This four pack of Axis 210A network cameras will get your security system up and running quickly. They use Sony Wfine progressive scan CCDs for exceptional image quality. They operate in illumination levels down to 1Lux so peace of mind can continue into the evening.
Power over Ethernet (802.3af) support simplifies installation by eliminating the need to run extra wires to your mounting location. This way the RJ45 cable sends power, video and audio. Audio can be either one-way with the built in microphone or two-way with an external speaker. There is also a jack for an external microphone so you can attach an intercom box.
