WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. When you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and check out which functions you want to accomplish.
Wi-fi or PoE, which is the greatest? As a mature technician who has four years in video tutorial 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 cellular signal (2.4GHz UHF strap, 5GHz SHF strap).
Obviously, after the IP camera facilitates Wireless, the camera can hook up your router without needing hardwired connection. WiFi can permit IP camera become lightweight, this is actually the advantage of Wireless.
But there are two drawbacks on WiFi, which can be; every gadgets require power supply, which means your IP camera still requires cable connection for connection.
So far, I haven't found any IP camcorders are able to operate with batteries.
#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've a lot of things to consider including electricity rate of Wi-fi device, environment (inside or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters interior.
When Wireless devices are working outdoor without barrier, the transmitting distance will be much considerably.
To extend the Wireless coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a range of about 20 meters (66 toes) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for 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 solitary Ethernet cable (Kitty5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play set up, which greatly reduced the set up procedures, and eliminate the necessity of electric power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum ability rate is to 15.4 W of DC power (lowest 44V DC and 350mA) to each device.
In order to provide power supply for high power 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 ability.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Negative aspects 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 vitality cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable, there is no signal interference, no signal jamming.
For properly working of PoE devices, Electricity 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 than a traditional network swap, which increased a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Ensuring the Wi-fi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is much reliable than Wi-fi in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to control, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of surveillance market, I found that Wireless IP cams are widely used for non-professional inside home security, and PoE IP camcorders are installed for outdoor surveillance system. But if you choose Wireless IP Camera please read article below.
So how would you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which type of wireless IP camera suites and would meet their needs. Because of this, they get sucked into buying cordless IP cameras that are beyond what they need.
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 smart); what accuracy of data do you want to catch? (HD images with or without sound) and most importantly, what is your budget?
Second, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Needless to say, this feature will depend on the environment where you would like to use the camera.
A broad pan and tilt range is never an undesirable thing.
Thirdly, zooming capability of the wireless IP camera is also essential.
Ensure that you check the kind of zooming ability, 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 zoom.
Fourth, test the equipment before purchase.
This is vital, in particular when you are buying from your neighborhood electronic digital store.
Always request for a test installation as this will allow 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 a proper manner to make sure that you get the best image and audio tracks quality.
