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 these, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the set up environment and check out which functions you want to achieve.
WiFi or PoE, which is the foremost? As a older technician who has four years in video monitoring industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transmit data through cordless transmission (2.4GHz UHF group, 5GHz SHF group).
Obviously, once the IP camera supports Wireless, the camera can connect your router without needing hardwired connection. WiFi can permit IP camera become portable, this is the advantage of Wi-fi.
But there are two drawbacks on WiFi, that are; every gadgets require power supply, that means your IP camera still requires cable for connection.
Up to now, I haven't found any IP camcorders have the ability to operate with electric batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have a lot of things to consider including ability rate of WiFi device, environment (in house or outdoor) and much more.
Typically, a home/office router (TP-Link) provides WiFi coverage gets to up to 10 meters inside.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much very good.
To extend the Wi-fi coverage or distance, you can mount WiFi access point. This gain access to point (or hotspot) has a range around 20 meters (66 feet) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solo Ethernet cable television (Cat5/6) is the main feature of PoE technology.
So long as your IP camera facilitates PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cams support plug-and-play assembly, which greatly reduced the unit installation procedures, and get rid of the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electricity rate is to 15.4 W of DC power (minimal 44V DC and 350mA) to each device.
In order to provide power supply for high vitality usage 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 vitality.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Negatives AND Positives OF POE TECHNOLOGY
Let's firstly discuss the features 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 connection, there is no signal disturbance, no transmission jamming.
For properly working of PoE devices, Power sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network transition, which increased a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to manage, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I came across that Wi-fi IP surveillance cameras are trusted for non-professional indoors home security, and PoE IP cameras are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how will you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which kind of cordless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying wireless IP video 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 glowing); what perfection of data would you like to capture? (HD images with or without sound) & most importantly, what is your budget?
Subsequently, another essential feature to consider before sometimes 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 broad skillet and tilt range is never a terrible thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Make sure that you check the kind of zooming capability, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, especially when you are buying from your neighborhood digital store.
Always obtain a test setup as this will allow you to look for the picture quality of the camera.
In addition, it will give you an possibility to learn how to create the gear in an effective manner to make certain you have the best image and audio quality.
