WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. Whenever you hook up the IP camera to your router, you have to choose one of them, either WiFi 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 accomplish.
Wi-fi or PoE, which is the greatest? As a older technician that has four years in video recording monitoring industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transmit data through cellular transmission (2.4GHz UHF band, 5GHz SHF strap).
Obviously, after the IP camera supports Wireless, the camera can connect your router without needing hardwired connection. Wireless can allow IP camera become portable, this is the advantage of Wireless.
But there are two downsides on WiFi, which are; every electronic devices require power, that means your IP camera still requires cable for connection.
Up to now, I haven't found any IP camcorders are able to operate with electric batteries.
#3. HOW FAR DOES 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 have a lot of things to consider including power rate of WiFi device, environment (indoors or outdoor) and much more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters inside.
When WiFi devices will work outdoor without barrier, the transmission distance will be much way.
To increase 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 foot) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means 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 supply over single Ethernet cable (Feline5/6) is the main feature of PoE technology.
As long as your IP camera facilitates PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP surveillance cameras support plug-and-play installation, 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 offer maximum power rate is to 15.4 W of DC ability (bare minimum 44V DC and 350mA) to each device.
To be able to provide power for high electricity 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 trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. CONS AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable tv, there is no signal interference, no signal jamming.
For properly working of PoE devices, Electric power 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 than a traditional network move, which increased just a little on cost.
#6. Wireless 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 Wi-fi IP camera.
Making sure the WiFi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of monitoring market, I came across that WiFi IP cameras are widely used for non-professional in house security, and PoE IP cams 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 preferences?
Firstly, establish what you need. Many customers 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 cameras that are beyond what they want.
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 excellent); what precision of data would you like to record? (HD images with or without audio tracks) & most importantly, what's your budget?
Secondly, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Of course, this feature will rely upon the surroundings where you intend to use the camera.
A broad skillet and tilt range is never a bad thing.
Thirdly, zooming capability of the wireless IP camera is also essential.
Make sure that you check the type of zooming potential, 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 focus.
Fourth, test the gear before purchase.
This is vital, particularly when you are buying from your neighborhood digital store.
Always obtain a test set up as this will allow you to determine 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 ensure that you have the best image and audio tracks quality.
