WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both WiFi and PoE at same time. Once you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the set up environment and research which functions you want to attain.
WiFi or PoE, which is the foremost? As a older technician who has four years in video monitoring industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cordless transmission (2.4GHz UHF group, 5GHz SHF band).
Obviously, once the IP camera supports Wireless, the camera can connect your router without using hardwired connection. WiFi can permit IP camera become lightweight, this is actually the advantage of Wi-fi.
But there are two downsides on WiFi, which can be; every gadgets require power, that means your IP camera still requires cable tv for connection.
So far, I haven't found any IP camcorders are able to operate with battery power.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does indeed Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including electric power rate of Wireless device, environment (indoors or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters in house.
When WiFi devices will work outdoor without barrier, the transmission distance will be much far.
To increase the Wireless coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a range around 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over single Ethernet cable television (Pet cat5/6) is the primary feature of PoE technology.
So long as your IP camera supports PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP cameras support plug-and-play set up, which greatly reduced the assembly procedures, and get rid of the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum power rate is to 15.4 W of DC ability (lowest 44V DC and 350mA) to each device.
In order to provide power for high power ingestion devices, the IEEE connection made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Negatives AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra electric power cable or power.
The maximum interconnection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable connection, there is no signal interference, no sign jamming.
For properly working of PoE devices, Electricity sourcing equipment (PSE) is essential component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive than a traditional network swap, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Ensuring the WiFi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than WiFi in terms of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to manage, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of surveillance market, I found that WiFi IP camcorders are widely used for non-professional interior security, and PoE IP camcorders are installed for outdoor monitoring system. But if you select WiFi IP Camera please read article below.
So how will you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many customers often don't really know which kind of cordless IP camera suites and would fulfill their needs. As a result, they get sucked into buying cordless IP surveillance cameras that are beyond what they need.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be situated in? (Hallway, outdoor, low light or excellent); what detail of data do you want to record? (HD images with or without audio) & most importantly, what is your budget?
Secondly, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Needless to say, this feature will rely upon the environment where you intend to use the camera.
A wide skillet and tilt range is never an awful thing.
Thirdly, zooming capability of the wireless IP camera is also vital.
Make sure that you check the sort of zooming capabilities, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never neglect to find one with optical move.
Fourth, test the equipment before purchase.
That is vital, especially when you are buying from your neighborhood electronic store.
Always request for a test set up as this will enable you to look for the display quality of the camera.
Furthermore, it will give you an chance to learn how to set up the equipment in an effective manner to make sure that you obtain the best image and audio quality.
