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 WiFi and PoE at same time. Once you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the unit installation environment and check out which functions you want to attain.
Wi-fi or PoE, which is the best? As a older technician who have four years in video recording security industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through cellular transmission (2.4GHz UHF band, 5GHz SHF band).
Obviously, after the IP camera helps Wi-fi, the camera can hook up your router without using hardwired connection. Wi-fi can enable IP camera become lightweight, this is the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every gadgets require power supply, which means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP surveillance cameras have the ability to operate with batteries.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmission 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 ability rate of Wi-fi device, environment (inside or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters indoors.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much much.
To increase the WiFi coverage or distance, you can install WiFi gain access to point. Such an access point (or hotspot) has a range of about 20 meters (66 foot) 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 premiered by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable connection (Feline5/6) is the key feature of PoE technology.
As long as your IP camera supports PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play 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 vitality rate is to 15.4 W of DC ability (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high electric power ingestion 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 ability.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Drawbacks AND PROS OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable tv, there is no signal interference, no indication jamming.
For properly working of PoE devices, Power sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network change, which increased a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is much reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to deal with, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I came across that Wireless IP cameras are widely used for non-professional indoor security, and PoE IP cameras are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how does one determine which cellular IP camera suits your needs?
Firstly, establish the thing you need. Many clients 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 cordless 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 situated in? (Hallway, outdoor, low light or glowing); what detail of data would you like to capture? (HD images with or without music) & most importantly, what is your budget?
Secondly, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Naturally, this feature will rely upon the environment where you want to use the camera.
A broad pan and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cordless IP camera is also essential.
Make sure that you check the kind of zooming capabilities, whether its optical or digital.
Most of the IP cameras in the market are digital, but you will never fail to find one with optical move.
Fourth, test the gear before purchase.
This is vital, in particular when you are buying from your neighborhood electronic store.
Always obtain a test setup as this will permit you to look for the display quality of the camera.
In addition, it will give you an chance to learn how to set up the gear in an effective manner to make sure that you have the best image and audio tracks quality.
