Q13: What is the difference between Analogue and IP?
A: In the analogue CCTV, cameras capture an analogue video signal and transfer that signal over
coaxial cable to the Digital Video Recorder (DVR). Each camera powered by plugging in the
power supply right at the camera. The DVR converts the analogue signal to digital, compresses it,
and then stores it on a hard drive for later retrieval. Intelligence is built into the DVR to handle
such things as scheduling, motion detection, and digital zoom. Monitors (for viewing the video) are
connected to the DVR, or it can be set up to publish over an internal network for viewing on PCs.
The DVR can also be set up to broadcast over the Internet and can have password protection and
other features.
In the IP CCTV, each network camera captures an analogue image but immediately converts it to
digital inside the camera. Some digital processing can happen right at the camera, such as
compression and motion detection. The digital video stream is then broadcasted over the local
area network (LAN) using Ethernet (CAT5 or CAT6) cable. Power is supplied to the cameras
through the Ethernet cable via Power-Over-Ethernet (POE). The Ethernet cable for each camera
is plugged into the switch which feeds into the network hub. As with all network devices, some setup needs to be done for each network camera to set up its IP address and other identifying
A Network Video Recorder (NVR) performs the same function as its DVR cousin in the analogue
world. It captures each camera's signal, compresses, and records it. The main difference is that
the video feeds are digital (and much higher resolution) and not analogue. Software built into the
NVR provides features such as intelligent search and zoom, etc. The NVR combines the video
stream from the cameras and handles the broadcast over the LAN and internet for local and
remote viewing.
Q14. Which approach is more cost-effective Analogue or IP?
A. For now, installing analogue cameras coupled with DVRs still the most cost-effective approach for
most security applications. However, the cost of IP cameras and components is rapidly declining,
making the IP systems more and more affordable and desirable.
Q15. Which system has better quality Analogue or IP?
A. There are poor and good quality products no matter which type of system is used. With that being
said, network cameras offer some technological advances in the areas of video quality and
wireless installations. Analogue cameras cannot provide resolution above TV standards.
Resolution of IP cameras can be many times higher and they can capture a clearer image when
objects are moving. This could make a difference in high risk applications such as for casinos and
law enforcement.
Q16. Which system is easier to install and configure Analogue or IP?
A. If an IP network is already in place at the installation site, and it can handle the additional load of
the new cameras, then IP cameras will be easier to install. If additional RJ-45 jacks are needed to plug
in the network cameras, then the installer only has to run a CAT-5 cable from the camera to the
nearest switch. An inexpensive switch can be installed right at the nearest wall jack. In contrast, each
cable for analogue cameras must be run all the way back to the DVR. If upgrades are needed to
existing IP network to handle the additional load, obviously the installation would be more difficult.
The power to cameras can be handled easily with either technology. For IP networks, built in POE
adaptors make sending the power through the existing Ethernet cable easy. For analogue systems,
use RG59 Siamese cable combines video and power cables into one jacket. Either way, there is no
additional cabling for power. POE can run 328 feet without a repeater, and RG59 can be run 1000
feet without a repeater.
Q17. What is a Security DVR?
A. DVR stands for Digital Video Recorder. A Security DVR is capable of taking the video from digital
or analogue cameras and recording it into a digital format on a hard drive. It can record high quality
maintenance free video for weeks or even months.
Q18. What is a video capture card?
A. A video capture card or DVR card is a graphic card inside the Security DVR system which
captures the signal from the cameras and stores the video on the hard drive.
Q19. How many hours of video the Security DVR can store?
A. It depends on number of cameras, frames per second (FPS) and amount of available hard disk
space. Our preconfigured systems usually provide several weeks of archive on motion detect
Q20. How does motion detection work? Through the camera or software?
A. Motion detection works through the software in the DVR system by recording video when pixels in
the image change. Most Security DVRs offer a sensitivity scale so the user can set the sensitivity
of the motion detection.
Q21. Can I view live and recorded video locally?
