WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. When you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Prior to deciding 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 the best? As a mature technician who has four years in training video security industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transmit data through cellular transmission (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera supports Wi-fi, the camera can hook up your router without needing hardwired connection. Wireless can allow IP camera become lightweight, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, which are; every gadgets require power, which means your IP camera still requires cable television for connection.
So far, I haven't found any IP camcorders are able to operate with electric batteries.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does indeed Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electric power rate of WiFi device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters in house.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much considerably.
To increase the WiFi coverage or distance, you can mount WiFi access point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 ft) 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 supply over one Ethernet cable tv (Kitty5/6) is the main 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 camcorders support plug-and-play assembly, which greatly reduced the unit installation procedures, and eliminate the necessity of 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 (lowest 44V DC and 350mA) to each device.
To be able to provide power for high electric power intake devices, the IEEE association made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. CONS AND Positives 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 electricity cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired wire, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electric 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 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 wish to install one single IP camera for home monitoring, you can opt for Wireless IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wi-fi in conditions of data transmission.
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 WiFi IP cams are widely used for non-professional in house home 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 does one determine which cordless IP camera suits your preferences?
Firstly, establish the thing 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 cordless IP video 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 shiny); what perfection of data would you like to get? (HD images with or without music) and most importantly, what's your budget?
Subsequently, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Naturally, this feature will depend on the surroundings where you intend to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Ensure that you check the sort of zooming potential, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your neighborhood digital store.
Always request for a test setup as this will allow you to determine the display quality of the camera.
Furthermore, it will offer you an chance to learn how to set up the gear in an effective manner to ensure that you have the best image and audio quality.
