Teardown: Swann Night Hawk Wireless Security Camera | ABieneman's Blog - The second board is the photo sensor and 8v to 5v conversion board. It's miles marked with v801cv28. Great additives include image sensor – no markings on top but based from swann’s specifications is a 1/three″ shade cmos, 510 x 492, 380 lines sensor in a forty eight-clcc bundle rated for five volts. Sensor is protected through the focusing cover which lets in adjusting sensor to lens distance via rotation of the lens holder. At the returned of the board there’s a 14.318 mhz (ntsc sampling frequency) crystal. Voltage conversion is done via 75l05 5v voltage regulator and a ten uf, 5v capacitor. In the whole digital camera best leds are the usage of supplied 8v from the power deliver, relaxation of the components use 5v supply:. The first board which you see while you unscrew the front of the camera is the led board. There’s an o-ring (not visible on the picture) between the front and the returned of the digital camera which presents safety in opposition to factors and it greater or less does it task – internal of the digital camera case appearance easy and water loose. Main elements on the led board are the 12 infrared leds connected in collection of 3; light sensitive resistor which turns leds on in low mild conditions; and 2 role dip transfer marked “on khs22” which selects the transmission channel (1 via four) . The back side has a 3 pin device marked y2, a five pin chip marked 3272 – probably an op-am, and a variable resistor to adjust sensitivity. Board is marked with aee, v812ic10:. The 0.33 board is the rf board and is marked vt24a0x4 040315. This board is hooked up to video sensor board via yellow records twine, pink (torn out at the photograph) and black electricity deliver wires. It is also connected to the channel choice switch on the led board through white and yellow twine and to the microphone board through the white information twine. Board contains following chips: “bj8p153snj ar03-a 0812” that's a 2.4ghz transmitter (channel selection switches are soldered immediately onto 2 pins at the chip); 17.734475 mhz crystal which i could handiest pick out as buddy related frequency. At the lower back there’s “e07sl e1c744 m52” which i discovered is defined as “unmarried serial input pll frequency synthesizer on-chip 2.Five ghz prescaler”. My rf know-how could be very restrained so i did now not pursue this board any in addition:. I've recently acquired several broken swann night time hawk sw231-woc wi-fi security cameras and figured i would record the tear down procedure and something exciting i would discover. My goal on this project turned into to satisfy my interest, try my palms at solving them and perhaps even examine some thing inside the procedure.
