Twisted-pair cable transmission video advantage really strengthened we used in the engineering twisted-pair video transmitter's confidence, but in an actual product to choose and wiring applications, or there will be some problems, the paper has a summary, as follows:

1) to enhance anti-jamming ability, to convert the shielded wire. Some friends because of the long-term use of coaxial cables for transmission, put in use the same axis as transmission medium to experience not consciously to apply twisted-pair cable transmission up, think shielded twisted-pair cable in anti-interference more better performance, but actually using shielded wire really strengthened some anti-interference ability, but will the high frequency signal badly damaged, transmission out effect colour becomes poor, distance is not even color images, transmission quality problems. Meanwhile, shielded twisted-pair cable prices high, in the engineering cost increased, so the wiring is first should pay attention to this problem.

2) in order to reduce project costs, and blind choose low-cost products. Any product has its certain reasonable price, good appearance beautiful, mobile phone use conveniently, durable, but the price does not poor, reason lies in its industrial design, quality, materials technology, etc are many work, all this work need to input costs, natural the relative price of some hybrid phones higher. At present our country twisted-pair cable transmission equipment production enterprise to be mostly private small businesses, relatively reasonable price can bring benefits to users, and can ensure the production enterprise have a relatively stable power, not 3, 5 years in hand, we closed the users themselves the product out the problem also do not know to who look for to get it repaired. Twisted-pair cable transmission equipment is in recent years, the market price of a mess, some friends to buy the products after considering the price, when considering first quality and after-sales service, thus putting the cart before the horse. Should be clear, we do engineering is the project, so the whole system, security engineering are reliable quality of products, otherwise quality closes nevertheless, the system itself appeared problems, but also how to monitor kitten doggie 'movement? All want to buy that reliable products, low price is very hard to do, if you bought, maybe will consider this the quality of the products or service quality. Of course, there are some enterprises in the cost control do well, its price is very competitive, but China currently such enterprise rare, so little.

3) blindly believe products waterproof, anti-jamming and lightning protection ability. When the majority of enterprises in the propaganda call their product is waterproof, anti-jamming and lightning protection, therefore and communicating with clients in order to let customers believe our products these ability, put wiring should actively around much rain, strong interference and the direct lightning area, customer purchase products disappear after natural won't pay close attention to these should avoid places, the results may generate interference phenomenon and directly by lightning destroyed phenomenon. Just think, tens of thousands of volts ray can put the tree split into several disc, small twisted-pair cable transmission equipment? ! Chassis will be it melts, the detonator still can have any effect. Therefore, wiring which we must seek truth from facts, try to bypass them, so far so good, at the same time to improve products kept environment, let equipment in a clean, dry environment stable job.

4) rough wiring craft, lead to video the effect not beautiful. In fact, we bought on the market are not shielded twisted-pair cable, but a box 305 meters in engineering point YuanYuanJinJin left a right one, and, therefore, the shorter than 305 meters place needs to break open the flesh of your foreskin; and string pick out the line where camera, long after the two boxes will need even more box connected, the line is the best in wiring, welding, bandage twisted-pair also note the ground and problems, such ability assure transmission is not a problem. Online

5) go two extreme, cause unnecessary waste. With long distance transmission equipment used in short, and use short transmission equipment used in a great distance is not scientific. Some friends to make video effect is better, often at the cost of transmission equipment will be 1200 m using in 500 meters, actually do need not, is kind of a waste. In short, the products have a more saving some don't need the power, stability, stronger, very economy, in the shortage of energy today, we advocate efficiently save. Conversely, if the normal work of the equipment used in 300 meters in 500 meters, is not scientific, called a 10-year-old kids pick 100 jins burden can into it, such doing can increase the risk of damage to the equipment, show the effect of the badly.

6) wire was so bad, cause often disconnected. Twisted-pair cable video transmission equipment in wiring mostly take both when wiring way, one kind is the direct took a line through two line after receiving equipment were carrying two terminals; One kind is to use RJ45 crystal head to meet. Both methods have their advantages and disadvantages, with the way the tweeters at contact among nodes is good, can good contacts, but to ensure the line twisted-pair fine, no special tools not easy processing, if wire quality is bad, pushing wires can be very brittle, can not stand tossing; Using crystal head to meet, let a person feel very can *, but the actual effect is bad, because the crystalline head contact * elastic compression, a long time may cause contact undesirable. In addition, general a point we only four pairs of twisted-pair couple, if the line of line it four head, apparently crystal a waste. Therefore, the best way is to still take the form of tweeters, but, in purchasing wire of good quality, brand wire chosen as more as possible. Some worry that the use of form, tweeters wiring two lines thin whether can afford more long term itself weight pulling, fears that produced was normal, but we have to deal with it, as long as the entire head in wiring near root twisted-pair cable do a fixed, such worry can completely solved.

7) research is not deep, patience is insufficient, failed to adjust the best effect. First used twisted-pair cable transmission equipment, see thin thin one-page manual think is a piece of cake, so rough installation looked at the instruction, you will start, but actual adjustment found far, because it's not that when transmitters and receivers adjust to adjust, while emitter location in 100 kilometers away, often with interphone on both sides of the personnel need to coordinate, this work constantly disturbing, therefore problem is easy to produce, many first-time users, it is easy to turn their anger on twisted-pair cable transmission equipment. The solution to this problem is, concrete construction personnel first, secondly, to read through manual according to actual estimate about the distance between two points, to determine the dial the code position, launched the construction personnel that receive again the appropriate adjustment, if not, explain estimate incorrectly, will reevaluate, set on launch after the dial the code, the receiving end personnel again adjustment, so, the best effect easily adjustable out. The key lies in 1, wants be particular about a adjusting order, 2, to embrace study attitude, patience, comprehensive, seriously do it again.
