A wide variety of camera housing manufacturers and product types are available on the market. Cameras are categorized for indoor use, outdoor use, surveillance and other scenarios, which means different criteria apply when selecting camera housings. How can we identify high-quality, cost-effective housings? The specialists from Kaimorui will share practical inspection methods below.

Methods to Judge the Quality of IP Camera Housings

Pencil Hardness Test: Apply a 500g load with a 2H pencil. Perform a 10 mm scratch test on the product surface. Wipe off the pencil marks with an eraser and inspect the scratched area. No scratches, coating peeling or obvious abrasions should be observed.

Adhesion Test: Use a dedicated cross-hatch cutter to cut a grid pattern on the flat surface of the product (the blade must cut through to the base material). Apply 3M test tape (Model 600) to the grid area with 2kg pressing force for firm adhesion. Pull the tape off steadily at a 45° angle to the product surface. Repeat the test 3 times at the same location. The coating shall not peel off, or the peeled area shall be less than 5% of the grid.

Salt Spray Test: In accordance with GB2423 environmental test requirements, prepare a 5% sodium chloride (NaCl) solution and pour it into the salt spray chamber. Set the pressure tank temperature to 47°C and the cabinet temperature to 35°C. Keep the product inside the salt spray chamber for 96 hours. No coating discoloration or cracking is allowed, and no peeling shall occur in the 3M tape adhesion check after the test.

Waterproof Performance Test: Assemble the product as specified. Attach a weight and submerge the product in 1 meter deep water. Retrieve it after 0.5 hours, wipe off surface moisture, and disassemble all components. No water seepage shall be found inside the housing.

The above describes methods for evaluating IP camera housing quality. We hope this introduction is helpful for your reference.
