Grandstream GDS3720 Series Accessories — Common Questions

Everything you need to know about the Grandstream GDS3720 Series Accessories before you buy.

Grandstream offers an in-wall mounting box for the GDS3725/GDS3726, a GDS3720 Series rain cover, an L-shaped bracket, NFC cards and NFC key fobs in G-AC1 and G-AD2 versions, and the GS-POE15W-MG and GS-POE30W-MG PoE injectors.
The in-wall mounting box is designed for the GDS3725 and GDS3726. It supports solid wall, stud and drywall (hollow wall) installation. Follow local building and electrical codes, and mount the device with its bottom 50–52 inches above the ground.
Both are non-writable contactless credentials powered by the NFC reader. G-AC1 versions use Mifare Classic EV1 (1KB), while G-AD2 versions use Mifare DESFire EV3 (2KB) and support the AES-128 algorithm for higher security.
Use the rain cover at exposed entrances. It helps protect GDS3720 Series door stations from harsh weather and reduces the risk of rain or snow interfering with audio and video performance.
The stainless-steel L-shaped bracket is used with GDS3700 Series door stations in flush-mounting applications, providing structural reinforcement when installing on wall studs.
The GS-POE15W-MG supports IEEE 802.3af with 20W PoE output, and the GS-POE30W-MG supports 802.3af/at with 30.2W output. Both are plug-and-play, with a built-in power adapter, 1.2 m AC cable and 2.5Gbps LAN in and PoE out ports.
