Product Description
Two Wire Main Unit (DS-KD8003-IME2-grade-C) — spec-first overview
This is a two-wire door station main unit, taking power and network over a single two-pin wire pair rather than requiring separate PoE cabling — useful on retrofits where conduit space is limited.
Key specs
- Two-pin wire carries both power supply and network access
- Built-in access control function
- Noise suppression and echo cancellation for cleaner two-way audio
- H.264 video compression for the video stream
- Low illumination performance for dim entryway conditions
- Tampering alarm for anti-vandal monitoring
- Fisheye camera with IR supplement light for wide-angle night coverage
- Supports connection of sub-modules, maximum of 8
- Nametag customisation on the panel
Installation note
Because power and data ride on the same two-core wire run, cable quality and length matter more than on standard PoE runs — a weak feed or an over-length run can cause voltage drop, which on IR-equipped units typically shows up as flickering or a black image once the IR supplement light draws extra current at night. Verify cable spec against the run length before commissioning.
Compatibility
The unit supports up to 8 sub-modules, so plan module count against this ceiling at design stage. No cross-generation part-number compatibility is specified for this SKU, so pair it only with confirmed matching sub-modules.
