The same recording is accessible later for deterring theft, mischief or any illegal activities in area. The CCTV Recording can also be used for business enhancement purpose and training purpose. Today CCTV is need of merely every place because world is not secure and trustworthy as it used to be.
What is CCD Camera and how they are better than CMOS Chinese camera?
CCD stands for “Charge Coupled Device”. CCD is latest technology in CCTV Analogue display and provides clear and crystal images. CCD cameras also give picture under low light. CMOS is very old technology it has remained to market only because of its cheap price.
CMOS vs. CCD
Most cheap cameras sold are using CMOS sensors, unless specified as CCD. CCD technology is better and produces sharper resolution color reproductions. E.g. lower cost mobile phones are using CMOS sensors, while an expensive digital camera uses CCD sensors. This is not typical CMOS CHINESE camera which is sold by some vendors. This is CCD (Charged Coupled Device) Color Camera. The Core component of camera is its CCD (Image Processor) it’s like your computer where you identify the computer performance by Celeron, Pentium 4 etc. The CCD is the image sensor of camera where image is captured and processed; therefore the clarity and resolution of captured images entirely depend on that. The Image quality of this CCD camera is thousand times better than CMOS Chinese cameras.
What are the types of CCTV CCD Camera and where they are used?
The following are the type of CCD Camera.
Dome CCD Camera:
CCD camera is either fitted in Dome (Ceiling Fitting) or in Metal Cabinet (wall mount) are used in Office, Garage, Workshop, Supermarket, Parking Area merely everywhere where area of surveillance is fixed.
C/CS Mount CCD Camera:
C/CS Mount cameras are used for enhancing the clarity, distance, lighting, backlight, zoom etc. by adding specific lens.
Infrared Night vision CCD Camera:

How to determine good camera from others?
CCTV cameras are determined with their resolution in terms of TV Lines. 350 -400 TV Lines >> Normal Resolution 420-520 TV Lines >> High Resolution 600 & more >> Superfine Resolution.
What is Night Vision Camera?
Night vision cameras are used for night surveillance. Infrared camera works as color camera during daytime and black & white during nights. The IR LED’s turns on automatically upon low light.
Where to use Infrared Dome and Where to use Infrared Box Camera?
Dome Infrared is used in Office, Garage or Indoor locations. The BOX Infrared cameras are used in warehouse, outdoor. The simple understanding is Dome if for Ceiling Mount and Box Camera is for wall mount.
What does the no. of LED's represent in Infrared Night vision camera?
The number of LED’s represents the distance covered. More the number of LED’s wider and deeper the coverage.
Dome Camera V/S C-Mount Camera?
There is no basic difference unless TV Lines mentioned different between Dome and C-Mount camera. As specified earlier the Camera clarity depends on TV Lines. C-Mount cameras are used if you want to attach enhanced lens like Varifocal, Auto Iris, and Zoom etc.
Do I need to use C-Mount camera for wall mounting purpose only?
For the purpose of wall-mounting, you can use Mini Metal cabinet in lieu of Dome and use the Board CCD camera which are used in Dome camera or wall mount.
Where & Why to use C-Mount of Box Camera?
C-Mount cameras is used for the purpose of Auto Iris, Varifocal and Zoom lens addition.
What is the purpose of Auto Iris lens and Varifocal lens?
Auto Iris lens give clear and uniform images in every lighting conditions. It is used where lighting conditions varies time to time. If Clear and crystal images are essential in that particular area then one can go for Auto Iris Lens. Varifocal lens are used where area coverage needs to be changed frequently. For e.g. on one occasion you require to cover entire gate and on other you need to only cover entry of vehicles with their number plate. So with Varifocal lens you can adjust the focal point and concentrate particular area.
What is Outdoor Housing & where it is used?
Outdoor housing is used in case when a camera are prone to dust, wind, rain showers, sunlight etc. According to the nature of mounting one can select the suitable outdoor housing
What are IP Camera & how they are different from CCD camera?
IP cameras are the latest innovation in CCTV Industry and have changed the way Surveillance systems are handled. All over the world major new Turn Key projects are installed using IP cameras only due to their flexibility, easy operations & Central Monitoring adaptability without any additional hardware. As they are in entry level yet the costing is higher compare to typical analog camera, thus it’s penetration in the small to medium sized enterprises and home security is very minimal. IP Camera produces digital images, which are easy to store/manage/manipulate. Normal CCTV camera produces Analog images which are then processed by additional devices like DVR for storage and processing.
What is Pin Hole camera?
Pin Cameras are useful for cover surveillance operations. Please check your local rules and regulations before purchasing.
What are Spy cameras with DVR?

What is the difference between MPEG4 & H.264 Hardware Compression DVR cards?
H.264 is latest technology. Like mobile phones, the latest versions are more powerful and have more features then older ones. The purpose of surveillance is fulfilled in both technologies.
