Takeaways

• 😀 This video demonstrates the installation of AHD CCTV cameras, covering both video and power connections.
• 😀 Four types of cameras are used: two turret domes (for indoor use) and two bullet cameras (for outdoor use).
• 😀 The cameras are connected to a four-channel DVR for video processing and recording.
• 😀 A 12V power supply unit is required to power all four cameras.
• 😀 The video cables used are coaxial cables fitted with BNC connectors, which connect the cameras to the DVR.
• 😀 Power cables are fitted with DC power connectors and supply power to the cameras.
• 😀 The video connection process involves connecting male BNC connectors from the camera to the DVR using coaxial cables.
• 😀 After connecting video cables for all cameras, the power cables are connected to the cameras and routed to the power supply unit.
• 😀 Power connections must be wired correctly, observing polarity (red for positive and blue for negative).
• 😀 The terminal blocks on the power supply unit are used to secure power cables for each camera, ensuring proper wiring for each one.
• 😀 Once all connections are made, the system is powered on, and the cameras will appear on the DVR screen for monitoring.

Q & A

What is the main focus of this video?

The main focus of the video is a practical demonstration of how to install AHD CCTV cameras, including how to connect both video and power cables for each camera, and how to wire the power supply unit.

What type of cameras are used in the demonstration?

The demonstration uses four AHD cameras: two turret domes for indoor use and two bullet cameras for outdoor use.

What equipment is required for this installation process?

The required equipment includes AHD cameras, a 4-channel DVR, a 12V power supply unit, coaxial cables fitted with BNC connectors, power cables with DC connectors, and CMS cables for one of the cameras.

How is video connection made between the cameras and DVR?

The video connection is made by plugging a male BNC connector into a female BNC connector at one end of the coaxial cable, and the other end is connected to the DVR.

What is the next step after connecting the video cables?

After connecting the video cables, the next step is to wire the power cables to the cameras and connect them to the power supply unit.

How do you wire the power supply for the cameras?

The power cables are plugged into the cameras. The other end of each power cable is then connected to a terminal block in the power supply unit. The red wire is connected to the positive terminal, and the blue wire is connected to the negative terminal. This is done for each camera.

Why is polarity important when wiring the power supply?

Polarity is important because the power supply cables need to be connected correctly: red to positive and blue to negative. Incorrect wiring could damage the cameras or prevent them from working properly.

What tool is used to strip the power cable insulation?

A pair of pliers is used to strip the insulation from the power cables to expose the conductors before connecting them to the power supply unit.

What is the purpose of the CMS cable in this setup?

The CMS cable is used to connect one of the cameras as a demonstration of how it is also used in the installation process. It has both video and power cables.

How do you verify that the cameras are working after the installation?

Once all the video and power connections are made, the system is powered up, and the DVR will load. When the system is ready, all cameras should be displayed on the screen, confirming that they are working properly.
