3) Video display brightness / contrast / color saturation adjustable; LCD backlight brightness adjustable .
4) Video Format NTSC, PAL automatically recognize and standard prompt.
5) Video signal level measurements, to test if video signal level is attenuated.
6) DC12V 1A power output, to provide temporary power to the camera.
7) Audio test, test microphones and other audio devices.
8)Multi-standard color bar signal generator (seven standard selectable), outputs standard color bar signal that meets the world.
9) Dome camera address search function to help users find the dome camera address.
10) Cable test function, testing network cable ,telephone line. Testing wire sequence and conductivity.
11) Support RS232/RS485/RS422 interface, baud rate 150 - 19200bps adjustable.
12) support PELCO-P, PELCO-D, SAMSUNG,AD Manchester..., totally more than 30 control protocols.
13) The PTZ data monitor helps user analysis control protocol command data. It helps engineers to determine whether the RS485 transmission is normal.
14) PTZ control, user can control the camera pan,tilt,zoom, focus, iris. User can also operates dome camera built-in menu, save and recall preset position.
15) Graphic display of the battery level in real time. With advanced power control and protection circuit, low-power design, the device can work 11 hours for a single charge. The battery charge time is about 4 hours.
1) video test
This tester device has a built-in 3.5-inch high-resolution digital LCD monitor, user can more easily inspect camera image quality.The device can automatically recognize the input signal standard(PAL or NTSC) .
2) Digital zoom function
With built-in high-speed image processor, the device can display portion content of input video. With digital zoom, user can inspect video details more clearly. For example, the camera image corners can be enlarged for detailed observation, finding focus blur.
3)Video signal level measurement
The device can measure video signal level, and tell whether the video signal strength attenuated or too high. If the video cable is too long or in poor condition, the video signal will be attenuated. Attenuation of the video signal will cause the image dim, lower image dynamic range. If the video signal level is too high ,it will cause the virtual shadow, and reduce the sharpness of the image. The video signal level measurement can display the video signal level value in real-time. if the value is out of normal range, a message will appear on the screen to remind.
4) PTZ control function
Built-in Pelco-D / P, SAMSUNG, Panasonic AD Manchester ... Totally more than 30 PTZ control protocol. Though RS485 ,RS422 or RS232 interface, the user can control the PTZ pan ,tilt , zoom , focus, and iris. Support pan speed, tilt speed adjustment; save presets and recall preset ; operate dome camera built-in menu, setting parameters of the camera.
5) multi-standard video signal generator
Multi-standard video generator send a variety of standards(PAL, NTSC and subbranches ) standard color bar signal though Video Out port. Can be used to check the video transmission path of video channel. By inspecting received standard color graphics in the surveillance center, user can judge signal attenuation or interference during transmission.
The device can also displays input video while Video Out outputs color bar signal. This is used to test video transmission.for example testing a video optical transceiver or a video cable.
6) DC12V 1A power output function
The device has a built in 12V 1A power output, to provide a temporary power supply for camera when power line is not ready or camera power adapter is worn out.
7) Audio test function
Audio teste function can test microphones and other audio equipment.
8)Cable test function
This tester device has a cable test function. user can test various cable connection (2 or more wires connected). The device can also display the number of cable (remote test gadget number. Eg. 255). Equivalent to the cable splitter, user can tag numbers for the cable heap using multiple remote test gadget.
9) PTZ control data monitor
This device can capture data from RS485/RS422/RS232 interface. Displays codes sent from multifunction keyboard or DVR. Used to inspect the surveillance center PTZ control command data, to verify RS485/RS232 data transmission. Device screen displays hexadecimal code, for example: PELCO-P: A0 00 (address) xx xx xx xx AF xx PELCO-D: FF 01 (address) xx xx xx xx xx
10) PTZ address search function
Video security tester has address search function. It can help user to find dome camera address quickly . When user need to maintain a dome camera, he may not know the address of camera. There will be a lot of effort to remove the camera to look for the address. With PTZ address search function, user can quickly find the address of the dome camera.
