Who is the THC-B120-MS for?

A 2MP HD-TVI bullet with a built-in microphone and 30m infrared — the budget way to add sound to a coax system. It records black-and-white at night, so it suits positions where hearing what happened matters but colour after dark doesn’t: a side gate, a garage wall, a workshop entrance, a shop rear. Audio travels down the same coax as the video. For colour at night in the same body and price bracket, the THC-B129-MS ColorVu Lite; for a discreet mount under the eaves, the THC-T220-MS turret with 40m IR.

What you’ll need with it

• A HiLook HD-TVI DVR with audio over coax to record sound — e.g. DVR-204G-M1/T, DVR-208Q-M1. On other DVRs it works as a video-only camera.
• RG59 coax + 12V power per camera, or pre-made shotgun cable.
• Remote viewing through the DVR in the free HiLookVision or Hik-Connect app.

Frequently asked questions

Does it work with my existing DVR?

Yes for video — set the output to TVI, AHD, CVI or CVBS to match. Audio needs a HiLook/Hikvision DVR with audio over coax.

Is the night vision in colour?

No, infrared. The B129-MS is the colour-at-night alternative.

Can it be used outdoors?

Yes — weatherproof metal housing.
