WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both WiFi and PoE at same time. While 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 whole IP camera system, you should analysis the installation environment and research which functions you want to attain.
Wireless or PoE, which is the greatest? As a older technician who have four years in video monitoring industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transmit data through cellular indication (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera facilitates Wireless, the camera can hook up your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is the advantage of Wireless.
But there are two downsides on WiFi, which are; every gadgets require power supply, that means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP cameras have the ability to operate with battery power.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have many things to consider including vitality rate of WiFi device, environment (indoor or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters indoors.
When WiFi devices are working outdoor without barrier, the transmission distance will be much much.
To increase the Wireless coverage or distance, you can set up WiFi gain access to point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 legs) indoors and a larger 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 (Cat5/6) is the primary feature of PoE technology.
As long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP cameras support plug-and-play set up, which greatly reduced the installation procedures, and eliminate the necessity of electric power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum electric power rate is to 15.4 W of DC electricity (minimum amount 44V DC and 350mA) to each device.
To be able to provide power supply for high electricity intake 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 electric power.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Downsides AND Positives 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 tv, no need extra ability cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable television, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electric power 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 than a traditional network transition, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wi-fi IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is recommended. PoE is much reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to manage, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I came across that Wireless IP surveillance cameras are trusted for non-professional indoors home security, and PoE IP surveillance cameras are installed for outdoor security system. But if you choose WiFi IP Camera please read article below.
So how does one determine which cellular IP camera suits your preferences?
Firstly, establish what you need. Many potential buyers often don't really know which kind of cellular IP camera suites and would meet their needs. Because of this, they get sucked into buying cellular 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 excellent); what perfection of data would you like to capture? (HD images with or without sound) and most importantly, what's your budget?
Second of all, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Certainly, this feature will rely upon the environment where you would like to use the camera.
A broad pan and tilt range is never a poor thing.
Thirdly, zooming capacity for the cellular IP camera is also vital.
Ensure that you check the type of zooming capability, whether its optical or digital.
Most of the IP cameras on the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the equipment before purchase.
That is vital, especially when you are buying from your local electronic store.
Always obtain a test set up as this will allow you to determine the picture quality of the camera.
In addition, it will offer you an chance to learn how to create the equipment in a proper manner to make certain you have the best image and audio tracks quality.
