Q & A’s

You may have many questions when it comes to CCTV. So, I have answered some of the most popular enquires below. Don’t worry if your question is not here, just complete the form below, and I will get back to you. If you’re asking it, the chances are somebody else is.

This section is based on customers feedback

Questions have been categorised for easier reference 🙂

Q: Can I see the images on my phone?

A: All our D/NVR’s, (recorders) will, when connected to your internet transmit live and playback images to your smart phone or tablet.

Q: What type of mobile device, (phone or Tablet) must I have?

A: Any modern smart phone or tablet should be compatible, but you can check this by searching for the apps on your device’s app store, if you can install it, it will work.

  • Viper D/NVR (recorder) search for SuperLive Plus
  • Kestrel D/NVR (recorder) search for Kestrel Viewer

Q: Can I get notifications on my phone if somebody comes onto my property, (in my garden)?

A: Tricky one this, the short answer is yes as the recorders use certain algorithms in their firmware to send you notifications, (Push or emails). However, these are very black or white, so the best solution would be to add a PIR sensor, which monitors for movement and heat given you a more accurate alarm.

Other ways of getting notifications could be achieved by the built-in analytics such as ‘Tripwire’, ‘Intrusion’ etc. these are explained in further detail on our support page.

The internet is not as good as the providers would want us to believe, especially in established/remote areas. Imagine new technology being piped through old cabling/exchanges, it stands to reason things will break down, or speeds will be affected. The internet can be affected in many ways, workmen may have cut a cable down the road, weather conditions such as wind on overhead cables, and lighting etc may also affect the performance of the service provided by your internet supplier.

Q: My Router is not close to where I want the recorder, is it WiFi

A: Most of our D/NVRs (recorders) require a cable to be connected to the router. However, if your router is not near the recorder we could use a powerline adaptor, (aka Homeplug).

Q: My internet is slow, will this affect my CCTV?

A: A common problem I hear all the time, but we have to ask ourselves is it the internet or the WiFi from your router which is slow?

  • 99% of our D/NVR’s (recorders) are connect to your router by a LAN cable, so the WiFi side can be taken out of the equation.

Q: I have superfast broadband, why is it slow to view?

A: The two most important factors for remote viewing is:

Download speed

When you view images through your device, (PC, Phone or Tablet), you have actually downloaded that information. In fact, nearly everything you view, read and experience on the internet is downloaded to your device at least in part, and that is why download speeds are so important.

A high download speed gives you the ability to download online content faster than through a slow connection. This means you can see more and do more online, as you will not have to spend as long waiting around for pages to load and downloads to finish.

Every broadband provider will give you a maximum download speed, measured in megabits per second, at which your connection could potentially operate.

Upload speed

If downloads refer to the information received through your device, then uploads refer to the information you send through your device. Posting a photograph on Facebook counts as an upload, as does sending images from your DVR.

Higher upload speeds make these processes run a lot faster (we have all been through the boredom of waiting for our holiday snaps to upload onto Facebook), but, as with download speeds, higher upload speeds are generally more expensive.

When it comes to CCTV, your download speed on your viewing device can only be as good as your DVR routers upload speed, as images are not stored online.

In short for you to view your images, you will need to upload them, before you can download them… ..

A good way of seeing how the internet is performing through your D/NVR is to have a look at the lights on the back where the LAN (Internet) cable plugs in. See image below, marked within a red square.

There will be 2 lights either side of the LAN socket, the left LED is the internet speed indicator, and the right LED is the activity indicator.

Q: How long will the HDD, (Hard Disk Drive) record for?

A: This will depend on several factors such as:

  • What codex/compression are your using, (H264 or H265)?
  • How many cameras you have?
  • Are you recording 24/7, Motion Detection or Alarm only?
  • What resolution & framerate are you recording?
  • What video quality?

To help with this have a play with our online storage calculator, (click here)


Q: What happens when the hard drive is full?

A: Normal practice is that the HDD, (Hard disk drive) will erase the earliest day/hour to make space.


Q: Can I just delete a piece of footage?

A: No, you would need to format the entire hard drive, (erase everything)


Q: Can I use any HDD?

A: I suppose you can as they will work, but both Seagate and Western Digital make specific HDD’s for the CCTV market, (check out their promotion videos below)

  • Seagate ‘Skyhawk’
  • Western Digital ‘Purple’

Q: What’s the difference between 2, 5 & 8 MP?

A: Camera resolution is defined as the amount of detail that a CCTV camera can capture. Resolution is measured in pixels. A higher number of pixels means more detail and larger images without blur or being grainy. Resolutions are measured in Megapixels, which is just over one million pixels, 1,048,576 to be precise.

I have a page explaining a bit more, click here.

Some of our camera specification are, (see individually cameras for full specifications)

  • 2MP, 1080p /1984 x 1105 = 2,192,320 pixels. AKA HD
  • 5MP, 2592 x 1944 = 5,038,848 pixels. AKA HD Plus
  • 8MP, 3840 x 2160 = 8,294,400 pixels. AKA 4K

Q: is 8Mp better than 5Mp, or 5Mp better than 2Mp?

A: In general, yes, but pixels is just one part of making the image, the Lens would need to be considered, (see FOV/Field of View). Also, the recorders frame rate & compression (cameras in IP) would need to be taken into account as well.

Q: Can it detect movement?

A: the recorders has built in motion detection which can be programmed in several ways including on/off, area, sensitivity etc. Also built into the firmware is intelligent video analytics which may include:

  • Face Detection
  • Crowd Density
  • People Intrusion
  • People Counting
  • Object detection
  • Tripwire
  • Intrusion

See individually recorders details for full specification

Q: Will my cameras see at night?

A: Most modern cameras now have built in Infrared leds, (IR’s), and which will automatically switch the camera to monochrome when the night draws in. The IR’s will project a beam depending on the amount of leds the camera has, typical examples would be:

  • 24 leds  = 10-15 meters
  • 36 leds = 15-25 meters
  • 48 leds = 25-40 meters

Q: Will I get spiders over my cameras?

A: Unfortunately, spiders do see the IR’s lights and will set their traps, (cobwebs), which in turn reflects light back into the lens, (like rain).

There are a few things you could try:

  • Treat the camera with a spider repellent such as ‘Spiderex’ Buy here
  • Turn off the IR’s on the camera and add a standalone IR lamp away from the camera.

ColorVe cameras by HikVision are not effected by cobwebs as they have a built-in white light which enable the camera to produce full colour images 24/7 click here for more details.

Check out or guide to spiders

Q: What angel of view will the cameras produce?

A: This will vary on the Lens the camera has, most cameras have a 3.6mm fixed lens which give a viewing angel of 78 degrees +/- 2%. Some have a varifocal lens, (2.8 – 12mm) which are manually set when installed, these can get 92 degrees +/-2% when set at 2.8mm. Varifocal cameras are extremely popular on domestic homes.

See products for individually specification

What does frame rate mean?
Frame rate refers to the number of individual frames that make up one second of recorded video. So, how many frames per second (FPS) do you need for your CCTV camera to capture the best footage possible?

Why does frame rate matter?
The greater the FPS, the smoother the video recording will be. For example, if your frame rate was 1 FPS and you were trying to capture footage of an individual running, you will only be able to capture one frame containing the individual as he/she would have cleared the field of vision (FOV) between frames.
