WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. When you connect the IP camera to your router, you have to choose one of these, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the installation environment and check out which functions you want to accomplish.
Wireless or PoE, which is a good? As a senior technician that has four years in video recording security 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 wireless signal (2.4GHz UHF music group, 5GHz SHF music group).
Obviously, after the IP camera helps WiFi, the camera can connect your router without using hardwired connection. Wireless can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, which can be; every electronic devices require power, that means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP surveillance cameras have the ability to operate with batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electric power rate of Wi-fi device, environment (in house or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters interior.
When WiFi devices will work outdoor without hurdle, the transmission distance will be much way.
To increase the Wi-fi coverage or distance, you can mount WiFi access point. Such an access point (or hotspot) has a range around 20 meters (66 foot) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over single Ethernet cable television (Kitty5/6) is the key feature of PoE technology.
So 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 assembly procedures, and eliminate the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electricity rate is to 15.4 W of DC power (minimum amount 44V DC and 350mA) to each device.
To be able to provide power supply for high ability utilization 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
- Professional devices
#5. Downsides AND Positives OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet cable television, no need extra ability 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 indication jamming.
For properly working of PoE devices, Vitality 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 a lot expensive than a traditional network turn, which increased a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use WiFi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of monitoring market, I found that Wi-fi IP video cameras are widely used for non-professional indoors home security, and PoE IP camcorders are installed for outdoor monitoring system. But if you choose WiFi 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 kind of cellular IP camera suites and would gratify their needs. Because of this, they get sucked into buying wireless 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 situated in? (Hallway, outdoor, low light or dazzling); what precision of data would you like to catch? (HD images with or without music) and most importantly, what is your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Certainly, this feature will depend on the surroundings where you want to use the camera.
A broad skillet and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cellular IP camera is also vital.
Ensure that you check the sort of zooming capabilities, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the gear before purchase.
This is vital, specially when you are buying from your local electronic digital store.
Always obtain a test installation as this will enable you to look for the picture quality of the camera.
Furthermore, it will give you an possibility to learn how to set up the gear in an effective manner to ensure that you receive the best image and audio quality.
