RJ to BNC adapter, saves time.,
Verified Purchase(What's this?)
This review is from: Revo America RJ To BNC Camera System Coupler : Simple and Quick Adapter (RRJBNCCOUP) (Electronics)
I purchased these couplers to save myself the agony of pulling and replacing all the old Cat3 cables from an old security camera set-up in a hotel. The new Q-See system uses BNC and 1/4" power connectors. The adapters allowed me to attach the new cameras to the existing Cat3 cable, and attach the Cat3 cables to the DVR. Works great. A bit of advise: You'll have to make an additional adapter to connect the camera power to this adapter, because the gender of the power connector is the same as the camera's. Not an issue on the DVR side. Also, the Cat3 connector block isn't the tightest in the world, so I wrapped everything in electrical tape to ensure a solid, long lasting connection, and to ward against anyone easily tampering with it (even though the connections are hidden in the ceiling).
