WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wireless and PoE at same time. If you connect the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the unit installation environment and research which functions you want to achieve.
Wireless or PoE, which is the foremost? As a senior technician who may have four years in video recording surveillance industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cellular signal (2.4GHz UHF music group, 5GHz SHF group).
Obviously, after the IP camera facilitates Wireless, the camera can hook up your router without needing hardwired connection. WiFi can permit IP camera become portable, this is actually the advantage of Wireless.
But there are two downsides on WiFi, that are; every electronic devices require power supply, that means your IP camera still requires cable tv for connection.
Up to now, I haven't found any IP video cameras are able to operate with batteries.
#3. WHAT LENGTHS Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've many things to consider including electricity rate of Wi-fi device, environment (indoor or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage grows to up to 10 meters indoors.
When Wi-fi devices will work outdoor without barrier, the transmission distance will be much considerably.
To increase the Wi-fi coverage or distance, you can install WiFi access point. This gain access to point (or hotspot) has a range around 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over one Ethernet cable connection (Pet cat5/6) is the main feature of PoE technology.
As long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP cameras support plug-and-play unit installation, which greatly reduced the installation procedures, and eliminate the necessity of electric power cable and offer.
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 electricity (minimum 44V DC and 350mA) to each device.
In order to provide power for high electric power ingestion 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 electric power.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Disadvantages AND Positives OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable tv, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network move, which increased a little on cost.
#6. Wi-fi 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 Wi-fi IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is preferred. PoE is a lot reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I came across that WiFi IP video cameras are trusted for non-professional inside security, and PoE IP cameras are installed for outdoor monitoring system. But if you choose Wireless IP Camera please read article below.
So how would you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many buyers often don't really know which type of cellular IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cordless IP camcorders that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or smart); what precision of data would you like to take? (HD images with or without audio) and most importantly, what is your budget?
Second of all, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Of course, this feature will depend on the surroundings where you want to use the camera.
A wide skillet and tilt range is never a bad thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the sort of zooming potential, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never fail to find one with optical zoom.
Fourth, test the equipment before purchase.
This is vital, especially when you are buying from your local electronic store.
Always obtain a test setup as this will enable you to look for the display quality of the camera.
Furthermore, it will offer you an possibility to learn how to create the gear in a proper manner to make certain you have the best image and sound quality.
