The Atlona AT-APC21-A is a VGA video and audio switch with automatic input selection. Here are some pros and cons that may help you make an informed decision about purchasing this product:

1. Automatic Input Selection: The AT-APC21-A automatically detects and switches to the active input source, making it a convenient option for environments where multiple sources need to be connected.

2. 5V Power Supply: The switch provides a 5V DC power output, which can be used to power external devices such as a PoE (Power over Ethernet) camera or an IR extender.

3. Compact Design: The AT-APC21-A has a small form factor, making it easy to install in tight spaces.

4. LED Indicators: The switch has LED indicators that indicate the selected input and power status, making it easy to troubleshoot and monitor.

5. Affordable: The AT-APC21-A is a cost-effective solution for switching between multiple VGA sources.

1. Limited Inputs and Outputs: The switch only supports one input and one output for VGA video and audio, which may not be suitable for environments that require more extensive switching capabilities.

2. No HDMI or DisplayPort Support: The AT-APC21-A only supports VGA, and does not offer HDMI or DisplayPort connectivity, which may limit its application in modern environments.

3. No RS-232 Control: The switch does not offer RS-232 control, which may be a limitation for larger installations that require remote control capabilities.

In conclusion, the Atlona AT-APC21-A is a cost-effective solution for automatic switching between multiple VGA sources with the added benefit of providing a 5V power output. However, it has limitations such as a lack of HDMI or DisplayPort support and no RS-232 control. Therefore, it may not be the best option for environments that require more extensive switching capabilities or modern connectivity options.

If you are looking for a more versatile switching solution, you may want to consider a switch with HDMI or DisplayPort connectivity, as well as RS-232 control capabilities. However, if your requirements are limited to VGA switching with a 5V power output, the AT-APC21-A may be a suitable option for you.
