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 Wi-fi and PoE at same time. Once you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the set up environment and research which functions you want to achieve.
Wi-fi or PoE, which is best? As a senior technician that has four years in video recording surveillance industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transfer data through cordless sign (2.4GHz UHF music group, 5GHz SHF group).
Obviously, after the IP camera facilitates Wi-fi, the camera can hook up your router without using hardwired connection. WiFi can enable IP camera become lightweight, this is actually the advantage of Wireless.
But there are two downsides on WiFi, that happen to be; every gadgets require power, which means your IP camera still requires cable tv 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 transmission distance is another problem.
What lengths does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've many things to consider including ability rate of WiFi device, environment (interior or outdoor) and even more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters inside.
When Wi-fi devices will work outdoor without barrier, the transmission distance will be much significantly.
To increase the WiFi coverage or distance, you can mount WiFi access 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 was launched by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable tv (Pet cat5/6) 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 camcorders support plug-and-play assembly, which greatly reduced the set up procedures, and get rid of the necessity of vitality 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 vitality (lowest 44V DC and 350mA) to each device.
In order to provide power supply for high ability intake 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 monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Negative aspects AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra power cable or power.
The maximum interconnection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable television, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, 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 much expensive when compared to a traditional network swap, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wi-fi IP camera.
Making sure the Wireless IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than WiFi in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I found that Wireless IP surveillance cameras are widely used for non-professional inside security, and PoE IP camcorders are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how does one determine which cellular IP camera suits your needs?
Firstly, establish the thing you need. Many customers often don't really know which kind of wireless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cordless IP video 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 located in? (Hallway, outdoor, low light or bright); what perfection of data do you want to take? (HD images with or without sound) and most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Of course, this feature will be based upon the environment where you intend to use the camera.
A broad pan and tilt range is never a bad thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Ensure that you check the kind of zooming capability, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never fail to find one with optical move.
Fourth, test the equipment before purchase.
This is vital, specially when you are buying from your neighborhood digital store.
Always request for a test setup as this will permit you to determine the picture quality of the camera.
Furthermore, it will offer you an opportunity to learn how to set up the gear in a proper manner to make certain you obtain the best image and audio quality.
