911 security cameras offer a 100% free and detailed site survey to our customers inDallas/ fort worth area. Our digital security camera consultant are very knowledgeable with necessary information that they need to perform a detailed site survey that will give our customers the most of out their security system and help them to secure their business from outside crime and break in, protect in from employee theft, wastes, production, lawsuits and helps the owner control and manage his business remotely from anywhere. During our site survey, our security consultant will meet first to the owners/Manager listen to his complaints and problem areas and then perform a walk through of the place analyzing it and sketching a diagram of the camera location and giving advice on type of system and camera needed with paying close attention to each of the topping listed below:

1. Calculate budget

2. Identify Camera types the proposed number of cameras

3. Decide on the camera style based on the space available and environment.

4. Select the lens and iris type

5. Verify lighting conditions

5. System type: PC based, Standalone or IP NVR (network video recorder)

6. Decide on what cable type (Siamese Vs cat5e) and length you will use

7. Decide on location to centrally locate the monitoring station and power termination.

Budget:

Any project starts with a budget in mind. This helps us from the beginning to work around your budget. Our goal is to maximize your system advantage within your budget. This helps to choose the system type, number and kind of cameras need to be used.

Camera selection:

Cameras come in different shapes, sizes and resolution types to fit specific needs. We Carry high resolution / low resolution / vandal proof, infra red, IP Cameras, Mega Pixel , dual voltage, day and night Pan/Tilt and Zoom and much more. We will recommend to our customer in each case the recommended camera type.

Vandal Proof: 5006SHR

• High Resolution
• 1/3-Inch Sony CCD Sensor
• Digital Signal Processing
• 480 Max TV Lines Resolution
• IP55 Weatherproof Rating
• 60 Feet Zero Lux Illumination
• Compact Housing
• 18 infrared Leds

NOTE: The distances infra-red cameras can see are based upon its illumination capacity. Infra-red cameras have LED’s, which cast out into the darkness. Realistically, a good rule of thumb (but not an absolute) is figure 1 foot for each LED. Therefore, if a camera has 30 LED’s then it probably can see about 30 feet. There are some ov common. You would notice a Cat’s Eye by the extra large size of the LED’s. With respect to infrared quality it has more to do with the intensity of the LED’s and the distance they cover. One thing to note is that infrared LED’s do have a limited life since they are illuminating so they do burn out over time. Covert camera:We recommend a covert camera if our customersuspect a current employee and is interested in catching him in action.

Day and Night Box camera: 2006SHR

• High Resolution
• Color Camera with SONY 1/3″ Super HAD CCD sensor in metal case.
• Employs Digital Signal Processor (DSP) chip-set for image control.
• 480 TVL, 0.2Lux
• High sensitivity, low smear, high anti-blooming, and high S/N ratio.
• Powerful functions: Auto Electronic Shustter (AES), Auto Iris(AI), Back Light Compensation (BLC)
• Supports Auto Iris Lens: both Video-Drive & DC-Drive lens.
• Supports both C and CS mount lens. (Sold separately)
• Built-in anti-aliasing and IR-cut optical filter

Note: Super sensitive Day Night camera with Wide Dynamic Range, 1/3 inch Sony Super Had CCD 540 L color camera. Newly developed DSP provides the wide dynamic range, 120 times of the conventional camera. Dual auto white balance function ensures fidelity color rendition for bright or dark area independently. This camera is made for varying lighting conditions often found in retail stores. The advanced super wide dynamic CCD makes it possible to have a clear image both inside of your business and outside even when the sun is shinning through the front windows or doors. This fully adjustable camera allows you to set up BLC, WB, wide dynamic range and auto electronic shutter speeds for a perfect picture. Use it with your choice of DC or video driven lens. 24 VAC and 12 VDC dual voltages. Box cameras are recommended in mostly all outdoor application and where an optical zoom lens is needed like on top of the cash register or .when trying to read a vehicle license plate. These security cameras are put inside an outdoor weather proof housing. In summery they are used in:

• When mounting to a wall or any vertical area
• When viewing long distances where a long lens is required, which would not fit inside a dome or bullet camera
• When extreme low light conditions are not a consideration

Pan/Tilt/Zoom: 6005 PTZ

• When you want live control of the camera and adjusting the manual pan, tilt or zoom on a fixed cameras is not practical
• When you want to set up a camera to tour the premises
• When you want to view several angles from a single camera

NOTE: Pan, Tilt, Zoom cameras cost anywhere from 5x – 10x the cost of a fixed camera. The Pan, Tilt, Zoom camera cannot record or see where it is not looking. You cannot pan, tilt or zoom after it has been recorded (this can only be done with a 360 degree camera). Making a PTZ camera wireless adds thousands to the cost. PTZ cameras can though perform various functions not possible with a fixed camera. You can control a PTZ camera and zoom in optically up to 36x and beyond digitally up to 12x giving zoom capabilities in the 100’s. The PTZ’s have intelligence and can be programmed to perform pre-defined tours and upon the event of an alarm the camera can swing to a specified location before continuing its tour. An operator can override and take control of the at any time. Lens selection:When selecting a lens, you are trying to determine the area you wish to cover; the width of the shot, and where the central focal point will be.