A. Yes.
Q22. Can I view live and recorded video remotely?
A. Yes, most of our Security DVR systems are Internet enabled. You can view live and recorded
video from anywhere through the Internet.
Q23. What kind of broadband do I need? How much bandwidth?
A. Basic DSL or cable will suffice in most cases.
Q24. Can several users view one site at once?
A. Most Internet-enabled Security DVR systems allow multiple users to view the same site
simultaneously, however; the bandwidth will be shared between them.
Q25. Can I record audio?
A. Yes, if the Security DVR system comes with an audio option you can record audio. Most analogue
cameras do not come with built in audio, so you will probably need a separate audio kit.
Q26. How many cameras do I need to cover 8000 Sq. Ft parking lot?
A. Ideally each camera covers a maximum of 1000 Sq. Ft, therefore; 8 cameras should be suitable for
such a case.
Q27. Can I use my existing cameras?
A. Yes, you can use your existing CCTV cameras. Simply plug them into the rear panel of the
Security DVR.
Q28. What are the common camera formats?
A. Common formats are 1/4”, 1/2”, 1/3”, 2/3”, and 1”. The size of the sensor directly affects the field
of view obtained. When using the same size lens on different format sensors, different viewing
areas are obtained. For example, using a 6mm lens on a 1/3” sensor will give you a 37º field of
view. Using the same lens on a 1/2” sensor will increase the field of view to 56º and 74º on a 2/3”
Q29. What camera lens size is the best for my application?
A. Mezory CCTV carries a large selection of security camera lenses, but the lens you will need
depends on where you plan to use it. Send a Technical request to our Support team to determine
the type of lens that suit your needs.
Q30. What is the meaning of C-Mount Lenses?
A. An industry standard for lens mounting. The C-Mount has a thread with a 1 inch diameter and 32
threads per inch. The distance from the lens mounting surface to the sensor surface is 0.69 inches
(17.526 mm). It is possible to mount a C mount lens onto a CS mount camera with the use of a
CS adapter ring.
Q31. What is the meaning of CS-Mount Lenses?
A. An industry standard for lens mounting. The CS-Mount has a thread with a 1 inch diameter and 32
threads per inch. The distance from the lens mounting surface to the sensor surface is 0.492
inches (12.5 mm). It is not possible to use a CS mount lens on a C mount camera.
Q32. What is an Auto-Iris Lens?
A. An auto iris lens provides consistent video signal in areas where light levels vary.
Q33. What is Lux?
A. Illumination is measured in units called Lux. As Lux number decreases, camera’s light sensitivity
increases (most cameras minimum illumination is 0.01).
Q34. What is the automatic Gain Control?
A. Many cameras come with an AGC circuit. This circuit examines the brightness level of the video
signal to keep it at a consistent level. For example, if the video signal is dark, it will attempt to
increase the gain to bring the brightness up to a normal level.
Q35. Explain Aperture?
A. In CCTV optics, the aperture is the diameter of the lens that controls the amount of light reaching
the image sensor. It is shown by an f-number. Larger aperture lenses have smaller f-numbers.
For instance, a lens with an f-number of 1.2 allows more light to reach the sensor than a lens with
an f-number of 2.0 thus producing a brighter image. The higher the f-number the less light is
permitted to pass into the camera.
Q36. Can I zoom in with a camera?
A. Yes, but you need a special camera called a Pan-Tilt-Zoom or PTZ camera. Browse our selection
of PTZ cameras and find the one that is right for you.
Q37. What type of Operating System (OS) does the Security DVR use?
A. Most PC-based Security DVR Systems use Windows 7 Professional, and Standalone Security
DVRs are Linux based.
Q38. What happens if there is power outage?
A. Most Security DVRs will come back on as soon as power is restored. However, we suggest an
uninterruptable power supply (UPS) which provides a short period of backup power and also
serves as a surge protection device.
Q39. Can the Security DVR report an alarm?
A. Yes, some Security DVRs have that option.
Q40. What is the meaning of auto-Iris Control?
