WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. If you connect the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the installation environment and investigate which functions you want to attain.
WiFi or PoE, which is the greatest? As a mature technician that has four years in video recording surveillance industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transfer data through cellular transmission (2.4GHz UHF band, 5GHz SHF music group).
Obviously, after the IP camera supports WiFi, the camera can hook up your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is actually the advantage of Wi-fi.
But there are two drawbacks on WiFi, which can be; every electronic devices require power, which means your IP camera still requires wire for connection.
Up to now, I haven't found any IP cameras have the ability to operate with power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far will 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 vitality rate of Wireless device, environment (indoor or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters indoor.
When Wi-fi devices are working outdoor without barrier, the transmitting distance will be much significantly.
To extend the WiFi coverage or distance, you can install WiFi access point. This access point (or hotspot) has a variety of about 20 meters (66 ft) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solo Ethernet wire (Pet cat5/6) is the main 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 assembly, which greatly reduced the installation procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum power rate is to 15.4 W of DC electric power (minimal 44V DC and 350mA) to each device.
In order to provide power for high vitality usage 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 ability.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. CONS AND Advantages 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 tv, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable tv, there is absolutely no signal disturbance, no sign jamming.
For properly working of PoE devices, Electricity sourcing equipment (PSE) is vital component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive when compared to a traditional network switch, 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 opt for WiFi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to manage, centralized electricity solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I found that Wireless IP surveillance cameras are widely used for non-professional interior home security, and PoE IP camcorders are installed for outdoor security system. But if you select WiFi IP Camera please read article below.
So how do you determine which wireless 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 satisfy their needs. Because of this, they get sucked into buying wireless IP camcorders that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or shiny); what detail of data would you like to record? (HD images with or without audio) and most importantly, what's your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Naturally, this feature will rely upon the surroundings where you want to use the camera.
A broad skillet and tilt range is never an undesirable thing.
Thirdly, zooming capacity for the wireless IP camera is also essential.
Ensure that you check the kind of zooming capabilities, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the equipment before purchase.
This is vital, in particular when you are buying from your local electronic store.
Always obtain a test installation as this will allow you to determine the picture quality of the camera.
Furthermore, it will give you an chance to learn how to set up the gear in an effective manner to make certain you receive the best image and music quality.
