Frequently Asked Questions


Q. What is better, a Dome or a Body camera?

A. There is no ‘better camera’ out of the two, it all depends on the environment that the camera will be installed. I.e., dome cameras can have an anti vandal housing, so if the camera will be mounted at a low level, and will be vulnerable, an anti vandal dome will be the better option. If the camera will be mounted high, and out of reach, then a Body camera may well be a better option. It will offer a bit more of a visual deterrent, and often offer a longer night vision range than a Dome would, allowing you to see further in the dark.

 

Q. Do I need night vision?

A. If you need to record in complete darkness, then yes, you will need a night vision camera. If you have some form of lighting around the clock, then it may not be essential to go for a night vision camera. Our low light cameras will not require a lot of light to give you a picture.

 

Q. Can you see the IR illumination from a night vision camera?

A. The only thing that you can see, is the dull glow from the LED’s itself, and that is only if directly in front of it. There is no beam of light emitted that can be seen by the human eye, but the Infra Red light will allow the camera to see, even when it is pitch black.

 

Q. Can a single camera cover a wide area, whilst still allowing me to identify?

A. No. You will need a wide angle camera to ‘observe’ an area, rather than identify. Having a wide angle lens, will effectively push anything that you are looking at further away from you, to allow you to fit more in the picture, so identifying will become a big issue.

To identify, you will need a narrow angle on the lens, to allow a ‘close up’ shot of your subject. One camera will not allow you to do both

 

Q. Will I be able to read a number plate with my camera?

A. You will need a specialist camera to allow you to successfully read a vehicle number plate. An ordinary camera won’t have the technology to combat the headlights when they are on. You will need the Eclipse technology to black out the headlights, and allow you to read the number plate without any glare or white out issues.

 

Q. Can my number plate camera also be used to cover a wider area?

A. No. You will need to have the width of the vehicle taking up a majority of the screen – ideally the whole width. This means that the only way of being able to guarantee a positive reading on a registration plate is to have a narrow angle, and the sole purpose of this should be to read number plates. You will need to go for an additional camera if you need to observe a wider area.

 

Q. What is Real Time recording?

A. Real time recording is when you record at the same speed as real life. If you record in real time, you will not notice any time lapse, or broken movement. To have real time recording, you will need to have 25 frames per second (FPS) on each camera.

 

Q. Do I need to record at Real Time?

A. For most applications, you won’t have to go for real time recording. With Domestic applications or similar, going down to half of real time, or even lower is ample, providing the resolution is high enough.

For high risk applications, it’s essential. Anywhere where ‘sleight of hand’ could be an issue, i.e. in a casino or a bank, it is always better to go for a real time recorder to avoid missing any quick movements that might otherwise go unnoticed.

 

Q. What is motion detection?

A. You can have your system only record when there is something to record to save on the hard drive space, and also make much easier to search for an event.

Recording on motion detection means that you will only record when there is something of relevance to record. The system will just be viewing until there is movement detected by the camera. Once movement is detected, your DVR will start recording. Once the movement has passed, you will have an Event in your list of recordings. This saves having to fast forward through a whole day of footage for an incident that may have lasted for just a few seconds.

 

Q. Can I mount a dome camera directly onto a wall?

A. Yes, you can. It all depends on where the camera is looking. I.e. you cannot have a dome camera on a wall, and try to look at a door on the same wall unless you have a bracket for it. Most of our dome cameras have a bracket that can be used in this case.

If you are looking away from the wall, then you can mount directly on the wall. We also do a vandal resistant base where you can house all of the terminations, which sits behind the camera. This will give you added security.

 

Q. What is better, an Optical zoom, or a Digital zoom?

A. Optical zoom is a true zoom, which will not distort or pixelate, much like a compact, or SLR camera operates. A digital zoom will magnify an image in the same way a mobile phone zoom will. This is fine if you don’t need to zoom in far, but you will notice that the image will become less sharp the more you zoom.