A. An automatic iris lens is a lens with a motorized iris that automatically adjusts to only allow a
specific amount of light to reach the image sensor. When there is little light, the iris will open to let
more light in. When there is too much light, the iris will close to reduce the amount of light let in.
Auto iris lenses are primarily used in applications where light levels vary and it would be
impracticable to manually adjust the lens. Automatic iris lenses are generally more efficient than
the electronic shutter since they actually control the amount of light reaching the sensor as
opposed to simply adjusting shutter speed.
Q41. What is the Back Light Compensation?
A. Many cameras include a BLC circuit. This circuit is used to help correct an image with more light
behind the subject being viewed. Without backlight compensation, the subject appears dark with
little detail. Using the backlight compensation will reduce the brightness of the light to allow the
subject to appear brighter and bring out the details.
Q42. Explain EXview HAD?
A. EXview HAD CCD is a trademark of Sony Corporation. The HAD CCD dramatically improves light
efficiency by including near infrared light as a basic structure of the sensor. Conventional CCD
sensors are sensitive to infrared light but are unable to efficiently gather the charge. Because of
this greater efficiency, HAD CCD sensors achieve sensitivities approximately 4 times that of a
conventional CCD.
Q43. What is Infrared referring to?
A. The area below the visible spectrum. B&W cameras are very sensitive to infrared light and allow
the use of infrared illuminators to enhance poorly lit locations without alerting subjects during
surveillance. Color cameras are also sensitive to infrared light, but require an infrared filter to filter
out the red light to keep the image colors.
Q44. What difference between HAD and Super HAD?
A. The Super HAD CCD is a version of Sony’s high performance HAD with improved sensitivity from
the use of more efficient on-chip micro lenses. The Super HAD optimizes the shape of the on-chip
lenses in order to minimize the ineffective area between the lenses on each pixel thereby
minimizing lost light and improving the overall sensitivity per pixel.
Q45. What is the White Balance?
A. For Color cameras only. Different lighting sources provide different color temperatures. The white
balance helps correct these differences by adjusting the color processing to bring the color
temperature to a fixed level. Without this balancing feature, due to the CCD’s poor adaptability,
some colors would appear different (green instead of white in sunlight).
Q46. What are OSD cameras?
A. OSD (On Screen Display) cameras have a menu system within the camera assembly that can be
accessed in order to set functions such as Iris levels, AGC on/off and most features of standard
and advanced cameras.
Q47. Why do I have a clear sharp picture during the day and it is out of focus at night?
A. This is due to the depth of field changing as the light conditions change and can be easily
overcome by following set procedures.
Q48. When can I use a manual iris lens?
A. A general rule of thumb is only to use a MI lens in an internal application. This is because you are
reliant on the electronic circuitry of the camera compensating for light changes in the scene and
this is not able to compensate to the same DEGREE as that of an Auto Iris lens.
Q49. What is the difference between Auto Iris and Direct Drive Lenses?
A. An Auto Iris lens is one that automatically adjusts its iris for changes in the scene lighting levels.
The motor that opens and closes the iris is driven by an Amplifier that processes a small electronic
signal changing with the light level. A Direct Drive 'DD' lens does not have this Amplifier and can
only operate with a camera fitted with one. A camera specification will indicate the available output
Q50. Does the ‘f’ stop matter when choosing a lens?
A. Yes, lenses are usually specified as having a minimum and maximum ‘f’ stop rating; the ‘f’ stop is a
measure of how efficiently the lens allows light from the scene, to pass through the lens and onto
the camera CCD sensor. The maximum aperture (when the lens is fully open), is the minimum ‘f’
stop number and the minimum aperture, (just before the lens completely closes) is the maximum ‘f’
stop number.
A low minimum ‘f’ stop number means that the lens can pass more light through during dark
conditions, which will produce better pictures at night.
A high maximum ‘f’ stop number may be necessary where there is a high level of light or reflection.
This will prevent the camera ‘whiting out’.
