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 Wi-fi and PoE at same time. Whenever you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the set up environment and investigate which functions you want to attain.
Wireless or PoE, which is the better? As a older technician that has four years in video recording surveillance industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cellular signal (2.4GHz UHF strap, 5GHz SHF strap).
Obviously, after the IP camera supports WiFi, the camera can hook up your router without needing hardwired connection. WiFi can permit IP camera become lightweight, this is the advantage of Wi-fi.
But there are two drawbacks on WiFi, that happen to be; every gadgets require power supply, that means your IP camera still requires cable tv for connection.
So far, I haven't found any IP cams are able to operate with electric batteries.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including ability rate of WiFi device, environment (inside or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage reaches up to 10 meters indoor.
When Wi-fi devices will work outdoor without hurdle, the transmitting distance will be much much.
To increase the Wireless coverage or distance, you can mount WiFi access point. Such an access point (or hotspot) has a variety of about 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solitary Ethernet cable television (Pet cat5/6) is the main feature of PoE technology.
So 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 enable IP cams support plug-and-play assembly, which greatly reduced the installation procedures, and eliminate the necessity of electricity cable and supply.
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 power (minimum amount 44V DC and 350mA) to each device.
In order to provide power supply for high electricity use 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 ability.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. Negative aspects AND PROS OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra electric power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable, there is absolutely no signal disturbance, no transmission jamming.
For properly working of PoE devices, Vitality sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network switch, which increased a little on cost.
#6. WIFI 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 Wireless IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is much reliable than WiFi in terms of data transmission.
Furthermore, an IP camera system based on PoE is much easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of security market, I found that WiFi IP cameras are widely used for non-professional indoor home security, and PoE IP video cameras are installed for outdoor monitoring system. But if you select Wireless IP Camera please read article below.
So how do you really determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many clients often don't really know which type of cordless IP camera suites and would gratify their needs. Because of this, they get sucked into buying cellular IP surveillance cameras that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or excellent); what accuracy of data would you like to take? (HD images with or without audio tracks) and most importantly, what's your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Naturally, this feature will depend on the surroundings where you would like to use the camera.
A wide skillet and tilt range is never a terrible thing.
Thirdly, zooming capacity for the wireless IP camera is also vital.
Ensure that you check the type of zooming capacity, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never fail to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, in particular when you are buying from your local digital store.
Always obtain a test installation as this will enable you to look for the display quality of the camera.
Furthermore, it will offer you an possibility to learn how to set up the equipment in an effective manner to make sure that you obtain the best image and music quality.
