Coming with detachable lenses, C-mount cameras allow for simple lens changes to fit different applications. C-mount cameras can cover distances beyond 40 ft thanks to the possibility to use special lenses with these cameras, whereas standard CCTV lenses can only cover distances of 35-40 ft.
ANPR and LPR cameras are used to read and store data on registration plates. They offer a simple and efficient solution to many organisations including tolling, hotel overstay management and the obvious: car parking. ANRP stands for Automatic Number Plate Recognition (LPR cameras stands for License plate cameras) and these devices help to obtain copious information in a high traffic area to keep any premises secure.
Whether you’re looking to install a CCTV camera outside a property to catch criminal activity, or have placed one inside to monitor the home or a company’s goods, there’s something for everyone.

Conclusion Light duration, spectrum and intensity are critical for optimum peaks and sustained egg production. While there are many choices in lighting available to the poultry producer, LED lights are becoming increasingly popular due to the combination of energy efficiency, reliability and long bulb life. As the use of LED lights increases, the understanding of proper application in various housing types will increase. Lower product costs and improved efficiency and application of LED lights can be expected in the future.

These cameras share the images across the internet, so CCTV footage can be easily accessed. Network cameras are ideal for both domestic and commercial purposes because you can see what’s going on whilst away from the property.
Capable of operating in both normal and poorly lit environments, these cameras benefit from not requiring inbuilt infrared illuminators as they can capture clear video images in the dark thanks to their extra sensitive imaging chips. For this reason, these cameras are ideal for outdoor surveillance applications in which IR cameras are unable to function optimally.
Audio isn’t required, however, if you do wish to opt for audio there are systems where you can speak to a person who has broken into the property. Audio can be used to deter criminals by automatically playing something when they get a certain point inside, an ideal way to make them think that there are people inside the building.

Choosing the best LED bulb for your chicken house Selecting the right LED light bulb can be difficult once the decision to retrofit or build has been made. There are three classes of LED bulbs currently available:
Understanding lumens and directionality for different poultry systems In colony cages, select a directional light that illuminates the scratch pad and feed/water lines, while leaving the nest in shadow. When LED lights are hung in the aisle outside cages, an appropriate directional light will provide uniform light intensity to all tiers of cages, as shown in the Figure. The lumen output of a light does not account for the peak wavelength spectrum. For example, two LED lights that are both listed at 800 lumens may elicit different responses from chickens if the color spectra of the lights are different. While using chromaticity (K) can help separate different lights with similar luminosity, this measurement does not accurately account for the full spectral quality of the light.
What many people don’t know, however, is that there are a variety of different types of CCTV camera which suit different situations or premises, and that selecting the proper camera for the right application really is vital.

Having more detail will, of course, help in all situations, because it means that you will be able to see exactly what’s happening and get a clear record on film. A zoom lense can provide customers with more information because optical zoom can adjust the light as it reaches the sensor, enabling flexibility and enhanced pictures.
Use of LED lights for poultry LED lights are becoming more common for use with poultry around the world because they are energy-efficient, full-spectrum and long-lasting.

Dimming LED Lights Dimmers need to be compatible with the specific LED lights installed and used with an LED bulb that is rated for dimming. Incompatible dimmers may cause LED lights to flicker, overheat or burn out more quickly. LED lights do not have a resistive filament like an incandescent bulb, and require dimmers to be able to handle the complex electrical load to control wattage output. Not all LED lights are designed to be dimmable, and not all dimmable LED lights will work exactly as intended. A good dimmable LED light requires the right equipment to dim even with a proper LED dimmer. A good LED dimmer will have resistance built into the dimmer to ensure consistent performance when dimmed. LED lights maintain efficiency when dimmed, and may increase the bulb life. Work with the LED manufacturer to ensure you have the correct dimmer installed. Incandescent and LED dimmers both operate similarly; however, LED dimmers must have greater control of wattage output. If a dimmer turned to 50% is fluctuating + / – 3 watts, a 60-watt incandescent bulb will jump in power usage from 27 to 33 watts, which may not be perceptible to the human eye. The same dimmer fluctuating for a 10-watt LED bulb will cause the difference in power usage to jump between 2 and 8 watts. This extreme change in power going into the light will cause noticeable flickering. Additionally, even small fluctuations in power will cause dimmed LED lights to flicker.
Box cameras present an obvious sign for anyone who passes by that they are being recorded on CCTV and this can be a great deterrent of theft and crime. Whereas dome cameras are smaller and more discreet. These compact cameras are ideal for monitoring a larger area such as your front or back garden and can follow movement with ease.
When it comes to securing your business, there are many different types of CCTV to choose from. Surveillance plays a huge part in today’s society, and with cameras all around us, our day-to-day lives are experiencing higher levels of security each day.
PTZ – Pan/tilt/zoom – cameras allow the camera to be moved left or right (panning), up and down (tilting) and even allow the lens to be zoomed closer or farther. These cameras are used in situations where a live guard or surveillance specialist is there operating the security systems.
The importance of lens diffusion The light emitted from an LED bulb is inherently directional, and may create shadows when there is poor lens diffusion or placement in the poultry house. While achieving a light angle output of less than 180° can be beneficial in directing light toward the birds, the spacing of the lights must be appropriate to avoid shadows. Lights hung too low or with a beam angle of less than 120° produce the effect of “spotlighting,” where cones of light and dark areas are created in the house. While these lights can be utilized effectively, spotlighting can be minimized by careful placement and spacing of the lights. Uneven light distribution is an issue in both floor and cage housing systems. In floor houses, uneven lighting causes shadows, creating nesting areas for birds and resulting in higher levels of floor eggs. In cage or colony houses, uneven light distribution may cause some cages to have too much or too little light, leading to both over and under stimulation in the same house. LED lights do not emit as much heat as incandescent or fluorescent lights; therefore, plastic or polycarbonate materials can be utilized for the lens and diffuser. While the newer generation LED lights have better light diffusion, it is still important to understand the directional light output of LED bulbs when planning your lighting system, taking into account the placement, light intensity and intended usage. Most LED manufacturers have computer programs to assess the distance, height and lumen output required to adequately light any facility.
Luminous flux is the total emitted visible light from a bulb, measured in lumens. Luminous intensity (directional flux) quantifies the luminous flux emitted by a light source in a certain direction, measured in candelas or candles. Luminous power is the luminous flux per area illuminated by the light, measured in lux or foot candles (fc). The calculation is 1 lux = 1 lumen/mq or 1 lux = 0.0929 fc (lumen/mq). The conversion between the two units is 1 fc = 10.76 lux or 1 lux = 0.0929 fc; this is equal to the conversion between 1 square meter (mq) and 1 square foot (ftq) (i.e. 1 mq = 10.76 ftq). This means that the same light will be brighter closer to the light source, and dimmer farther away as the beam spreads out.

