8v Bullet Camera


8v Bullet Camera








The original bullet camera. This model of camera is quite a few years old but has the advantage that it doesn't need the regular 12v power supply. Instead it can be powered from a smaller and lighter 9V battery (PP3). It will however also work from a 12v supply.


The camera specification is lower than our later models but still features a 320tvl CMOS image sensor and Sharp lens. This camera is suitable for most uses, especially indoors but in many cases will not match the quality of some videos now shown on the website. Camera is supplied with 9v battery clip and instructions. Dimensions 70 x 23 mm.
