WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both WiFi and PoE at same time. If 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 set up environment and investigate which functions you want to attain.
WiFi or PoE, which is a good? As a older technician who may have four years in training video 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 transfer data through cordless sign (2.4GHz UHF music group, 5GHz SHF strap).
Obviously, after the IP camera supports Wi-fi, the camera can connect your router without needing hardwired connection. WiFi can enable IP camera become portable, this is actually the advantage of Wireless.
But there are two drawbacks on WiFi, which can be; every electronic devices require power, 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 power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does indeed Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we have many things to consider including electric power rate of WiFi device, environment (inside or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters indoor.
When Wireless devices are working outdoor without barrier, the transmission distance will be much much.
To extend the Wireless coverage or distance, you can set up WiFi access point. This 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 means Power over Ethernet, this is not a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over sole Ethernet cable television (Kitten5/6) is the main feature of PoE technology.
As long as your IP camera supports PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP video cameras support plug-and-play installation, which greatly reduced the unit installation procedures, and get rid of the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum power rate is to 15.4 W of DC vitality (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high vitality consumption 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 power.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Negatives AND PROS OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired wire, there is absolutely no signal disturbance, no indication 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 a lot expensive than a traditional network switch, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Ensuring the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is preferred. PoE is much reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I found that Wi-fi IP video cameras are widely used for non-professional indoor home security, and PoE IP cameras 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 preferences?
Firstly, establish the thing you need. Many potential buyers often don't really know which type of cordless IP camera suites and would meet their needs. As a result, they get sucked into buying wireless 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 located in? (Hallway, outdoor, low light or glowing); what detail of data do you want to take? (HD images with or without audio) and most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Obviously, this feature will rely upon the surroundings where you intend to use the camera.
A wide pan and tilt range is never an undesirable thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Make sure that you check the type of zooming capabilities, whether its optical or digital.
A lot 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 electronic digital store.
Always obtain a test set up as this will enable you to look for the picture quality of the camera.
Furthermore, it will offer you an opportunity to learn how to create the equipment in a proper manner to make sure that you receive the best image and audio quality.
