WIFI OR PoE FOR IP CAMERA, WHICH MAY BE 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. After you connect the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the set up environment and research which functions you want to accomplish.
Wi-fi or PoE, which is the foremost? As a older technician who may have four years in video recording monitoring industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through wireless indication (2.4GHz UHF group, 5GHz SHF band).
Obviously, after the IP camera supports Wireless, the camera can hook up your router without needing hardwired connection. Wireless can enable IP camera become portable, this is the advantage of WiFi.
But there are two downsides on WiFi, which are; every electronic devices require power supply, that means your IP camera still requires cable television 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.
How far 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 (in house or outdoor) and much more.
Typically, a home/office router (TP-Link) can offer WiFi coverage extends to up to 10 meters inside.
When Wi-fi devices are working outdoor without barrier, the transmitting distance will be much far.
To extend the Wi-fi coverage or distance, you can install WiFi access point. This gain access to point (or hotspot) has a range around 20 meters (66 ft) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over one Ethernet cable television (Pet cat5/6) is the primary feature of PoE technology.
As long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play unit installation, which greatly reduced the assembly 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 electricity rate is to 15.4 W of DC electric power (minimal 44V DC and 350mA) to each device.
To be able to provide power for high electric power ingestion devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electricity.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Drawbacks 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 cable, no need extra vitality cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable tv, there is no signal disturbance, no sign jamming.
For properly working of PoE devices, Ability 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. Wi-fi 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 WiFi IP camera.
Making sure 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 conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to control, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I came across that Wireless IP surveillance cameras are trusted for non-professional in house home security, and PoE IP cameras are installed for outdoor surveillance system. But if you select Wireless IP Camera please read article below.
So how do you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which type of cellular IP camera suites and would gratify their needs. As a result, they get sucked into buying cellular IP video cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or bright); what detail of data do you want to capture? (HD images with or without music) and most importantly, what's your budget?
Subsequently, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Obviously, this feature will be based upon the surroundings where you intend to use the camera.
A wide pan and tilt range is never a terrible thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Ensure that you check the type of zooming ability, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never fail to find one with optical move.
Fourth, test the equipment before purchase.
This is vital, particularly when you are buying from your local electronic store.
Always request for a test installation as this will permit you to determine the display quality of the camera.
In addition, it will offer you an possibility to learn how to create the equipment in a proper manner to ensure that you obtain the best image and music quality.