What is the difference between Software Compression and Hardware Compression?
Software Compression consumes more PC resources for compressing images and requires more space to store recording in Harddisk. For Remote Viewing over Internet, because of the bigger images sizes the less frames are viewed on remote site compare to hardware compression. Hardware Compression uses its own codec and hardware to compress the images making them best possible size without compromising quality. Requires less harddisk size and remove viewing gives more frames compare to software compression cards. Hardware Compression 10 days recording = Software Compression 6 days recording. Note: Today the Harddisk are available at very cheap rate so can add additional hard disk for more days of storage. The only major factor for choosing Hardware Compression DVR card is for Remote Viewing. If Remote Viewing is essential and more number of frames is required on remote site then one can go for Hardware Compression cards.
What is the difference between PC Based DVR and Standalone DVR?
PC Based DVR are PCI cards which get installed in Computer System. The Cameras are then connected to DVR card. The Software is supplied with the DVR card. This runs on Computer system and records all the moves of connected cameras to computer harddisk in desired mode. Standalone DVR is Independent Device which has its own hardware specifically designed to record/play/broadcast/manager camera videos. A harddisk is also installed in standalone DVR.
The comparison is given below:
PC-Based DVR Standalone DVR The cost is very reasonable compare to Standalone. About 30 %( PC required) The cost is higher. (PC not required) Easy to upgrade and increase the number of camera. No need to replace hardware. Just add more cards. To increase the camera or upgrade, the whole hardware unit needs to be replaced and you get nothing by reselling the old. Can add any number of Hard disk in computer. So increasing storage capacity is never a problem. Has limited number of slots for Hard disk attachment. The PC interface is easier to understand, operate and manage. The product has manual and it’s easy to learn the functions. In case of any non-repairable problem, only the DVR cards are needed to be replaced. The whole Unit is replaced for non-repairable problem. Again costlier to replace. Major role of recording/storing is handled by PC so maintenance and repairing is easy and economical. The whole system is integrated. A small error may lead surrendering product for repairing. Small Units. Easy to carry and Install. Big DVD type units. No yearly maintenance contracts. Need not pay extra for maintenance every year for service or just cleaning hardware. Extra care is required to maintain the unit from Dust & humidity. For cleaning or just blowing air the Vendor may charge hefty annual maintenance contract. If you have PC which can be spared, then Best Solution If you do not have PC then Better option.
How to connect a PTZ camera to a DVR?
To connect a PTZ camera to a DVR, you need three cable pairs: coax for video, twisted pair for the RS485 command interface, and the power supply. The twisted pair should be at least 22 Gauge, and if these cables are to be installed outdoor or there are electrical appliances nearby, please make sure they are shielded in conduits.
Before you start the installation, please set the PTZ camera to the appropriate protocol, baud rate, and camera ID, e.g. Pelco “D”, 2400bps, camera ID 1,2,3,,,,etc. Of course, all PTZ camera IDs on the same system has to be distinct. Then set up the DVR software to match your camera settings, and to map the camera inputs with the corresponding IDs.
If you are installing multiple PTZ cameras on one DVR system, please be careful of the wiring scheme for RS485 interface. There are two ways:
1. Star network: all twisted pairs would run from one interface converter (RS-1, RS2, GV net) direct to the PTZ cameras. Please sure that the polarity for the twisted pair is right. The longest run cable would have to be terminated with a resistor, which is a simple setting in the ILDVR Speed dome. Try NOT to splice the cable that runs from the DVR to the camera..
2. Daisy chain: Run the twisted pair from the RS485 interface on the DVR to the closest camera, then, from this camera to the next, and to another till you get to the furthest camera At the furthest camera, terminate the cable with a resistor, which, in the case of ILDVR speed dome, is a simple setting.
Try not to mix up the wiring scheme, and not to splice the cable runs. In this way, you can daisy chain as many speed domes as you want for one DVR. Contact Bern Clare Multimedia Inc. (905)-513-2722 should you need more information on the above. We have years of experience in PTZ camera selection and installation.
What is the difference between Real-time & Non-Real-time DVR?
CReal-time DVR stores recording in full frames (i.e. 25 Frames per Second) for each camera. The recording is played as you watch movie or TV shows. In Non-Real-time DVR the recording is done for less than 25 Frames per camera adjusted against number of camera and total frames capacity of DVR. Non real-time recording plays like you are watching slow motion.
What is BNC and how it is connected?
BNC extends as Bayonet Neill Concelman connector, (sometimes erroneously called a British Naval Connector or Bayonet Nut Connector, a type of connector used with coaxial cables such as the RG-58 A/U cable used with the 10Base-2 Ethernet system. The basic BNC connector is a male type mounted at each end of a cable. This connector has a center pin connected to the center cable conductor and a metal tube connected to the outer cable shield. A rotating ring outside the tube locks the cable to any female connector.
