The BNC to RCA adapter is designed to connect the RCA cable to the BNC socket devices. These devices can be video surveillance cameras, video recorders, and other video signal transmission and processing devices.
It is also possible to use the bnc to rca adapter not for its intended purpose, but in many other cases. The BNC adapter is more common in professional devices, and the RCA connector is more adjusted for household devices. Both adapters are used to transmit analog composite video signals and are compatible with each other.
For example, the adapter can be used for the test connection of a video surveillance camera with an RCA connector (at the output) directly, without connection with an extension cable, to modern video recorders or video capture cards with BNC connectors (at the input).
Or vice versa, a camera with a BNC output can be connected to a TV with this adapter and a regular RCA cable (extension cable), which always has an RCA input jack. Such adapters by Beetronics Inc. are easy to use. You won’t need extra tools to make the connection. The adapters are also made from chromed metal.

What is a BNC connector?
The BNC connector is an optional accessory designed to connect a coaxial cable. Such connections are used for connecting amateur radio, test, and aviation equipment, as well as for signal transmission in analog and digital video. This makes the equipment an indispensable solution when using analog or hybrid video surveillance.
Together with the BNC connector, it is possible to create computer networks using the 10BASE2 standard, as well as when connecting radio electronic devices. Quite actively used for use in a recording studio, connecting recording devices of various classes. If it is necessary to work with high-frequency equipment, then BNC connectors will be irrelevant, TNC is used. Consider in more detail the varieties and features of the BNC connector.
The BNC to RCA adapter characteristics
The BNC to RCA adapter by Beetronics Inc. is specially created for the installation of video surveillance systems. Now, the BNC-RCA adapter is used to connect a video camera or DVR to the TV, or as an adapter in the audio system of the DVR. It is used to transmit audio and video signals, where the petals are part of the signal «minus», and the middle is «plus».
The standard RCA plug looks like a central metal connector with a diameter of 3.2mm, which protrudes forward, with an external open length of 9.0mm, where 6.0mm occupies an internal closed length. Also, the standard RCA plug is surrounded by a metal round rim, the minimum inner diameter of which is 8.0mm.
The RCA socket is usually a connector on which to put the bezel, where 8.0mm is the outer diameter of this connector and 7.5mm is hemoglobin.
When installing the video surveillance system to connect the cable to one of the devices, you must use the BNC-RCA adapter. The RCA connector is mounted on the device and the BNC connector is on the coaxial cable. This adapter will simplify the installation of the video system and, if necessary, will facilitate the diagnostic process.
It is also possible to divide BNC connectors by type of attachment:
1. The BNC connector for the screw
This model fixes the central core of the cable with the help of a special screw and with the help of a braiding clamp in a specially designed holder. The central core and the braiding shall not contact each other.
2. BNC connector with terminal block
Such a connector features maximum ease of operation. It is also extremely simple to install. You just have to install the braid in minus, and the central core in plus. The only drawback of such connectors is the lack of a spring holder, Therefore it will not be possible to effectively use the cable. This helps to optimize the use of such an adapter on the camera sides in the junction box. If you put a recorder next to it, it’s gonna go haywire.
3. Connector BNC for crimping
This is the best way to connect with a coaxial cable. The central core is installed in a brass core, and on top is put a crimping cap, and all this will be combined with the body of the connector and squeezed with a specially designed tool.
4. Connectors BNC for soldering
They are the best option for soldering. They are characterized by increased reliability. As for reliability, they resemble a connector under the screw, but the central core will solder to the core. The braid is soldered or clamped. One of the key drawbacks is that they will be uncomfortable to mount, not height.
5. Wrapped BNC connectors
They are usually used for TV cables because their thickness and stiffness allow you to securely fix the connector. The connection is as stable, reliable, and efficient as possible from rattling.
Cables and wires for video surveillance
There are almost no specialized cables for video surveillance. All I can say is that KBK is combined coaxial with WBC wire in two versions:
- 0.5 mm2 cross section;
- and 0.75 mm2.
Thus, the selection criteria are the core section and the insulation material. The latter is critical when using a strip. The cable shall have an appropriate temperature range and an outer layer of UV-resistant insulation.
It is possible to say which cable is not recommended. These are CSIP (for alarm systems) and a twisted pair (for computer networks). The power supply of IP cameras by twisted pair is possible using PoE technology.
In this case, a switch or separate PoE injector is used instead of the BP.
Due to the relatively high rated voltage (48 V) on the twisted pair. In this case, the voltage drop is acceptable, despite the small section of the conductor.
Summing it up
Adapters and connectors are used in intrusion alarms and video surveillance systems everywhere. The usual adhesions and twists have almost completely disappeared, thanks to ready-made solutions. The use of adapters allows you to reduce the number of actions, save time and preserve the integrity of connecting wires. In addition, modern technology uses new connectors. It is not uncommon for old systems to have to invent something unusual, the use of standard adapters allows you to minimize the search for alternative solutions and take advantage of ready and reliable solutions.
