Precautions All User Manuals and leaflets should be read thoroughly before proceeding with operation of the equipment It is also advisable that all User Manuals and Instruction Leaflets supplied are kept readily available, for reference when the equipment is in general use The following precautions must be adhered to at all times and must be considered in addition to any advised precautions issued at the relevant worksite or work area • Do not supply power to IR136 Thermal Camera beyond the followed requ
The IR136 Thermal Camera does not incorporate any user serviceable parts. Never attempt to disassemble or modify the camera. Opening the unit invalidates the warranty • Do not loose the bolts on the bottom of the camera, to avoid any effect on the detection and image. • Do not use thinner to clean the camera parts, especially the optical part. • Please power off the camera if you will not use the camera for a while.
Introduction IR136 Thermal Camera is a long range camera used for anti-aircraft and surveillance application. Based on general IR technology, and integrated Guide unique research, IR136 is a thermal Camera is with several optimized solutions.

Features Fig 3-1 IR136 Features No.
Nonlinear correction clears up “Ghost”, which is important for Nonlinear 5 correction, no getting high-quality image.
Annotation 1. NUC (non-uniformity correction) Because of special technic, a thermal camera without NUC will get the 4-1a image when shooting at a target with uniform temperature. The spots in the image are called “bad pixels”, and the shade (with uneven brightness) is generally called “ghost”. Both of them will affect detection especially when detecting a long range target. After NUC, when shooting at a target with temperature, the camera will get the 4-1b image.
correction, you can change the relative value. We will call the value “bad pixels threshold”. 3. Calibration Calibration is an operation to obtain the original data for NUC. For camera, calibration is actually an algorithm after taking a uniform target image. In work site, the uniform target can be clear sky, the built-in shutter, or the closed lens cover; for you, calibration is pressing some buttons in the keyboard! 4. Background When you calibrate, a uniform image you get is called background.
Controlling keyboard This controlling keyboard realizes all the functions by RS 422. Its smart design, easy operation supply you a stable control of the IR136 Thermal Camera. Fig 5-1 controlling keyboard The above 4×3 keyboard has red and green parts. SHIFT is used for switching between red and green. When red part is bright, it indicates you can use the red part functions, when green part is bright, it indicates you can use the green part functions.

Procedures This chapter describes procedures of using the IR136 Thermal Camera. For more detailed instructions, please refer to followed contents after this chapter. 1、 Fix IR136 camera body firmly according to field conditions. It is necessary operation when using IR136 camera for the first time or changing its working place. 2、 Connect power, RS422 / RS232 control cable, video output cable and etc. Four groups of cables offered along with the camera. The interface is multi-core.
Basic functions Note: When turning off the camera, all the current parameters will be recorded down, including: brightness, contrast, camera mode, zoom, polarity, reticle and etc. When turning on next time, these parameters will be used. 1. Brightness adjustment IR136 Thermal Camera also has auto brightness and auto contrast function. Press “A” to switch between manual, auto brightness and auto contrast modes.
Fig. 7-1 Brightness Contrast Camera Mode Polarity Zoom Fig 7-1 3. FOV switchover and electronic zoom in Image zoom can be switched between 1x, 2x, 4x and 8x by changing its FOV and carrying out electronic zoom. FOV switchover and electronic zoom both are used for deflating or magnifying the image. Nevertheless, 1x and 4x are realized by changing multiplying factor through built-in two sets of IR optical lenses. 2x and 8x are done by electronic zoom. Fig.
Z=4，NFOV Z=8（NFOV & 2× electronic zoom） Fig 7-2 4. Focus Adjustment In order to get clear image, manual focus adjustment is necessary after starting up. Generally, NFOV is sensitive to focus adjustment. So, switch camera to NFOV firstly. After getting correct focus, then switch it to WFOV. The image quality should be the same for the same target.
p=0 white heat p=1 black heat Fig 7-3 6、Reticle IR136 offers four types of reticles (refer to fig 7-4). Press “ST” to switch among 6 modes: four types of reticles, canceling reticle and displaying debug information bar, canceling both reticle and information bar.
4 types of reticles Original background data Corrected value Running Time FPA Temperature Fig 7-4 19
Advanced functions 1．Image enhancement （air & ground detection） In normal mode, when detecting different targets with big temperature difference simultaneously, such as relatively high temperature ground and low temperature air, the high temperature part will be too bright and the low temperature part will be too dark. The image enhancement mode (air & ground detection mode) can give attention to both high and low temperature parts.
Quick Trouble Shooting This chapter includes: z How to clear up “Ghost”? z How to correct bad pixels? z How to save data and restore misoperation in the field? 1. Clear up “Ghost” Self-check and cooling process will last for about 5~8 minutes after powering on the camera. When it finishes, after 30 seconds, the camera will switch between two FOVs and perform auto 1-point calibration separately. The lens cover will open automatically after auto calibration.
cross should be a bright spot (please note, not all bright spots are bad pixels). You can change the Bad Pixel Threshold by “B+” and “B-“, and also you can use the default value. Then system will search a bright spot with the set Bad Pixel Threshold, you should judge if it is a bad pixel by moving the camera. If it is a bad pixel, press “E+” to correct it; If not, you can pass it by pressing “E-“. Press “SB1” to save bad pixel correction result.
