Ltl Acorn 5310wa camera
Ltl Acorn 5310wa
Designed for monitoring wildlife or security/surveillance it is reasonably weatherproof, and can run for up to 6 months without changing batteries. The case is coloured either camouflage green or black. ===== Hardware description ===== The// Ltl Acorn 5310a// has a 5 Megapixel camera (interpolated to 12Mp ((many adverts seem to fudge whether it has a 12MP sensor))), and two passive infrared sensors. One sensor (the 'prep' sensor) is lit by two lenses angled at 50º to either side. It is basically a [[:electronic:equipment:camera:5210a|Ltl-5210a]] with more infra-red LEDs for night illumination. Described as a 12MP camera in advertising, yet it is also described as only having a 5MP sensor. The extra inserted pixels in the 4000 x 3000 images are interpolated (ie average of adjacent pixels) - ie literally a waste of space on your SD card just for marketing hype and actually a degradation of picture quality. The original version has no microphone, but later revisions incorporate a mono microphone under a small hole to the right of the PIR sensors. ^Feature^Specifications| ^Firmware version|V1.0.026TA| ^Lens|F = 2.8; FOV = 100°; Auto infrared cutout| ^Image sensor|5 Megapixel (2592 x 1944) colour CMOS| ^ISO sensitivity| | ^Image size|5 Mp (2592 x 1944), 12Mp (4000 x 3000)| ^Video size|1280 x 720 at 20fps, 640 x 480 at 30 fps, 320 x 240 at 30 fps| ^Infrared flash range|20 m| ^LCD screen|48 x 35.69 mm; 480 x 234 pixel; 16.7 M colour| ^Memory SD card|Up to 16 GB, preferably HC 10 speed| ^PIR sensitivity|Off/High/Normal/Low| ^PIR sensing distance|20 m（below 25°C)| ^Prep PIR sensing angle|Left and right light beams form an angle of 100°; Each lens covers 10°| ^Main PIR sensing angle|35°| ^Operation mode|Day/Night| ^Trigger delay|0.6 sec (when using the 2 GB SD card)| ^reTrigger interval|0 sec to 60 min| ^Still photos|1 to 3| ^Video length|1 to 60 sec| ^Photo plus video|Takes still photo then video| ^Sound plus video|no| ^Time lapse capture|1 sec to 24 hours| ^Time lapse plus photo|no| ^Time stamp photos|ID, moon phase, temperature (ºF, ºC), date and time| ^Time stamp videos|Date and time| ^Password|4-digit PIN| ^Device ID setting|4 alphanumeric characters| ^Power supply|4 x AA (8 x AA with backpack).

"//Test//" mode allows the changing of parameters, check of the sensor field of detection, and review of images stored. For normal operation it is switched to the middle position : "//On//". It flashes red twelve times to confirm operation and to give you time to leave before the camera is armed and ready to take photographs. The prep sensor wakes up the camera so that it is ready to trigger when movement is detected on the main sensor. This delay between the "prep" sensor being triggered, and the main sensor being ready is about 0.8 seconds. The idea being that the camera can stay in low power standby mode (400µA) for long periods and go to full power only when something to photograph is imminent. It can be set to take a burst of photos or a video (or both) every time the PIR sensors detect motion. In time-lapse mode it can take a burst of photos and/or a video at regular intervals, and it also takes PIR triggered images too if they occur (timing doesn't appear to be that precise, as when set for a 10 second interval, the delay between images varied from 8 to 9 seconds). You can set the PIR sensitivity to "//Off//" if you don't want the additional movement triggered images. There are also two start/stop timers so that the camera can be made to be only active during specified periods. ==== Normal operation ==== Setup mode starts up after a 2 second delay when the OFF/ON/TEST switch is switched from "//Off//" to "//Test//". The Acorn colour logo displays and the camera live preview screen comes up. Overlaid on the live image are icons and text showing camera/video/camera+, 5M/12M, battery level, SD card number of files and total capacity. If there are no key-presses for 3 minutes, the camera powers off. ==== "TEST" mode menu ==== __Blue menu background, firmware V1.0.026TA:__ ^ Setup || ^Mode|Camera/Video/Cam+Video| ^Format|| ^Photo Size|5MP/12MP| ^Video Size|720P/640x480/320x240| ^Set Clock|| ^Picture No.