Wired streaming: use an HDMI cable or adapter to connect the camera to the projector

Streaming live surveillance camera footage to a projector can be done in a variety of ways, one of the most reliable being a wired connection using an HDMI cable or adapter. Here's a detailed guide on how to do it:

First, you need to determine the type of cable you will need. This depends on the ports available on your camera and projector. Most digital cameras have a mini HDMI port, which is smaller than the standard HDMI port found on projectors and other devices. So, you will likely need a Mini HDMI to HDMI cable, which has one end with a mini HDMI connector and the other end with a standard HDMI connector.

Once you have the correct cable, follow these steps:

• Connect the mini HDMI end of the cable to your camera. On standard cameras, this port is usually on the left side of the camera with the screen unfolded. On pro cameras, it may be in a compartment to the right of the camera, underneath the grip.
• Connect the standard HDMI end of the cable to the projector's HDMI input port.
• Power up your camera and projector.
• Turn on the projector and wait a few moments for it to warm up and the lamp to brighten.
• Adjust your camera settings to turn off the graphical overlay so that only the live feed is projected. For standard cameras, this can usually be done by accessing the 'Other Settings' menu and turning off 'Output Onscreen Displays'. For pro cameras, you may need to access the menu through a 'FUNC' button and then turn off 'Output Onscreen Displays'.
• Adjust your projected image as needed. Use the focus ring on the projector to make the image sharper. If you need more space between the projector and the projection surface, you can adjust the zoom using the zoom ring. You can also re-orient the image using the top and bottom buttons if it appears squashed or needs to be flipped.

If your surveillance camera does not have a mini HDMI port, you may need to use an adapter. For example, if your camera has a VGA port, you can use an HDMI-to-VGA adapter along with your HDMI cable. Connect the HDMI cable to the adapter, and then connect the VGA end to your camera and the HDMI end to the projector.

Using an HDMI cable provides a reliable and direct way to stream live from your surveillance camera to a projector. It ensures low latency and high-quality video transmission without the need for a wireless connection or additional devices.

Use a laptop as an intermediary device: connect the camera to the laptop, and the laptop to the projector
