Range of Grandstream GXV3601 surveillance cameras




Grandstream has a large set of IP surveillance cameras in its portfolio. According to the form factor alone, there are three line of cameras “boxing”, “cube” and “dome”.



It is easy for everyone to decide which form to choose a camera for, it’s more difficult to further figure out the identical cameras, which differ only in the list of different parameters. In this article I want to help understand the differences between the cameras of the “boxing” line, and at the same time describe their common functions.


Short review



The range of cameras GXV3601 consists of cameras GXV3601_P, GXV3601_LL and GXV3601_HD, here you can add a more expensive camera GXV3651_FHD. The entire line looks approximately the same: a metal body, a lens jack, a standard tripod mount.



The GXV3601_P and GXV3651_FHD cameras also include a connector for automatic iris control.



On the back side, the connectors: Ethernet (PoE support), adapter power, for an SD / MMC memory card, input and output for analog audio, analog video output (except GXV3601_HD), USB, reset button and operation LED:



The green connector is used to connect sensors and control relays. Thanks to it, you can set the camera to automatically turn on to record when an event is triggered, and you can also remotely control, for example, a door lock. Note that neither the camera position nor the lens can be remotely controlled, but you can control a third-party PTZ (a separate device that controls the position of the camera), it is also connected to the green connectors.

The package includes a lens, power supply and brief instructions for connecting:
Brackets for mounting are not included in the package, since there are a large number of them. They can be bought at any Epicenter type supermarket and they are attached to the camera with standard connectors:



Also, the cameras can be placed in standard protective housings for outdoor installation. There are heated covers, vandal proof, etc.

Now about the differences. GXV3601_P, GXV3601_LL and GXV3601_HD - all of them are in the same price range, the Full HD GXV3651_FHD camera, which is more expensive and has a number of additional qualities, is a little apart. The choice between them should be done depending on the lighting conditions, where they will work and the quality of the video resolution.
For convenience, I took the trouble to compile a comparative table of only those basic parameters that help to do this:



It can be seen from the table that at the lowest light it is better to use the GXV3601_LL camera (Low Light) because of its highest sensitivity. (The sensitivity parameter Volt / Lux * sec indicates the voltage that appears on the matrix when it is irradiated with light of 1 lux for 1 s, that is, the higher the value, the higher the sensitivity).

If it is assumed that the illumination will vary within wide limits, the GXV3601_P camera is better. The CCD matrix produces less noise than CMOS. In combination with automatic aperture change, it also allows you to cope well with poor lighting and does not allow illuminated images in high light.
GXV3601_HD produces a high-resolution picture, but requires constantly good illumination of the room.
If you need high resolution in good light and work in the dark, you have to fork out for the GXV3651_FHD.



There is a light sensor that disables the infra-red filter in the dark, there is a function of switching to black-and-white mode automatically and according to a schedule.



The above shows how the image changes when darkened. When you set the infrared filter to turn off automatically, the white balance shifts, but the noise level drops noticeably. When you enable the appropriate setting, you can automatically switch to black and white when dimming.

If the camera still can not cope with a wide range of illumination, you can choose a lens with automatic iris control.

Note that not one camera has infra-red illumination and can not work in complete darkness.

Features and additional features of IP cameras



Motion Detection and Alarm


Grandstream IP cameras can be flexibly configured for motion detection. In the picture you can mark the zones and in each zone determine the sensitivity.



Schedules can be assigned to each part of the screen to prevent operation during working hours. Both in response to movement and in response to the operation of other sensors (smoke sensor, infra-red detector, etc.), you can assign a number of tasks:
- record video and sound in SD or USB
- upload to an FTP server
- send JPEG by e-mail
- triggering of outgoing contacts
- signaling to the central monitoring system (GSurf), where, in turn, you can configure automatic output of the image on top of the screen, recording to a PC disk, audio notification.

Registration on the SIP server

The IP camera can be connected to the IP PBX as an IP phone. This opens up a number of additional possibilities. For example, you can easily call her from a video phone and see a picture, make a voice announcement on an audio system connected to the camera, hear audio from a built-in or mounted microphone, open the door of the lock. From the camera, you can also receive a call to the phone in the event of an alarm or motion detection.

WiFi work

GXV3601_xx and GXV3651 can work wirelessly if you connect such a WIFI adapter to USB:



Email Alerts

It is possible to configure the SMTP server to send emails when an alarm is triggered or when movement in the camera is detected.



PTZ

Grandstream IP cameras themselves DO NOT support remote control, but it is possible to control the position of the camera if you connect a PTZ device from another manufacturer. The Pelco-P and Pelco-D protocols are supported:

Free Surveillance System GSurf

This monitoring and recording system can integrate up to 36 surveillance cameras. The program supports remote viewing, management and registration from anywhere on the Internet or corporate network of several or all IP cameras at once. To install the program you need a computer with Windows. The software is freely available:
http://www.grandstream.com/support/tools
To make it easier to navigate in an environment, it is possible to place cameras on a map. The icons of the cameras for which the alarm went off will change color, there is the possibility of instantly automatically displaying the image on top of all windows. The image can also be viewed by double-clicking on the camera icon. The list of triggered alarms can also be viewed without problems at the bottom of the screen:



For example, in order to configure the recording of video on a disk in GSurf immediately, as the camera detects movement, you need to perform two steps:
1. Create a rule Configuration - Event Configuration, where we specify the signal playback, recording and displaying pictures on top of windows.



2. Configure the Configuration - Device Configuration camera to comply with this rule.
In addition, it is necessary to configure the motion detection in the settings of the camera itself and indicate the alarm sending in GSurf (tick 'Upload to Alarm Center'):

ONVIF Support

This means that in addition to working with GSurf, the cameras are compatible with security systems from other manufacturers that support the ONVIF standard.
