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 Wireless and PoE at same time. After 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 installation environment and investigate which functions you want to accomplish.
Wireless or PoE, which is the better? As a senior technician that has four years in video recording security industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through wireless indication (2.4GHz UHF strap, 5GHz SHF strap).
Obviously, once the IP camera supports Wireless, the camera can hook up your router without needing hardwired connection. Wi-fi can enable IP camera become lightweight, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, that happen to be; every gadgets require power, that means your IP camera still requires wire for connection.
So far, I haven't found any IP video cameras are able to operate with battery power.
#3. WHAT LENGTHS Does indeed WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does indeed 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 Wireless device, environment (inside or outdoor) plus more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters inside.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much far.
To increase the Wi-fi coverage or distance, you can install WiFi access point. Such an access point (or hotspot) has a range around 20 meters (66 toes) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable connection (Pet cat5/6) is the main feature of PoE technology.
As 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 cameras support plug-and-play assembly, which greatly reduced the assembly procedures, and get rid of the necessity of ability cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC power (minimal 44V DC and 350mA) to each device.
In order to provide power for high power intake devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Negative aspects AND PROS OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable television, no need extra electricity cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable, there is no signal disturbance, no transmission jamming.
For properly working of PoE devices, Electricity sourcing equipment (PSE) is essential component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive than a traditional network swap, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Ensuring the WiFi IP camera is installed within coverage of your Wi-fi 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 predicated on PoE is a lot easier to take care of, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I came across that Wi-fi IP camcorders are widely used for non-professional indoor security, and PoE IP video cameras are installed for outdoor monitoring system. But if you select WiFi IP Camera please read article below.
So how do you determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many potential buyers often don't really know which kind of wireless IP camera suites and would satisfy their needs. Because of this, they get sucked into buying cellular IP cams that are beyond what they want.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or glowing); what precision of data would you like to record? (HD images with or without audio) and most importantly, what is your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Needless to say, this feature will rely upon the environment where you would like to use the camera.
A wide pan and tilt range is never a terrible thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Ensure that you check the sort of zooming capability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never fail to find one with optical zoom.
Fourth, test the equipment before purchase.
This is vital, particularly when you are buying from your neighborhood electronic store.
Always obtain a test installation as this will enable you to look for the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to create the equipment in an effective manner to make certain you get the best image and audio tracks quality.
