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 Wireless and PoE at same time. When you connect the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the set up environment and check out which functions you want to attain.
WiFi or PoE, which is a good? As a mature technician who may have four years in video tutorial surveillance industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transmit data through cellular indication (2.4GHz UHF music group, 5GHz SHF strap).
Obviously, after the IP camera helps WiFi, the camera can hook up your router without needing hardwired connection. Wi-fi can allow IP camera become portable, this is actually the advantage of WiFi.
But there are two disadvantages on WiFi, which can be; every electronic devices require power supply, which means your IP camera still requires wire for connection.
Up to now, I haven't found any IP cameras are able to operate with battery power.
#3. HOW FAR DOES 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 WiFi device, environment (indoors or outdoor) plus more.
Typically, a home/office router (TP-Link) can provide WiFi coverage grows to up to 10 meters indoors.
When WiFi devices will work outdoor without hurdle, the transmitting distance will be much far.
To extend the Wireless coverage or distance, you can install WiFi access point. Such an gain access to point (or hotspot) has a variety around 20 meters (66 feet) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over sole Ethernet cable tv (Feline5/6) is the key feature of PoE technology.
As long as your IP camera supports PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play set up, which greatly reduced the unit installation procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum ability rate is to 15.4 W of DC vitality (minimum amount 44V DC and 350mA) to each device.
To be able to provide power for high ability use devices, the IEEE association made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP monitoring 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 features of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra vitality cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired wire, there is no signal interference, no signal 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 a lot expensive than a traditional network change, 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 opt for Wi-fi IP camera.
Guaranteeing 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 conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to deal with, centralized vitality solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I came across that WiFi IP cams are trusted for non-professional indoors home security, and PoE IP cameras are installed for outdoor surveillance system. But if you choose Wireless IP Camera please read article below.
So how would you determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many potential buyers often don't really know which type of cellular IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cordless IP cameras that are beyond what they need.
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 do you want to take? (HD images with or without audio tracks) and most importantly, what's your budget?
Subsequently, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Obviously, this feature will be based upon the surroundings where you want to use the camera.
A wide pan and tilt range is never a negative thing.
Thirdly, zooming capacity for the cellular IP camera is also vital.
Ensure that you check the type of zooming functionality, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your neighborhood electronic digital store.
Always request for a test installation as this will enable you to determine the picture quality of the camera.
In addition, it will give you an opportunity to learn how to create the gear in a proper manner to ensure that you get the best image and sound quality.
