WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wi-fi and PoE at same time. When you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the set up environment and check out which functions you want to achieve.
Wireless or PoE, which is the greatest? As a senior technician who may have four years in video surveillance industry, my response to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transmit data through cordless transmission (2.4GHz UHF group, 5GHz SHF group).
Obviously, after the IP camera helps WiFi, the camera can connect your router without needing hardwired connection. Wi-fi can allow IP camera become portable, this is actually the advantage of WiFi.
But there are two downsides on WiFi, which are; every gadgets require power supply, which means your IP camera still requires cable television for connection.
So far, I haven't found any IP camcorders have the ability to operate with battery packs.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including ability rate of WiFi device, environment (indoor or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage grows to up to 10 meters indoor.
When Wireless devices are working outdoor without hurdle, the transmitting distance will be much way.
To extend the Wireless coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a variety of about 20 meters (66 feet) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over single Ethernet cable television (Pet cat5/6) is the main feature of PoE technology.
So long as your IP camera supports 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 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 power (lowest 44V DC and 350mA) to each device.
In order to provide power for high ability usage devices, the IEEE connection 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 widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Disadvantages AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the benefits 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 Wi-fi. Since data transmitting is through wired cable connection, there is absolutely no signal interference, no sign jamming.
For properly working of PoE devices, 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 switch, 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 opt for WiFi IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to deal with, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I came across that WiFi IP surveillance cameras are trusted for non-professional inside security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you choose Wireless IP Camera please read article below.
So how would you determine which cellular 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 meet their needs. Because of this, they get sucked into buying wireless IP cams 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 bright); what accuracy of data would you like to get? (HD images with or without audio tracks) and most importantly, what's your budget?
Second of all, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Obviously, this feature will be based upon the environment where you would like to use the camera.
A wide pan 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 capability, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, especially when you are buying from your local electronic digital store.
Always request for a test set up as this will permit you to determine the display quality of the camera.
Furthermore, it will give you an chance to learn how to set up the equipment in an effective manner to make certain you have the best image and audio quality.
