WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless 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 Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and investigate which functions you want to attain.
Wireless or PoE, which is best? As a older technician who have four years in training video security industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transmit data through wireless transmission (2.4GHz UHF strap, 5GHz SHF group).
Obviously, after the IP camera helps Wi-fi, the camera can connect your router without needing hardwired connection. Wi-fi can allow IP camera become portable, this is actually the advantage of Wi-fi.
But there are two downsides on WiFi, that happen to be; every gadgets require power supply, that means your IP camera still requires cable connection for connection.
So far, I haven't found any IP cameras are able to operate with battery power.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've many things to consider including power rate of Wireless device, environment (indoors or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters indoors.
When Wireless devices will work outdoor without barrier, the transmitting distance will be much way.
To extend the WiFi coverage or distance, you can mount WiFi access point. This gain access to point (or hotspot) has a range of about 20 meters (66 feet) 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 was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable television (Cat5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play assembly, which greatly reduced the assembly procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum electricity rate is to 15.4 W of DC ability (minimal 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 vitality.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Negative aspects AND PROS 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 television, no need extra vitality cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable tv, there is no signal interference, no transmission jamming.
For properly working of PoE devices, Ability 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 much expensive than a traditional network change, which increased just 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 opt for WiFi IP camera.
Guaranteeing the Wireless 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 terms of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to take care of, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I came across that WiFi IP camcorders are widely used for non-professional interior home security, and PoE IP cameras are installed for outdoor security system. But if you select Wireless IP Camera please read article below.
So how can you determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many purchasers often don't really know which kind of wireless IP camera suites and would satisfy their needs. As a result, they get sucked into buying cellular IP video cameras 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 bright); what precision of data would you like to take? (HD images with or without music) and 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 surroundings where you want to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Make sure that you check the kind of zooming capacity, whether its optical or digital.
Most of the IP cameras on the market are digital, but you'll 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 digital store.
Always request for a test set up as this will enable you to look for the picture quality of the camera.
Furthermore, it will give you an chance to learn how to create the equipment in an effective manner to ensure that you have the best image and sound quality.