IP Cameras:

IP cameras are cameras that can connect to your network. IP cameras are extreemly benificial when existing network infrastrycture is present and running new cable is is chalanging. IP cameras are also using in applications where you have multiple building that are not connected together and need to be linked to one NVR recorder.

Lens Selection:

This task is considered very important part of the site survey. What we look for in our site survey are “Hot areas” that our clients points. For example it could an expensive items that our clients need to protect, Exit and entrance points, Production areas, or any other that our clients points to. Other areas you would need to cover over all video.Let’s take, for example, you have a retail shop, and the camera is set up to cover a large area, you may be able to see an incident occur, but not be able to distinguish the facial features because of where it occurred. So, you have one of a few choices – make sure you select a high resolution lens so you have better detail of the image, or select a higher millimeter lens to cover a smaller area, backed up with an additional camera to cover the balance of the target area.There are also some other tricks you can use to minimize costs. You may not have to use a whole slew of cameras, if you know you are going to get a close-up view of a subject elsewhere. For example, if you had a camera at the front entrance to the store, that the subject has to pass through, then you have a good look at them and what they are wearing. So, even if they move about the location elsewhere, you can associate the face you saw at the front door, with the clothing they are wearing seen from a distance.Although there are a myriad of lens sizes, there are a small group that comprise 95% of the market. Typically, they are 2.8mm (wide-angle), 3.6mm, 4mm, 6mm, 8mm fixed lens or a 4mm-9mm, 6~15mm or 6~60mm vari-focal lens. The vari-focal lens gives you the ability to dial in manually anything within the focal range. So, when you install the camera, you would make adjustments until it covers that area you desire. Vari-focal lenses cost significantly more money then the fixed 4, 6, and 8mm lens but the quality is also better. There is a measurable difference. The following screen shots give you an idea of what each lens will look like at certain distances.

Selecting a lens, as well as the number of cameras, at times can be a difficult task because you have a balancing act of trying to keep cost down at the same time as accomplishing your goal. So, do you go with better quality cameras, but fewer of them, or lesser quality cameras but more of them? Although, when you start to add more cameras, the cost of the DVR increases because you require more available channels (channels are ports that cameras plug into on the digital video recorder).So it is all dependent on your budget. We like to try to back into a solution predicated on the budget. This way you have a matching system of quality all the way through, and one that allows for change and growth plans.

When a lens is fixed, understand the image is as you see it. Forget what you see on the television show CSI. Even with a high-end digital video recorder will not get any larger than the original. Can the software increase the size of an image? Absolutely, but when it does so, it pixelates, meaning it gets grainier and less crisp. Don’t believe claims that say they can read a license plate on a speeding car at 100 feet away with a standard lens or what you see in movies. It’s not happening. The only quality you get when enhancing the original is lesser quality.

For low light situations there are two possible camera technology solutions. If there is total darkness then the only possibility is infra-red or otherwise known as night-vision.

Infrared is used in night-vision cameras when there is insufficient visible light to see an object. The camera uses the infrared portion of the electromagnetic spectrum, sometimes referred to as thermal imaging. The radiation is detected and turned into an image, hotter objects showing up in different shades than cooler objects, enabling the camera to see warm targets, such as human beings and automobiles. Infrared technology works great when were there is a lot reflective surfaces like walls/furniture. The light will reflect back at the camera for better picture at zero light situations.

Day/Night technology is a sensitivity enhancement technology which improves light sensitivity of a camera by a factor of 2 for visible light and a factor of 4 for near-infrared wavelengths. It still cannot work in near zero light as will an infrared camera.

While both infrared and day/night technology sound expensive, both have become commercialized and are surprisingly affordable. The difference in camera pricing for one of these cameras versus a traditional camera is nominal.

The rule of thumb we like to use is if you walk the area where you intend for the camera to be and view it at its lowest possible lighting, if you can see with the naked eye, then the day/night camera should be fine. If you cannot see, then an infrared camera would be recommended.

CCTV cameras similar to your movie camera are rated in terms of “lux” for purposes of lighting. In addition to night vision and day/night cameras there are low light cameras, which are standard cameras with a low lux rating (0.1).

Siamese VS Cat5e

Siamese cable which is commonly used in CCTV sometime is replaced with Cat5e when needed. Cat5e is used if you need to transmitt a long distance or when using exsting cable.

System Location:

Keeo in a centralized and secure place if possible. The last you want is to get you camera system stolen.
