CCTV installations 101: connecting CCTV camera to monitor without DVR


A DVR is a standard inclusion in several security system installations due to its high memory capacity necessary for recording videos captured by CCTV cameras. Nevertheless, sometimes home and business owners opt to exclude a DVR to only display surveillance videos on a monitor. The process of connecting CCTV camera directly to a TV or monitor is easy, less time-consuming, and doesn’t require technical skills except for an understanding of the components and instructions.

Here’s a guide to take you through the installation.

What You Need

  • CCTV Camera: It’s best to opt for a traditional analog CCTV camera, technically described to have CVBS (Composite video baseband signal) technology. High-resolution analog cameras are incompatible with regular TVs unless you incorporate the AHD-to-HDMI converter.
  • Coaxial Cable: Purchase pre-made Siamese coaxial cable that allows for sending of power and video simultaneously owing to its genius construction.
  • Connectors: You require BNC connectors to attach at the ends of the coaxial cable. There are several versions of BNC connectors on the market. Power jack plug adapter connectors are necessary for power connections.
  • BNC to RNC adapter: Essential for adapting TV’s RCA input to the BNC connector when connecting your camera to the monitor.
  • Power Supply: There are several models of CCTV power supplies, with some incorporating fuses and protection boxes.


  1. Installing the CCTV camera

Install any kind of CCTV camera—dome, C-mount, bullet, PTZ, and day/night camera—on the ceiling or at the top section of the wall. Select a spot where all entries and exits can be viewed clearly when installing the camera in a room. An exterior camera should be about 10 feet high to prevent intrusion.

  1. Connecting The Coaxial Cable To The Camera

The correct BNC connection to the coaxial cable is non-negotiable. You need a wire stripper to cut through the different layers of the cable and a crimping tool to tighten the grip. Upon stripping the cable, peel back the copper shielding. Take care not to lose much copper braiding; it acts as an insulator. Having connected the cable’s core to the connector’s grab, turn the connector clockwise with the crimping tool but avoid over-tightening to prevent damage to the cable’s core. Subsequently, connect the BNC to the camera to complete the step.

  1. Powering Your Camera

Make the right connection between your camera and power supply with the incorporation of the power connector. You don’t want to damage your camera, so check the polarity (negative and positive wires) at the camera and power supply ends of the cable before powering the devices. The process is easy but you need to be cautious to avoid shorting the gadgets.

  1. Connecting Your Camera To The Monitor

So far, you have connected BNC connectors to both video ends of the coaxial cable. Use the BNC to RNC adapter to connect the coaxial cable to the female RNC input (audio and visual) of the monitor. Power your monitor and select the AV input on the screen to view live video from your CCTV camera.


You may opt to bypass the DVR during CCTV camera installation if you are not eager about storing live recordings from your cam. Connecting a security camera directly to the monitor is easy, but you need to purchase the right tools and devices as well as follow the correct procedures to make the whole process effective. With the guidance outlined above, you won’t miss a thing in your installation.
