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 Wireless and PoE at same time. Whenever you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the set up environment and investigate which functions you want to achieve.
WiFi or PoE, which is the best? As a senior technician who has four years in video recording surveillance industry, my response to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through cellular transmission (2.4GHz UHF music group, 5GHz SHF group).
Obviously, once the IP camera facilitates Wi-fi, the camera can hook up your router without using hardwired connection. Wi-fi can allow IP camera become portable, this is the advantage of Wireless.
But there are two downsides on WiFi, which can be; every electronic devices require power, which means your IP camera still requires cable tv for connection.
Up to now, I haven't found any IP cams are able to operate with batteries.
#3. WHAT LENGTHS Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've many things to consider including vitality 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 indoors.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much considerably.
To extend the Wireless coverage or distance, you can set up WiFi access point. Such an access 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 premiered by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable tv (Feline5/6) is the main feature of PoE technology.
As 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 enable IP cameras support plug-and-play installation, which greatly reduced the unit installation procedures, and get rid of the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC electric power (bare minimum 44V DC and 350mA) to each device.
In order to provide power for high power utilization devices, the IEEE relationship 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 Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND Positives OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable, there is no signal interference, 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 much expensive when compared to a traditional network switch, which increased just a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for WiFi IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wi-fi in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to manage, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I found that WiFi IP video cameras are widely used for non-professional interior security, and PoE IP camcorders are installed for outdoor surveillance system. But if you select Wi-fi IP Camera please read article below.
So how does one determine which cellular IP camera suits your needs?
Firstly, establish the thing you need. Many customers often don't really know which type of wireless IP camera suites and would meet their needs. As a result, they get sucked into buying cellular IP surveillance cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or dazzling); what precision of data would you like to catch? (HD images with or without audio tracks) & most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Naturally, this feature will be based upon the environment where you would like to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Ensure that you check the kind 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 equipment before purchase.
That is vital, specially when you are buying from your local electric store.
Always obtain a test installation as this will allow you to look for the display quality of the camera.
Furthermore, it will offer you an opportunity to learn how to set up the equipment in a proper manner to make sure that you get the best image and sound quality.
