what is the working/quality of 720p wifi p2p ip/network camera ?

 When searching or browsing IP cameras in these platforms, you will realize that many suppliers sell same cameras that deliver 720p high definition video. These cameras are very cheap. 

Tentronix choose a popular 720p pan/tilt network camera,.  Name - "P2P IP/Network Camera"

Simple Installation, App works properly

This camera includes simple accessories, installation is quick. However, you need to buy an extra LAN cable for connection. Additionally, the RJ45 port designed in properly, it's not easy to unplug the LAN cable from RJ45 port.

Following the included instruction. We have tested Android, Web interface, all of them work properly. Their interfaces are also user-friendly.

Image Quality is basically good

We tested the imaging performance via PC client software, the video parameter is 720p@20fps, 2Mbps. PC client software interface is simple and user-friendly, all menu can function.

Resolution: Put camera aim at resolution testing card, after focus tuning, the camera's horizontal and vertical resolution can reach 700TVL, edge resolution is 600TVL. In home video surveillance applications, this image resolution is sufficient.

.Color Reproduction and Grayscale: Using 24 colors reproduction testing card, we can find this camera can reproduce color accurately, basically no color cast, but image is distorted severely. In grey scale testing, we find that this camera can recognize 16 level greyscale.

Real video scene: Put the camera aim at outdoor traffic road, we can find image resolution is slightly poor, scene contrast is just so so, but colors are vivid. The video frame rate is 20fps, although there is a setting to change in web interface, but you can't change frame rate.

Good pan & tilt rotation performance

This camera supports  110 degree tilt rotation, also rotation speed can be modified .

This camera supports 16 presets, preset setting is quite easy. Just making the camera rotate to a certain angle, then enter a preset number. After we make the camera rotate to different preset positions, we find that its rotation is quite precise. 

Motion detection works 

Review:

In a nutshell, this cheap P2P network camera can deliver 720p video with good quality, installation is quite simple, Pan and Tilt rotation and presets are convenient to use. The PC client software, web interface, smartphone Apps work properly.

HOW TO DECIDE WHICH IS RIGHT POWER SUPPLY FOR CCTV SECURITY CAMERA?

For ensuring the stability and reliability of your video surveillance system, installers and users should choose high quality power supply. Poor quality power supply can lead to image distortion, flickering, even damage of security camera hardware. Typically,

 outdoor security cameras utilize: 12V DC power supply, 
 PTZ cameras use: 24V AC power supply, 
some security cameras may use : 220V AC power, 
5V DC power supply is widely used in indoor security cameras. 

POWER ADAPTERS OR DISTRIBUTION BOXES?

All security cameras require some sort of power source. Power distribution boxes and power adapters are used in most installations of security cameras. If installing 4 cameras or less, most installers will choose to use a power adapter and splitter whereas installations involving more cameras, they will use a power distribution box. When choosing a power adapter, be sure to get one that supports the voltage  for your cameras.

SECURITY CAMERA SUPPORTS BOTH DC12V/AC24V, HOW TO SELECT POWER SUPPLY ?

Selecting the AC24V power supply, because in the same transmission distance, the higher voltage, the lower of consumption. High voltage can allow camera to get sufficient power supply. Meanwhile, using AC 24V, when debugging security cameras, you can choose sync power supply, this can sync image vertical frequency across different devices.

HOW MUCH POWER IS REQUIRED BY CCTV CAMERAS?

This question is difficult to answer for those inexperienced installers, many of them find the power capacity isn't sufficient in real installation, they have to increase additional power supply. Actually, the security camera needs large current when it firstly boots, plus the transmission consumption, therefore, to calculate total required power supply, doesn't mean you simply add rated power of each cameras together. The correct method is adding the rated power, then multiply 1.3, the result is the real required power supply for security cameras, additionally you need to consider the cable power consumption and power budget.

An example:

If we install 100 units security cameras in a commercial building, the rated power consumption is 4W for the security camera. How to calculate the required power supply?

• Security camera power consumption: 4W x 100 units x 1.3 = 520W
• After the consumption, the needed power rating: 520W x 1.3 = 676W
• Cable consumption and power budget: 676W x 1.3 = 878W

WHAT SHOULD BE AVOIDED WHEN SETTING UP POWER SUPPLY?

Users should avoid to use one power supply source. The reason as below:

1) When turn on/off power supply to repair video camera system. All security cameras start to boot, the required boot current is huge, this will has great impact to power supply, may lead to damage the power supply.

2) If all the security cameras use a single power supply. Once the power supply encounters problem, the whole video security cameras will turn off.

 OTHER PROBLEMS WHICH YOU HAVE PAY ATTENTION TO?

1) When connect security cameras to power supply, don't connect long distance connected security cameras and near distance connected security cameras to the same power supply. If connected to the same power supply, once power supply voltage is too high, will damage near distance connected security cameras, once power supply voltage is too low, long distance connected cameras will not work. All the near distance connected security cameras should connect to one power supply, and all the long distance connected security cameras should connect to another power supply.

2) If the installation distance of security cameras is too far, users may use higher voltage power supply, such as 30V, 36V, 48V etc, even use 220V AC power supply.

SECURE YOUR BANKS WITH IP SURVEILLANCE SYSTEM

HOW TO secure BANKS with ip surveillance?

Banking industry is one of core market sectors in video surveillance industry. Banks need high grade video surveillance systems to monitor their transaction offices and branches. IP technology is today's trend. Many new security installers really want to know how to setup/design IP video surveillance systems for bank. As the leading video surveillance products manufacturer, TENTRONIX is willing to provide you high definition network cameras and NVRs come with new technologies, meet the requirements of professional and reliable bank video surveillance solutions.

Generally, a typical network video surveillance system consists of network cameras and NVRs, as well as network switches (or PoE switches). Because this system relies on network to transmit data, so basically designing the IP video surveillance system is similar to hierarchical network topological routing. Since Power over Ethernet technology prevails in IP video surveillance solutions,we highly recommend our users to choose network equipment supports PoE. PoE can bring the users many benefits from both a network efficiency standpoint as well as a cost standpoint. With PoE, the constraint of having AC power outlets is eliminated, and centralized power management can be achieved.

BANK SECURITY SOLUTION CHALLENGES

MEGAPIXEL IMAGE QUALITY

Commercial users now require megapixel cameras support full HD 1080p video resolution, also can provide sufficient reliability for long-term operation. Additionally, network cameras must can withstand extreme weather conditions to support different kinds of environments and applications: water-resistant, vandalism, indoor and outdoor, extreme low temperature, etc.

SYSTEM SCALABILITY

Usually, bank security requires a distributed structure with centralized management. And the solution has to be scalable, allowing users to increase the number of network cameras at individual locations or expand the coverage of the solution to include even more locations.

SYSTEM RELIABILITY

Reliability is the big concern to bank security solution, and this kind of solution must has the feasibility of setting up a truly IP video monitoring solution that allows simple installation and free-maintenance. Project installers are well aware of the impact on system performance and stability generated by the large bandwidth required by megapixel video streams.
