WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both WiFi and PoE at same time. While you hook up the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and investigate which functions you want to achieve.
Wi-fi or PoE, which is the greatest? As a senior technician who has four years in video tutorial surveillance industry, my response to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through cordless sign (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera supports Wi-fi, the camera can hook up your router without needing hardwired connection. Wireless can permit IP camera become lightweight, this is the advantage of Wireless.
But there are two disadvantages on WiFi, that are; every gadgets require power, which means your IP camera still requires cable tv for connection.
So far, I haven't found any IP cams are able to operate with power packs.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've many things to consider including electric power rate of WiFi device, environment (indoor or outdoor) and even more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters indoors.
When Wi-fi devices are working outdoor without barrier, the transmitting distance will be much significantly.
To extend the Wireless coverage or distance, you can set up WiFi access point. Such an gain access to point (or hotspot) has a variety 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 new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable television (Pet cat5/6) is the primary feature of PoE technology.
So long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cams support plug-and-play assembly, which greatly reduced the set up procedures, and eliminate the necessity of electricity cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum vitality rate is to 15.4 W of DC power (minimum 44V DC and 350mA) to each device.
In order to provide power supply for high electricity usage devices, the IEEE association made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Drawbacks AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra power cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable television, there is no signal interference, no indication jamming.
For properly working of PoE devices, Electricity sourcing equipment (PSE) is vital component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network swap, which increased 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 choose to use Wireless IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. 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 electricity solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I came across that Wireless IP cameras are trusted for non-professional inside home security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how does one determine which cordless IP camera suits your preferences?
Firstly, establish what you need. Many customers often don't really know which kind of cordless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cellular IP cams that are beyond what they need.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or dazzling); what accuracy of data would you like to take? (HD images with or without music) and most importantly, what is your budget?
Second of all, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Certainly, this feature will be based upon the environment where you want to use the camera.
A broad skillet and tilt range is never an awful thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Ensure that you check the kind of zooming capabilities, whether its optical or digital.
Most of the IP cameras in the market are digital, but you will never fail to find one with optical move.
Fourth, test the equipment before purchase.
This is vital, specially when you are buying from your local digital store.
Always request for a test set up as this will allow you to look for the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to create the equipment in an effective manner to make sure that you find the best image and audio tracks quality.
