Sourcing 4-Channel Twisted-Pair Video Transceiver from Telehof Electronics Instruments & Equipment (Shenzhen) Co., Ltd. - China Import Guide
Before ordering the TVT-400, verify its compatibility with your camera system and the type of UTP cables available at your installation site. Confirm that the maximum transmission distance of 1200 meters meets your project requirements, and check if the optional surge protection feature is necessary for your environment. Ensure the power supply specifications match the AC 9V / 200mA requirement to avoid operational issues.
Discuss logistics with Telehof Electronics Instruments & Equipment (Shenzhen) Co., Ltd. to confirm lead times, shipping methods, and Incoterms. Clarify whether the shipment includes both receiver and transmitter units, as these may be sold separately. Request details on packaging to ensure the units arrive in good condition, especially if they are part of a larger system deployment.
Upon delivery, inspect the TVT-400 for physical damage and test its performance with your existing camera and cable infrastructure. Verify the video signal quality at the maximum intended distance and check the LED indicators for power and video status. Request documentation such as test reports or compliance certificates for electrical safety and performance standards, as these are not provided in the listing but may be required for your project.
