![]() ![]() ![]() If your connection isn’t subject to interference, it will also have better bandwidth, which in turn should make features like person and vehicle detection – and the alerts they trigger – more reliable.ĭome cameras have more wide-angle distortionĪnnke’s H800 eight-channel 2TB NVR is broadly comparable to the Reolink device seen above but offered here in a pack with four of the company’s C800 dome cameras. Running one lead to each location not only gives the reliability of wired power and network but makes it easier to position cameras well out of tampering range. In either case, PoE also facilitates software updates and P2P security when using remote viewing, meaning you can be confident placing cameras wherever you choose as they’re much safer from hacking than, for example, cheap wi-fi camera multi-packs.Ĭompared to wi-fi, running ethernet cables to every location you install a camera sound sounds like hard work, but over time maintaining battery-powered cameras becomes a nuisance, especially if it’s difficult to reach the camera to charge it or swap its battery. Other cameras will connect directly to power and the internet via a router and you can access their functionality via an app, or your own choice of software. That’s why a lot of security camera systems are actually low-spec computers built with slightly different priorities when it comes to the ports (quite a lot of LAN sockets for the cameras, VGA or HDMI for the display, and a hard drive, but not too much else). ![]() Ethernet cables can carry enough power to operate a surveillance camera and it goes without saying that handling a digital video signal is no problem so long as you don’t mind using networking protocols. For simplicity of installation and operation, security cameras that use PoE technology solve a lot of problems compared to older “Siamese cables.” At the same time, they eliminate the need for regular battery charging and side-step the security and range limitations of wi-fi which modern wireless systems depend upon. ![]()
