WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. Once you connect the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and investigate which functions you want to accomplish.
WiFi or PoE, which is best? As a senior technician who have four years in video surveillance industry, my answer 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 cordless indication (2.4GHz UHF strap, 5GHz SHF music group).
Obviously, after the IP camera facilitates 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 Wireless.
But there are two drawbacks on WiFi, that are; every electronic devices require power supply, that means your IP camera still requires cable for connection.
Up to now, I haven't found any IP surveillance cameras are able to operate with power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting 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 many things to consider including ability rate of Wi-fi device, environment (indoor or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage grows to up to 10 meters indoors.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much way.
To increase the WiFi coverage or distance, you can install WiFi gain access to point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 foot) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solitary Ethernet cable connection (Kitty5/6) is the main feature of PoE technology.
So long as your IP camera helps PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP video cameras support plug-and-play set up, which greatly reduced the unit installation procedures, and get rid of the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum ability rate is to 15.4 W of DC ability (bare minimum 44V DC and 350mA) to each device.
In order to provide power supply for high electricity utilization 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 power.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Disadvantages AND PROS OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable, there is absolutely no signal interference, no indication 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 a lot expensive when compared to a traditional network transition, which increased a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to deal with, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of security market, I came across that WiFi IP camcorders are widely used for non-professional interior security, and PoE IP video cameras are installed for outdoor security system. But if you choose Wi-fi IP Camera please read article below.
So how will you determine which wireless IP camera suits your preferences?
Firstly, establish the thing you need. Many purchasers 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 wireless IP cams 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 excellent); what accuracy of data do you want to get? (HD images with or without music) and most importantly, what is your budget?
Secondly, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Certainly, this feature will be based upon the surroundings where you would like to use the camera.
A wide pan and tilt range is never a negative thing.
Thirdly, zooming capability of the cordless IP camera is also vital.
Make sure that you check the kind of zooming functionality, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the gear before purchase.
This is vital, in particular when you are buying from your neighborhood electronic store.
Always obtain a test set up as this will permit you to look for the display quality of the camera.
In addition, it will offer you an possibility to learn how to set up the equipment in a proper manner to make certain you have the best image and audio tracks quality.
