Camera Types
The different types of surveillance applications require security cameras with different capabilities. In addition, every user has his/her unique needs that have to be catered to by the type of cameras they select. 
Regarding the camera types, please check: Common Types of MVTEAM Security Cameras

Camera Lenses
The choice of camera lenses will determine the amount of light that a camera can focus on its security camera systems sensor in order to create an image. In addition, lenses determine the distance and viewing angle of the camera.

Camera Resolution
Resolution defines how clear the image from your camera will be. A clearly visible image is very helpful when trying to identify faces or items in the images your camera records.
For Camera resolution you can check :How many different resolution in CCTV Surveillance System?

Wired or Wireless?
Whether or not you want your security camera to be hardwired or not is another factor in your decision. Wired surveillance cameras typically send a more solid and secure video signal because they transmit via cable and not through the air, but can take more money and effort to install because wiring needs to be run. That either means hiring an installer, or buying the cable and taking the time to do it yourself.

On the other hand, wireless cameras can be placed virtually anywhere with ease, because you don’t have to worry about running new cable or patching into existing cable runs. Signal security is also becoming much less of an issue, thanks to ever-improving encryption protocols like WIFI Protected Access (WPA) and Temporal Key Integrity Protocol (TKIP).

Audio choice
Integrating audio into a surveillance system makes it possible for personnel to hear and speak with possible perpetrators. It can be easily integrated with video management systems.
From a surveillance point of view it can also be used as an independent detection method triggering recordings and alarms when audio passes a certain threshold. 

P2P allowed?
Nowadays almost all the CCTV security system come with the P2P mobile app for remote viewing. It is great development for the Security filed. That makes the system more easy and convenient for users.

MVTEAM Different system has the different app for mobile phone, more details you can check the Technical Article for DVR/NVR.

In CCTV camera system,there are many different interfaces for video signal and control signal,how long can they transfer signal?Today we talk about the transmission distance of different video signal interfaces and control signal interfaces.

A.Video Signal Interfaces
1.Composite video signal: BNC

According to the impedance can be divided into SYV 50-XX, SYV 75-XX, SYV-100 XX, ... 
XX means the outside diameter(unit: mm) of insulation layer. 
75-3 transmission distance: about 200 meters; 
75-5 transmission distance: about 500 meters; 
75-7 transmission distance: about 500 - 800 meters; 
75-9 transmission distance: about 1000 - 1500 meters; 
75-12 transmission distance: about 2000 - 3500 meters.

2.S-VIDEO transmission distance: about 15 meters.

3.VGA tansmission distance: 15-30 meters.


4.HDMI transmission distance: Max. 15 meters


5.SDI transmission distance can reach 300-500 meters, but this is only a theoretical transmission distance, generally, HD SDI transmission distance is 10-150 meters without signal loss, which is in very good cable case.


B.Control Signal Interfaces
1.RS-232: Transmission rate is low, transmission distance is 15 meters to 20 meters.

2.RS-422 has stronge anti-interference ability, can transmit 1200 meters, the maximum transmission rate is 10Mb/s.


3.RS-485: maximum communication distance is about 1219 meters, the maximum data transfer rate is about 10Mbps.

No matter HDCVI,HDTVI and AHD camera,they must match the same technology DVR.
Because dahua controled the HDCVI technology,so their DVR not support HDCVI and AHD camera,noly HDCVI camera. With the new series of HDTVI or AHD product comes out,they can matched witch the AHD DVR.It is obvious,the DVR and the HD camera need be the same singal technology,then work well.Need to say,MVTEAM had released the hybrid DVR that five in one mode,which means it can match the different cameras such IPC,ahd camera,CVI camera ,TVI camera and analog camera.

2.SDI-DVR
Since the standard technology level of SDI-DVR ,it is not exist the compatibility problem.

3.NVR system
When you decide to buy the ip camera from one seller ,you’d better buy the NVR at the same time.
It is advised that the IP camera and NVR should be the same brand ,if they are not the same,then the storage should support ONVIF,PSIA,GB/T 28181,RTSP and so on, what’s more ,it must be tested the compatibility firstly . That’s why we often ask the customer whether also need the NVR .So that is not our sales request but our consideration in compatibility.

4.Compress format
When comes to the Compress format,the camera and the storage device must be the same.for example,when the camera adopt h.265 .Then the storage device also should be h.265.

5.Resolution
It will be better the resolution DVR or NVR supported equal or more than the camera .for example,the camera resolution can reach 1.3MP , that means the DVR or NVR should supported equal or more than 1.3MP,or the storage image resolution will not reach to 1.3MP.
