Installed the TR-D2221WDIR4 with the 2.8 mm lens in a client’s warehouse for broad coverage. The day/night IR feature works well in low-light conditions, providing clear images. Setup was straightforward after confirming compatibility with the existing network. The camera’s wide field of view reduced the number of units needed for full coverage, which helped keep the installation efficient.
