DCS-7410 Business AnalysisWhy we development this model :

The technology of traditional outdoor CCTV camera is in the mature and intact phase, it is a good opportunity for enter this market that we want to integrate these characters with our IP module to accomplish in possession of this product line, also complete all of our products position.

Overcome the various weather in outdoor.

Model Description： DCS-7410 is the outdoor network cameras with IR LEDs for outdoor

surveillance applications and detail remote monitoring. It is weatherproof - so it can be used inside and out. And it's infrared - thus it can see during the day and night.

Selling Point： This is a super high resolution weatherproof wired CCD camera with built-in IR LEDs. The IR camera can operate in total darkness to enable surveillance day and night. IR camera in weatherproof aluminum casing with a detachable sun shield. High resolution SONY CCD 520 TV lines image sensor produces excellent color video in the day and automatically turns to B/W mode in the night. Can operate in total darkness for distance up to 98 feet (30 meters). The built-in infrared LEDs turn on automatically when the light condition turns weak. DI / DO interface 3GPP mobile surveillance The Motion JPEG and MPEG-4 streams simultaneous allows systems to be optimized for both image quality and bandwidth-efficiency.

(Day & Night)

• Day & Night solution

Solution 1: With dual-band filter, cameras can with at day time for visible light as well as night time for IR light (This IR light will required extra IR LED illuminator). This is most entry level solution, it can work both day and night time but sometimes its side effect might affect picture color of day time.

Solution 2: With ICR (Infrared-Cut Removable filter) module, it use 2 filters for day and night time, it can get better color performance but cost higher.

Solution 3: Camera built-in IR LED for illumination and dual-band or ICR filter, this is most advance function camera. We usually call it All-in-one camera.

IR led is usually used for night surveillance, camera need to allow IR light pass thru sensor to get night vision.

New features of Day & Night solution - solution

Light is a form of radiation wave energy that exists in a spectrum. The human eye can see, however, only a portion (between wavelengths of ~400 – 700 nanometers or nm). Below blue, just outside the range humans can see, is ultraviolet light, and above red is infrared light.      

• Light perception

Day & Night solution – About Light

– Coating allows only visible light to pass through– Can’t see anything in night mode

• IR cut coating in all “day time” camera

Day & Night solution – IR cut filter

Dual band coating to allow visible light and IR illumination to pass through

This is the filter glass.

• Dual band coating (DCS-7410 use this solution)

New features of Day & Night solution – Dual band

– Sensors respond to both visible light and infrared light– White balance algorithm will be affected by the infrared– Image have color problem in strong IR light environment

– Remove IR-cut filter in night time will get best results– True day and night– But more expensive

• ICR (IR-Cut Removable) Lens (DCS-7510 use this solution)

• Problem of dual band coating

(IP66 norm)

• The European Committee for Electro technical Standardization developed the Ingress Protection (IP) ratings (CENELEC) (described IEC/EN 60529), this specifies the protection a piece of electrical equipment or enclosures provides from the environment.

• The way in which the index and classification works is as follows: The IP will be made up of two numbers – The first states the level of mechanical protection from thing such as dust and other

solid objects. – The second number indicates the degree of protection from water and other liquids.

• An example of this would be with an IP code 66. It is supposed to be total protection against dust, and also against heavy water spray.

New features of Network camera - What is IP66?

IP First number - Protection against solid objects0 No protection.1 Protected against solid objects up to 50mm, e.g. accidental touch by hands.2 Protected against solid objects up to 12mm, e.g. fingers.3 Protected against solid objects over 2.5mm (tools and wires).4 Protected against solid objects over 1mm (tools, wire, and small wires).5 Protected against dust limited ingress (no harmful deposit).6 Totally protected against dust.

IP Second number - Protection against liquids 0 No protection.1 Protection against vertically falling drops of water e.g. condensation.2 Protection against direct sprays of water up to 15° from the vertical.3 Protected against direct sprays of water up to 60° from the vertical.4 Protection against water sprayed from all directions. limited ingress permitted.5 Protected against low pressure jets of water from all directions. limited ingress.6 Protected against low pressure jets of water, e.g. for use on ship decks - limited ingress permitted.7 Protected against the effect of immersion between 15cm and 1m.8 Protects against long periods of immersion under pressure.

• Both DCS-7410 and DCS-7510 use a optical condenser, the distance of IR can reach up to two times than without.

• This design can reduce power consumption of IR LED and enhance the illumination coverage.

Dual-band filter Performance

At day time, the color will be affected by IR light at certain circumstances.

At night time, the filter can allow the built-in IR light pass thru the lens. So it is suitable for day and night surveillance.

ICR filter Performance

At day time, with ICR the picture quality is perfect.

At night time, ICR can also allow the built-in IR light pass thru the lens. So it is suitable for day and night surveillance
