Power Line Communication Camera

Power Line Communication (PLC) Camera

Power-line communication (PLC) or Ethernet over Power (EoP).carries data on a conductor that is also used simultaneously for AC electric power. Transmission or electric power distribution to consumers. It is also known as power-line carrier, power-line digital. Subscriber line (PDSL), mains communication, power-line telecommunications, or power-line networking (PLN). As we know, WiFi IP Cameras was developed to reduce the cabling costs.
However, WiFi technology has its shortage. Such as low stability, limited transmission distance, Interference problem, big bandwidth consumption etc. All these shortage are no longer exists on our PLC Security Systems. With PLC technology applied in our IP Cameras and NVR, we have cracked the main pain points for Home Security Surveillance Systems.

The PLC Cam uses the house‘s power line like a long video cable, ensuring that no connections other than the power outlet are needed. Thus installation is particularly easy: plug the PLC Cam into the power outlet, connect the provided PLC adapter to the DSL router - you‘re done! Even while on holiday or at work: the direct Internet connection and app for Apple iPhone/iPad and Android devices makes individual monitoring possible anywhere in the world.
Power-line communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. It is also known as power-line carrier, power-line digital subscriber line (PDSL), mains communication, power-line telecommunications, or power-line networking (PLN).
A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access which is often called broadband over power lines (BPL). Most PLC technologies limit themselves to one type of wires (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically transformers prevent propagating the signal, which requires multiple technologies to form very large networks. Various data rates and frequencies are used in different situations.'

A number of difficult technical problems are common between wireless and power-line communication, notably those of spread spectrum radio signals operating in a crowded environment. Radio interference, for example, has long been a concern of amateur radio groups.
Power line can be used to shorten the wiring so that safety cameras, speed up data transfer and recording to Nas and makes mounting the camera becomes easier. If it requires more than one then the connection can power-line connected to the access point in setting exudes wifi and emit a signal with a full bar to obtain the camera so that the camera is always a constant ping without breaking or disturbance barrier wall or conflicting signals.

Advanteges:
1. PLC signal is stable and relible. Siganl is much better than Wi-Fi. No consumtion of bandwidth, no interference.
2. Transmit distance is over 300meter over powerlines. No need dedicated cabling.
3. Plug and Play, super easy operation. We changed the professional CCTV system to easy handling consumer electronics.
4. PLC signal speed is over 200Mbps, 4-ch 1080p video streams flow without 
delay.

Disadvantages:
If your home electrical wiring isn't
up to date, you might not get optimal performance from a powerline networking solution. It's not as fast as Gigabit Ethernet speeds (the fastest networking solution for home or office), but it is on par with current Wireless-N Wi-Fi networking.

Powerline networking is often touted as one of the easiest and most affordable whole-home networking solutions because you don't have to lay a lot of cable or install more wiring in your walls. However, you will still need to purchase adapters that will plug into your electrical outlets. Compared to buying multiple adapters, the price of a single wireless router might make more sense depending on what you'll be networking.

You also have to be careful to choose powerline networking adapters and accessories that use the same standard. There are three standards available from a variety of manufacturers:
HomePlug AV (available from manufacturers like Belkin, Linksys, Netgear, and ZyXEL)
UPA, which stands for Universal Powerline Association (available from D-Link, Netgear, and others)
HD-PLC, which stands for High Definition Power Line Communication (available from Panasonic)