These types of cameras allow for discreet placement which means you can capture good footage of theft and criminal damage. Discreet CCTV cameras beneficial because criminals will be less likely to spot them and therefore, they are less likely to be damaged in the process.
Understanding lumens to assess a light bulb With incandescent lights, the luminal output in relation to the wattage of the bulb is consistent across manufacturers. Most traditional incandescent bulbs are sold in 40, 60, 75 and 100-watt versions. With the introduction of compact fluorescent lights and now LED bulbs, most light manufacturers still relate the luminous flux of the bulb back to an incandescent wattage equivalent. The equivalence between CFL bulbs and incandescent bulbs is valid because both types of bulbs emit light evenly. However, LED light is more directional, and using lumens may not be accurate. Wattage and other factors, such as desired light direction, light color spectrum and intended light usage, should be considered. Luminous flux assesses the total light output of a bulb without any regard to direction; however, many LED lights can emit light with an angle of dispersion of 30° to 180° or greater, based on heat sink fins, diode direction and general construction. Two identical lights—one directional (i.e. LED) and the other with global output (i.e. CFL)—can have the same luminous flux, but depending on the location in relation to the bulb, will have very different candle and illuminance power.

This will ensure that you receive a quality image. Choosing the right lens will allow your camera to focus and will bring enough light to the sensor on the camera, helping you to read registration plates and recognise faces etc.
Electrical requirements for led lights Wiring LED lights may require different electrical wiring in a house. Some states and countries ban the use of screw-type sockets that are not water-tight and instead require that lights be wired directly into junction boxes. Check local regulations before installing or retrofitting a house for LED lights.
Test different camera models to see what works best with the lightning in your area, because no matter whether they’re inside or outside, the lighting will differ throughout the day. You will want to check any reflections and backlighting during the day and night.
The more pixels, the better the picture. The highest resolution you can get is 700TVL but many mainstream cameras range between 300-550TVL. It’s important to match a resolution that your camera can produce, anything more is completely unnecessary.
These cameras can pick up coloured images in very low-light conditions. Dark fighter technology can be used in the day and night and offer optimal performance thanks to its wide range of capabilities. They are equipped with ½” CMOS progressive scan sensors which allows the device to pick up high-quality images and doesn’t require an extra light source – which makes the perfect night time security surveillance camera.
When thinking where you would like to place your cameras, you might want to think about how they will be mounted and housed, in order to ensure that they’re in the best location and well protected. For example, if your camera is to be placed outside, you will want it to be robust and weather proofed. If it’s to be placed indoors you will want to ensure it will not be affected by grease or steam from a kitchen.

Light intensity can be measured in three ways: luminous intensity, luminous flux and luminous power. Led Lights are here analyzed.
Light meters Traditional light meters are calibrated for the human spectral response at a white color temperature with a spectrum between 550–560 nm. These light meters are unable to assess blue or red spectrum and cannot calculate the difference in light response between humans and poultry. It is important to be able to observe light intensity in both the visible blue and visible red spectra due to the chicken’s wider visible light spectrum. Ideal light meters for assessing LED bulbs are either poultry-specific light meters or LED-specific light meters. Poultry-specific light meters are able to calculate the effective light intensity as observed by a chicken (clux), while LED-specific light meters are able to analyze the full spectral output of the light for human vision. Only a few companies make poultry-specific light meters, while LED light meters are used by photographers and are available from several sources.
With the ability to zoom in and out without forfeiting its focus. Varifocal cameras allow you to adjust the focal length, the angle and increase or decrease the zoom – ideal for obtaining footage in a square room where you would normally experience a ‘dead zone’ with any alternative, fixed lense camera.
