WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO 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 these, either Wi-fi 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 achieve.
WiFi or PoE, which is a good? As a older technician who has four years in video security industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through wireless transmission (2.4GHz UHF strap, 5GHz SHF strap).
Obviously, after the IP camera helps WiFi, the camera can hook up your router without needing hardwired connection. WiFi can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two drawbacks on WiFi, which are; every electronic devices require power, which means your IP camera still requires cable for connection.
Up to now, I haven't found any IP camcorders are able to operate with power packs.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including power rate of Wi-fi device, environment (indoor or outdoor) and even more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters interior.
When Wireless devices are working outdoor without barrier, the transmitting distance will be much considerably.
To increase the Wireless coverage or distance, you can set up WiFi access point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 feet) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over solitary Ethernet wire (Kitten5/6) is the key feature of PoE technology.
As long as your IP camera facilitates PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cams support plug-and-play unit installation, which greatly reduced the set up procedures, and get rid of the necessity of electric power cable and offer.
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 (minimum 44V DC and 350mA) to each device.
To be able to provide power supply for high vitality usage devices, the IEEE association made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Disadvantages AND Positives OF POE TECHNOLOGY
Let's firstly discuss the features 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 transmission is through wired cable television, there is no signal disturbance, no sign jamming.
For properly working of PoE devices, Electric 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 change, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Making sure the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to control, centralized vitality solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of surveillance market, I found that Wireless IP video cameras are widely used for non-professional in house security, and PoE IP surveillance cameras are installed for outdoor security system. But if you select Wireless IP Camera please read article below.
So how will you determine which cordless IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which kind of cellular IP camera suites and would meet their needs. Because of this, 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 bright); what accuracy of data would you like to catch? (HD images with or without music) and most importantly, what's your budget?
Secondly, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Of course, this feature will be based upon the environment where you intend to use the camera.
A wide pan and tilt range is never a poor thing.
Thirdly, zooming capability of the cordless IP camera is also vital.
Ensure that you check the type of zooming functionality, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, specially when you are buying from your local electric store.
Always request for a test setup as this will permit you to look for the display quality of the camera.
Furthermore, it will offer you an opportunity to learn how to create the gear in a proper manner to make certain you find the best image and audio tracks quality.
