    If you're new to the realms of the DogCam and other helmet camera technology then you probably have plenty of questions. If you can't find the answers below then please contact us and we'll be happy to help.


    Q: What is the best bullet camera?
    A: Have a look here for more info on the best bullet camera?

    Q: I need a helmet camera set up. What can you offer.
    A: We have been working hard to make sure our customers have the latest information on helmet camera technology. There are lots of new products on the market related to this and we will do our best to ensure you make the right choice. The basics come down to economics, the more you spend, the better the system you will have and usually the better the image quality will be.

    Q: Will this work with my camcorder?
    A: If your camcorder has a/v inputs then yes it will. You can check to see if your camcorder is listed here in "camcorders with a/v inputs". If your camcorder is not on the list then all is not lost, the best way to check is to either contact you manufacturer or you can check it's manual for a section describing how to record from an external source. It might be titled "recording from a TV" or "dubbing from a VCR"

    Q: I don't have a compatible camcorder and i don't really want to carry a camcorder around with me. Do you have a more compact recording solution?
    A: Yes we do! We now retail the archos 404 hard disk video recorder for users looking for a smaller solution. The recording quality of 640x480 (2500kbs) is pretty good and works perfectly well for presenting media for the web or playback on smaller devices. Or you might like to look at our PVR500r digital hard disk recorder which can record at a higher resolution and higher bitrate for better video quality. If you are looking for a high quality solid state recorder then check out the ME1 digital video recorder.

    Q: I don't know what i'm doing, can you help?
    A: Yes! That's what we do best. We can help you put together a kit that suits your needs and then give you guidance on how to use it effectively.

    Q: I'm interested in setting up a complete DVD burning solution so I can hire out helmet cameras to my customers and then sell them the DVD.
    A: Contact us. We can put together a bespoke system for you.

    Q: Does it come with leads to connect to my camcorder?
    A: In most cases you will use the a/v cable supplied with your camcorder to plug directly in to the DogCam. The a/v cable is the one used for playing back from your camcorder to a TV or VCR. When the camcorder is put into "VCR" or "Play" mode, the output becomes an input. There is a guide here: Guide to connecting to a camcorder.

    Q: My camcorder has DV in, will this work?
    A: No, DV in is a digital connection for computers and other digital equipment, it is possible to convert the signal but pointless because of the cost and effort of carrying the extra equipment involved.


    Q: What is the difference between 420, 480, 520 TV lines?
    A: Simply, the cost of the camera is relative to the quality of the image it produces. The resolution is measured in TV Lines. Older Cmos cameras used to have a max. resolution of about 380 TV lines which is considered to be low resolution and comparable to an old VHS camcorder. 420 lines is medium resolution and with good CCD electronics produces a respectable picture. 480 Lines and above is considered to be high resolution in the bullet camera world. The picture is much sharper, colours more vibrant and more comparable to a digital camcorder. The majority of camcorders on the market today at an affordable price can record 550 lines of resolution.
    Remember, No matter how many lines of resolution a camera has, if it's not backed up by quality electronics and lens it'll still be rubbish. Bullet cameras used as helmet cameras are usually subject to much harsher filming conditions. A high quality bullet camera can adjust to these changing light conditions much quicker than a cheap CCTV security camera can.

    Q: My Sport is xxx what camera do you recommend?
    A: All of our DogCam range is suitable for most sports, it's more to do with the quality of the finished product when it comes to choosing a camera.

    Q: Is your camera waterproof?
    A: All DogCams are water-proof to the extent that if they get wet, the water won't get in. This is not the same as submerging the camera which is really not recommended. NOTE, you will be able to use the DogCams in the rain but a couple of water droplets on the lens will distort the view to the camera. This is the same for any camera and usually makes for a dull video. The Pro520 and the Pro550 zoom are ip67 rated so they can be dunked underwater without problems. For underwater filming we recommend the Viosport H2o camera which is rated for depths of over 150ft.

    Q: Will the suction mount hold at high speed?
    A: Yes, The suction mount completely rocks. After years of testing various mounts, this is the strongest most versatile way to mount a camera to a fast moving object.

    Q: What is PAL and NTSC, I Have seen cameras on eBay that say they do both?
    A: PAL is a UK video standard and NTSC is an American standard. A camera can only be PAL or NTSC but not both at the same time. It has to be manufactured as one or the other. The person you have seen that says they do both is relying on the hope that your TV or VCR will decode an NTSC signal (most new ones do). However, the same is not true for camcorders. If you have a PAL camcorder then it will only accept a PAL signal from a PAL bullet cam. An NTSC bullet cam will give a black and white/fuzzy image that breaks up. Same thing in reverse, if you have an NTSC camcorder, you would need an NTSC bullet camera. All our cameras are PAL for the UK market unless requested.

    Q: What is Exview, what does it do?
    Exview is an amazing technology invented by Sony Corporation. As the demand for smaller cameras grows, the lens aperture is decreased allowing a lot less light to travel to the image sensor in the camera (aka the CCD). Exview which was originally intended for camcorders is a method of fabricating micro lenses on the chip, one lens for every pixel. These micro lenses focus the available light on to an optimised CCD matrix resulting in a much higher light sensitivity. Sony Exview fitted cameras then have the ability to work at much lower light levels and provide a fantastic image in less than perfect filming conditions.

    Q: What is SuperHAD and why do I need it?
    A:
    SuperHAD is a proprietary technology developed by Sony Corporation. The HAD sensor (Hole-Acumulation Diode) has been designed to give a greatly improved sensitivity resonse by the incorporation of the new semiconductor technology developed by Sony. CCD cameras use micro-lenses for every active pixel known as on-chip lenses. The optimsed shaping of these thousands of micro-lenses ensure that the invalid area between them is greatly reduced and therefore increasing image sharpness and light sensitivity. The microlenses on a standard CCD chip cover about 60% of the effective photon sensors available. In a SuperHAD configuration the lenses cover around 90%.
