WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wi-fi and PoE at same time. While you connect the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the installation environment and check out which functions you want to achieve.
WiFi or PoE, which is a good? As a mature technician who have four years in video monitoring industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transfer data through wireless transmission (2.4GHz UHF band, 5GHz SHF group).
Obviously, after the IP camera supports WiFi, the camera can connect your router without needing hardwired connection. Wireless can enable IP camera become portable, this is the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every electronic devices require power supply, that means your IP camera still requires wire for connection.
So far, I haven't found any IP cameras are able to operate with electric batteries.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've many things to consider including power rate of WiFi device, environment (indoor or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters in house.
When Wi-fi devices are working outdoor without hurdle, the transmission distance will be much way.
To increase the Wireless coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a variety around 20 meters (66 toes) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable television (Feline5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play installation, which greatly reduced the installation procedures, and get rid of the necessity of electric power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electricity rate is to 15.4 W of DC power (bare minimum 44V DC and 350mA) to each device.
To be able to provide power supply for high vitality ingestion devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Negative aspects AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra ability cable or power.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable tv, there is absolutely no signal disturbance, no sign jamming.
For properly working of PoE devices, Ability 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 when compared to a traditional network transition, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use WiFi IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is much reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to control, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I came across that Wireless IP video cameras are widely used for non-professional indoor home security, and PoE IP cameras are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how can you determine which cordless 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 satisfy their needs. Because of this, they get sucked into buying cordless IP 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 smart); what detail of data would you like to catch? (HD images with or without sound) & most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Obviously, this feature will depend on the environment where you intend to use the camera.
A wide pan and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cellular IP camera is also vital.
Ensure that you check the kind of zooming ability, whether its optical or digital.
Most of the IP cameras on the market are digital, but you'll never fail to find one with optical move.
Fourth, test the gear before purchase.
That is vital, specially when you are buying from your neighborhood electronic digital store.
Always obtain a test setup as this will allow you to look for the picture quality of the camera.
In addition, it will offer you an possibility to learn how to create the gear in a proper manner to make certain you receive the best image and music quality.
