports (such as SGS certification) to confirm that the waterproof rating truly reaches IP68 (can be immersed in 1.5-meter water depth for 12 hours without water ingress), and the pressure resistance value should be 50% higher than the actual aquaculture water depth (e.g., choose a 15-meter pressure-resistant model for 10-meter water depth to leave sufficient safety margin).
-
Imaging Effect: Ask the manufacturer to provide sample images from actual aquaculture scenarios (such as turbid water ponds and night sea cages) to check if the images are clear (fish body surface details and net holes can be distinguished), and avoid only looking at parameters in laboratory environments.
5. Refer to User Cases and After-Sales Service to Ensure Long-Term Usage
-
User Cases: Prioritize brands with application cases in the same scenario — for example, in sea cage aquaculture, ask "whether there are usage cases for salmon/large yellow croaker cages" and check the usage evaluations of other farmers (such as failure rate and alarm accuracy);
-
After-Sales Service: Confirm the after-sales response time (on-site maintenance within 48 hours after failure), warranty period (core components ≥3-year warranty, lifelong maintenance service is recommended for sea cage aquaculture scenarios), to avoid aquaculture losses due to delayed after-sales service.
