WIFI OR PoE FOR IP CAMERA, WHICH MAY BE 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. While you connect the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the installation environment and research which functions you want to attain.
Wi-fi or PoE, which is the best? As a older technician who may have four years in video monitoring industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through cordless transmission (2.4GHz UHF band, 5GHz SHF strap).
Obviously, after the IP camera supports WiFi, the camera can hook up your router without using hardwired connection. Wireless can enable IP camera become lightweight, this is the advantage of Wi-fi.
But there are two downsides on WiFi, that happen to be; every electronic devices require power, that means your IP camera still requires cable for connection.
Up to now, I haven't found any IP cameras have the ability to operate with power packs.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have many things to consider including vitality rate of WiFi device, environment (inside or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters inside.
When Wireless devices are working outdoor without barrier, the transmitting distance will be much very good.
To extend the Wi-fi coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 toes) 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 connection (Kitty5/6) is the primary 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 cams support plug-and-play assembly, which greatly reduced the assembly 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 vitality 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 ability utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of power.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Drawbacks AND Advantages 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 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 no signal interference, no signal jamming.
For properly working of PoE devices, Ability 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 swap, which increased just a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Ensuring the Wireless IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than WiFi in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to control, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of surveillance market, I came across that Wi-fi IP surveillance cameras are widely used for non-professional indoor home security, and PoE IP camcorders are installed for outdoor monitoring system. But if you choose Wireless IP Camera please read article below.
So how can you determine which cellular IP camera suits your preferences?
Firstly, establish what you need. Many purchasers often don't really know which type of cellular IP camera suites and would satisfy their needs. As a result, they get sucked into buying cordless 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 situated in? (Hallway, outdoor, low light or bright); what perfection of data do you want to get? (HD images with or without sound) & most importantly, what's 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 environment where you would like to use the camera.
A wide pan and tilt range is never a bad thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Ensure that you check the kind of zooming ability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never fail to find one with optical zoom.
Fourth, test the equipment before purchase.
That is vital, particularly when you are buying from your neighborhood digital store.
Always request for a test set up as this will enable you to determine the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to set up the equipment in an effective manner to make sure that you find the best image and sound quality.
