A:AnswerYes, the Lorex product you're looking for is wireless (Wi-Fi) and powered by A/C. It fits your description perfectly. The confusion around "POE powered" likely refers to Power over Ethernet, which is an alternative power option for some Lorex cameras. However, the product you're inquiring about operates through standard A/C power and wireless Wi-Fi connectivity, making it suitable for your needs without the complexity of POE setup.
A:AnswerNVR supports a maximum of 8 cameras. Make sure your switch has POE to power up the cameras and then you can search the network to find the cameras on the VLAN if the NVR is on the same VLAN IP subnet.
