 They know what it is and what the purpose of such device is. So whenever someone sees such a camera outside your building, or inside, they know that you’re protecting your property. Believe it or not, bullet-type security cameras prevent thieves from taking action. But, you couldn’t say the same about dome security cameras.
Dome cameras are used for the same reason as any security camera; however, the design of a dome camera is very different.
Dome cameras look like’ well – dome. That’s why they’re called this way. Not everybody is used to such type of security cameras. So if you need a powerful security camera that doesn’t attract so much attention, then a dome camera is your choice. Such cameras are usually installed in casinos or other interior environment where they shouldn’t make much suspicion.
Now dummy cameras have only one purpose – to fool someone. See, a dummy camera means that it’s fake. Such cameras may look like real ones, even have some LEDs and wires, but they do not monitor anything.
Dummy cameras are very cheap compared to real ones. Yes, it might be a good idea to set one up outdoor to prevent burglary. But what about a real protection, when a picture of a burglar could uncover a serious crime?
You might use one or few such dummy cameras somewhere. But you need to have real cameras in place if you want to actually monitor and protect your company’s equipment.
You’ve probably heard about DVR (digital video recorder). It’s a system widely used in security industry these days. DVR can record a video captured from security cameras into a HDD (hard drive) or a special DVR device.
Many businesses still use VCR’s (regular video recorders) to record video from wired or wireless security cameras. VCR’s are cheaper, but do not provide such quality as DVR’s. You cannot compare VHS tape video quality with digital videos. Digital video recorders capture many times better quality images than VCR’s. And if you need detailed view, then you should definitely choose a DVR security system.
The biggest advantage of a DVR security system is that it doesn’t need any tapes. With old VCR’s, you’d need to store all the tapes somewhere. And if you overwrite those tapes, then the quality of the image gets worse. VHS tapes ware off over time and the valuable data may be lost. It doesn’t happen with DVR’s.
You can store many gigabytes of data in your hard drive. You can have more than one hard drive to have even bigger capacity. You may easily record some videos into DVD’s and keep them for later use if you need. DVR wireless security camera systems have much better search options. If you need to search for a particular event, you may do so in seconds.
PC based or Embedded DVR Security Systems?
PC based wireless security camera systems are flexible. In some cases, you may change the FPS rate, resolution and quality using software. Such DVR systems use a special DVR card that is installed into a PC (like any other PCI card).
However, embedded DVR security systems are different.
Embedded wireless security camera system looks like a regular DVD player. They aren’t very large, but are very powerful. Such embedded DVR’s have no hack threats. They don’t crash, because they usually use Linux operating systems.
Embedded DVR systems cost more than VCR, but they also provide more options and better quality videos. In such case, you shouldn’t save money on older systems like VCR. New DVR’s are preferred choice by many companies, because they automate your tasks much better and produce higher resolution videos.

Trematodes (flukes) include parasitic flatworms belonging to the phylum Platyhelminthes, class Trematoda, and subclasses Aspidogastrea (two orders, four families) and Digenea (ten orders, more than seventy-two families). The class numbers between 18,000 and 24,000 species; they are found primarily in a variety of animals, including humans and other vertebrates. Modern phylogenetic analysis reveals that the worms of class Monogenoidea (monogenetic flukes) are no longer included within the Trematoda and are more closely related to tapeworms. The modern mobility of human beings, combined with the international transportation of animals and foodstuffs that can be infected, means that diagnoses can occur well outside the areas where trematode species are endemic. However, while trematodes do occur in Arkansas, they do not pose a great health risk, as they primarily occur in species of animals not commonly eaten by humans.
One small group of trematodes belongs to the subclass Aspidogastrea (sometimes referred to as Aspidobothrea), which includes about eighty species. They are parasites of mollusks but can also infect fishes (including both teleost and cartilaginous species) and turtles. Specific cartilaginous hosts of aspidogastreans include chondrichthyan fishes (sharks, rays, and chimaeras), a group that is 450 million years old, whereas those of the sister group of the aspidogastreans, the digeneans, are known from both condrichthyan and teleost fishes (210 million years old) as well as from various “higher” vertebrates.
Species range in length from less than one millimeter to over several centimeters. Aspidogastreans have a less complex life cycle than their digenean relatives, and reproduction results in only one egg. These eggs are laid and passed out of the host with the host’s feces, and in some, such as Amphilina foliacea from sturgeon, the eggs do not hatch until they are eaten by the amphipod intermediate host. In others, such as Austramphilina elongata from the long-necked turtle (Chelodina longicollis) in southeastern Australia, they hatch in the water and the larvae swim around until they are able to infect a suitable, or sometimes unsuitable, host. In some species—such as Aspidogaster conchicola from freshwater mussels and Lobatostoma manteri from the snubnosed dart (Trachinotus blochi) of the Great Barrier Reef—the eggs are not laid until the larvae are nearly ready to hatch. These larvae can be either ciliated (having hairlike projections), in which case they normally have two rings of cilia (i.e., Multicotyle purvisi from freshwater snails and turtles in southeastern Asia and Cotylogaster occidentalis from freshwater drum, Aplodinotus grunniens), or they can be unciliated as in Rugogaster hydrolagi from rectal glands of holocephalan fishes and Multicalyx elegans from the intestine of holocephalans and elasmobranchs.
In the intermediate host, the larvae grow a certain amount and then wait until the intermediate host is eaten by the primary host. Interestingly, aspidogastreans may survive for many days or perhaps even weeks outside a host in water or saline solution. This evidence has led some to propose that aspidogastreans are archaic trematodes, not yet well adapted to specific hosts, that have given rise to the more “advanced” digenean trematodes. They further propose that the complex life cycles of digenean trematodes have evolved from the unsophisticated ones of aspidogastreans. However, because none of these aspidogastreans have medical or economic importance, they attract little attention compared to the Digenea.
The more common flukes of the subclass Digenea are mostly dorsoventrally flattened (flattened on the top and bottom surfaces) and possess a muscular oral sucker that surrounds the mouth. In addition, most also possess a midventral or posterior acetabulum (ventral sucker) used for locomotion and attachment to a host. The digestive tract normally consists of a short esophagus (often surrounded by a
