WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wireless and PoE at same time. While you hook up the IP camera to your router, you have to choose one of these, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and investigate which functions you want to accomplish.
WiFi or PoE, which is the greatest? As a mature technician who have four years in video monitoring industry, my response 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 cordless sign (2.4GHz UHF music group, 5GHz SHF group).
Obviously, after the IP camera helps Wireless, the camera can hook up your router without needing hardwired connection. Wi-fi can enable IP camera become lightweight, this is actually the advantage of WiFi.
But there are two drawbacks on WiFi, which are; every electronic devices require power supply, which means your IP camera still requires cable connection for connection.
So far, I haven't found any IP camcorders have the ability to operate with electric batteries.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths 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 power rate of Wireless device, environment (indoor or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage grows to up to 10 meters indoors.
When WiFi devices are working outdoor without barrier, the transmitting distance will be much far.
To increase the Wi-fi coverage or distance, you can mount WiFi access point. Such an gain access to point (or hotspot) has a variety 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 fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over solo Ethernet cable tv (Cat5/6) is the primary feature of PoE technology.
As long as your IP camera helps PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP video cameras support plug-and-play assembly, which greatly reduced the unit installation 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 electric power (lowest 44V DC and 350mA) to each device.
To be able to provide power for high vitality utilization 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 electricity.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Negatives AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable connection, no need extra vitality cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable connection, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Ability 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 a lot expensive than a traditional network transition, which increased a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system based on PoE is much easier to take care of, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of surveillance market, I found that Wireless IP surveillance cameras are widely used for non-professional indoors home security, and PoE IP video cameras are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many purchasers 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 surveillance cameras 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 shiny); what accuracy of data would you like to take? (HD images with or without music) & most importantly, what is your budget?
Subsequently, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Obviously, this feature will be based upon the surroundings where you want to use the camera.
A wide skillet and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the sort of zooming ability, 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.
That is vital, especially when you are buying from your local electronic store.
Always obtain a test set up as this will enable you to determine the display quality of the camera.
In addition, it will give you an opportunity to learn how to set up the equipment in a proper manner to ensure that you obtain the best image and audio quality.
