A wide variety of camera housing manufacturers and models are available on the market. Cameras fall into multiple categories, including indoor‑use, outdoor‑use and surveillance‑oriented types, so different criteria apply when selecting camera housings. How can we identify good‑quality, cost‑effective network camera housings that fit our requirements? Specialists from Kaimorui share practical tips below.

Methods for Identifying Housing Quality

1. Adhesion TestUse a dedicated cross‑hatch cutter to cut a grid pattern on a flat area of the product (cutting edges must penetrate down to the base material). Apply 3M Tape Model 600 to the cross‑hatched area with 2 kg of pressing force for firm adhesion. Pull the tape off steadily at a 45‑degree angle to the product surface. Repeat the test three times on the same spot. Acceptable result: no coating peeling, or coating peeling covering no more than 5 % of the cross‑hatched area.
2. Water‑resistance TestAssemble the product per standard specifications. Secure the unit and submerge it in 1‑meter‑deep water for 0.5 hours. Take it out and wipe off surface moisture. Disassemble all components and inspect internally; no water seepage shall be observed inside the housing.
3. Hardness TestApply a 500 g load to a pencil hardness tester fitted with a 2H pencil. Draw a 10‑mm test stroke across the product surface. Erase the pencil mark and check the traced area. No scratches, coating chipping or obvious scuff marks are permitted.
4. Salt‑spray TestConduct testing in compliance with GB2423 environmental‑test standards. Prepare a 5 % sodium‑chloride (NaCl) solution for the salt‑spray chamber. Set the pressure‑barrel temperature to 47 °C and the test‑chamber temperature to 35 °C. Expose the product to continuous salt‑spray for 96 hours. Pass criteria: no coating discoloration or cracking; no coating detachment in the subsequent 3M‑tape adhesion check.
5. Impact‑resistance TestSet the impact tester to a drop height of 1250 px. Place the product horizontally between the 8‑mm steel ball and the base block of the tester. Release the 1000‑g weight for free‑fall impact. Lift the weight and remove the product for inspection. No coating peeling or cracking should appear at the impact site.
6. Coating‑thickness TestMeasure coating thickness with a coating‑thickness gauge. The measured value shall fall within the range of 35 μm‑70 μm.

The above covers practical knowledge for judging network camera housing quality. We hope the information above offers you useful reference.
