Model Selection Based on Application Needs Overlooking the distinct capabilities of models like the Infrared Motion Detector with Pet Immunity PA-476 versus the Alarm Digital PIR Motion Detector PA-DG85/DG85 can lead to improper security coverage; choose the model that aligns precisely with your environment and detection requirements.
Clarify Weight Specifications for Installation A critical question to ask your supplier is how the vastly different weights—ranging from 60 kg to 600 kg—impact installation logistics and mounting infrastructure, ensuring compatibility with your facility’s structural capacity.
Negotiate System Power Requirements Insist on clear confirmation that the system power consumption does not exceed ≤ 500 mA @ 12 V DC to guarantee compatibility with your existing power supply and avoid unexpected electrical upgrades.
Payment Method Flexibility and Risk Management In practice, suppliers from China typically offer diverse payment options such as T/T, L/C, D/D, Check, and Western Union; selecting the payment type that balances transaction security with cash flow efficiency directly affects your procurement risk and financial exposure.