|01 Photo/02 Photos/03 Photos| ^Video Length|AVI 1 Sec thru AVI 60 Sec| ^Interval|0 Sec thru 60 Min| ^Sense Level|Off/Normal/High/Low| ^Time Stamp|On/Off| ^Timer1|On/Off| ^Timer2|On/Off| ^Password Set|On/Off| ^Serial NO|On/Off| ^Time Lapse|On/Off| ^Side PIR|On/Off| ^Default Set|| In this version of the firmware, if there is no SD card present the Acorn logo and sound appears, then the screen goes blank with no live screen or menu. \\ \\ \\ \\ __Green menu background, firmware V161027_53W:__ ^ Setup || ^Mode|Camera/Video/Cam+Video| ^Format|| ^Photo Size|5MP/12MP| ^Video Size|720P/640x480/320x240| ^Set Clock|| ^Picture No.|01 Photo/02 Photos/03 Photos| ^Video Length|AVI 1 Sec thru AVI 60 Sec| ^Interval|0 Sec thru 60 Min| ^Sense Level|Off/Normal/High/Low| ^Time Stamp|On/Off| ^Timer1|On/Off| ^Timer2|On/Off| ^Password Set|On/Off| ^Serial NO|On/Off| ^Time Lapse|On/Off| ^Side PIR|On/Off| ^Recycle|On/Off| ^TV mode|NTSC/PAL| ^Version|V161027_53W| ^Default Set|| In this revision of the firmware, if there is no SD card present a live screen appears with "No SD Card!" overlaid, menus are available. \\ \\ ---- ===== Examples ===== |{{:electronic:equipment:camera:dsc_0026b.jpg?300|5310wa top end}}| | | | |{{electronic:equipment:camera:dsc_0021b.jpg?300|5310wa front}}|{{electronic:equipment:camera:dsc_0022b.jpg?182|5310wa side}}|{{electronic:equipment:camera:dsc_0023b.jpg?305|5310wa back}}|{{electronic:equipment:camera:dsc_0025b.jpg?190|5310wa side}}| |{{:electronic:equipment:camera:dsc_0027a.jpg?300|5310wa bottom end}}| | | | \\ \\ |{{:electronic:equipment:camera:a.jpg?300|5310wa top end}} |{{electronic:equipment:camera:a.jpg?700|5310wa backpack separated}} |{{:electronic:equipment:camera:a.jpg?300|5310wa bottom end}} \\ \\ |{{electronic:equipment:camera:b.jpg?700|5310wa backpack separated}} {{:electronic:equipment:camera:dsc_0029a.jpg?800|5310wa bottom end open}} |{{:electronic:equipment:camera:a.jpg?600|5310wa bottom end detail}} {{:electronic:equipment:camera:dsc_0030a.jpg?800|5310wa battery compartment}} ---- ===== Tear down ===== The backplate is held on by 6 screws, and after releasing the PCB ribbon cable to the keypad, opens out to reveal the colour LCD and SD card socket: {{:electronic:equipment:camera:a.jpg?600|5310wa disassembled}} {{:electronic:equipment:camera:b.jpg?700|5310wa disassembled}} The Off/On/Test switch (seen in the bottom right corner of the above photo) is a weak point in these cameras. When the contacts corrode it becomes unreliable, and results in a variety of symptoms. Most commonly it is evidenced by the camera being unable to be switched into "//Test//" mode. {{:electronic:equipment:camera:a.jpg?400|Off/On/Test switch}} The screws, securing the backplate, screw into mounts through silicon washers to minimise moisture ingress : |{{electronic:equipment:camera:a.jpg?200|5310wa screw hole and washer}}|{{electronic:equipment:camera:a.jpg?200|5310wa screw hole}}|{{electronic:equipment:camera:a.jpg?200|5310wa silicon washer}}| The rear panel LCD is connected via a 40 pin flex cable, and mounted in a plastic carrier. |{{electronic:equipment:camera:a.jpg?400|LCD front}}|{{electronic:equipment:camera:a.jpg?400|LCD back}}| |{{electronic:equipment:camera:a.jpg?200|LCD connector}}| ====== References and Additional Resources ====== * {{ltl-acorn-ltl-5310_20manual.pdf}}
