If you need the simplest possible video surveillance solution, you can set it up yourself. We're talking about combining an inexpensive analog camera with a TV. This article covers how to connect a video camera to a TV. I'll also explain how to connect a webcam to a TV. There's a lot of useful information here.

Why Connect a TV and a Video Camera?

Connecting a camera to an existing TV mostly makes sense for everyday household use. The most common goal is monitoring the front door of an apartment or the gate at the entrance to a private home. A similar system can also be used to keep an eye on a car parked in the yard.

There's no need to buy a separate monitor or turn on a computer every time someone rings the doorbell if your TV is always on. It can easily serve as a monitor. All you need to do is switch the channel with the remote. It's that simple.

If a TV isn't part of your everyday life as a way of connecting with the outside world, this approach won't be relevant for you.

A similar system is also often used to monitor a small space with a single entrance (a construction site, an entryway, a warehouse) together with a security guard/operator.

What Equipment Can Be Connected to a TV?

For a “TV + recording device” setup, you need equipment that uses Composite Video Baseband Signal technology, or CVBS for short. In professional circles, this is simply what a standard analog video camera is called.

Analog cameras that use HD-TVI, HD-CVI, or AHD technology won't work for this (the equipment isn't compatible with a household TV set). You need a camera with technical specifications of 480, 540, 600, or 700 TV Lines.

For image quality, it's important to choose an appropriate display device. Even the most expensive camera, connected to a small, low-quality screen, will produce a blurry, unclear picture.

The Components You'll Need

How do you connect a camera to a TV? Before you get started, make sure you have the necessary components on hand, namely:

  • •          An analog-type camera and a TV
  • •          A coaxial cable (RG59). It's needed to carry power and the video signal at the same time.
  • •          A BNC connector, which can be used on both ends of the coaxial cable
  • •          A BNC-to-RCA adapter to match up the inputs
  • •          A plug adapter connector to hook up the power
  • •          A power source

Step-by-Step Connection Tutorial

Now let's get to the practical part. Follow the step-by-step tutorial below.

Step 1

Determine your monitoring goals and coverage area, and calculate the equipment's focal length using the formula. Purchase a video camera suitable for use with a TV, along with the components listed above. Don't try to save money by skimping on equipment quality or buying it on AliExpress. Here's why.

Step 2

Install the video camera in the monitoring area. Keep in mind that improper installation can ruin the system from the very start. Read the article “How to Ruin a Video Surveillance System During Installation? 6 Common Mistakes.”

Step 3

Connect the CCTV cable to the video camera. The key detail here: make sure the cable's braided shielding doesn't touch the central conductor.

Step 4

Attach the (P4) connector to power the recording equipment. Pay close attention to the cable polarity here — getting it wrong can damage the camera.

Step 5

Next, connect the power source (power supply unit) to the camera. Correct polarity matters here too. This connection should take no more than 1–2 minutes.

Step 6

Now it's time to connect the video camera to the TV. You'll need the BNC-to-RCA adapter. Then connect the camera to the TV using the standard video output (the audio/video input).

Step 7

Turn on the TV. Select “AV input” in the menu. The image from the video camera should appear on the screen. The system is now ready to use. Now you know how to connect a camera to a TV.

Is There a More Cost-Effective Alternative?

How would you feel about getting a modern video monitoring system that has minimal dependence on a power supply, at no financial cost?

Consider an alternative video surveillance setup based on the free Faceter mobile app and two smartphones. One or both phones can be old, unused devices with minimal technical requirements:

  • •          A camera of 1.3 MP or higher
  • •          3G internet access or better
  • •          A working processor, screen, and charging port

You can download the app from Google Play or the App Store, depending on your phones' operating system. For home use, select the free “Basic” plan. Set up one phone as the camera and the other will work as the monitor.

IMPORTANTLY, you won't need to:

  • •          Buy an analog camera and the components to connect it
  • •          Deal with installing the TV and the camera
  • •          Periodically update the system (it updates automatically)
  • •          Worry about data storage security (that's handled by the cloud provider)
  • •          Depend on a power supply, since the phones can be charged from a car's cigarette lighter socket or a power bank

In Lieu of a Conclusion

There's no question that combining a TV with an analog camera is a valid approach. In many cases, this type of video surveillance can be quite useful. It's especially common for monitoring a home's front door, keeping an eye on a car in the yard, and overseeing the situation at a small site. We hope this article was useful to you.
