在燕屋農場里的閉路電視 CCTVs in SWIFTLETS FARMS














我的一些學生詢問是否在燕屋農場安裝閉路電視會對燕子造成傷害。

我以前寫過這篇文章,也許是78年前在我以前的文章。 www.swiftletfarmer.blogspot.com

安裝CCTV在燕屋農場的原因是為了觀察燕屋農場中燕子的時刻和活動。從閉路電視我們可以觀察和研究實際停留的燕子數量,它們如何進入燕屋農場,任何掠食者進入以及盜賊等入侵者。

今天市場上有很多閉路電視。我們知道燕屋農場的內部環境總是很暗,所以選擇合適的閉路電視是非常重要的。它必須能夠在黑暗的封閉區域中良好地工作,以在低光照條件下捕獲視頻或圖像。為此,CCTV必須具備IR功能(IRInfra-Red)。紅外閉路電視可以在低光條件下捕捉高分辨率圖片和視頻,而正常的閉路電視是無法做到的。

但是,有一個挫折。讓我解釋。一些紅外功能閉路電視在打開時有紅燈指示燈。這些紅光指示器類似於捕食者的眼睛,尤其是貓頭鷹和老鷹。

貓頭鷹和老鷹是從伏擊中捕獵的掠食者。它們通常隱藏在燕屋農場內的邊緣(外部)。聰明而有經驗的燕子知道這一點。掠食者的任何跡像都會阻止他們留在燕屋農場。閉路電視通常安裝在环绕區,做窝區等的邊緣,以便覆蓋更大的觀看區域。經常安裝閉路電視的地方也是掠奪者喜歡棲息的地方。

您可以觀察到的一個跡像是,當燕子朝著第二個入口洞靠近环绕區時突然轉回。這表明他們害怕或者他們看到了一些不對的東西。這對新的燕屋農場來說是很不利的,因為燕子需要很長時間才能留下做燕窝。

因此,選擇合適的CCTV在您的燕屋農場使用是非常重要。找到那些打開時沒有紅燈指示燈的那些。市場上有很多。找一個具有紅外功能但沒有紅燈模式,否則當燕子以速度飛入時你只能看到一個影子。


最好就是分享。記住,學習正確的方法。不要盲目跟从

CCTVs in SWIFTLETS FARMS









Some of my students have asked whether installing CCTVs in Swiftlets Farm would do harm to the Swiftlets.

 I had written about this before, perhaps 7 or 8 years ago in my previous articles. (www.swiftletfarmer.blogspot.com)

The reason CCTV is installed in Swiftlets Farm is to observe the moments and the activities of Swiftlets in the farm. From the CCTVs we could observe and study how many birds actually stayed, how they entered the farm, any predators entered and also intruders like thieves, etc.

There are many CCTVs in the market today. As we know the internal environment of a Swiftlet farm is always dark, so choosing the right CCTV is utmost important. It must be able to function well in the dark enclosed areas to capture videos or images in low light condition.  In order to do that the CCTV must have the IR capability (IR: Infra-Red). IR CCTV could capture high resolution pictures and videos in low light condition where as normal CCTV couldn’t do.

But, there is a setback. Let me explain. Some IR capability CCTVs have Red light indicators when switched on. These Red light indicators resemble the eyes of predators, especially Owls and Eagles.

Owls and Eagles are predators that hunt from an ambush. Often they hide at the edges inside the farms (Outside). Smart and experienced Swiftlets knew this. Any sign of the predators would deter them from staying in the farm. CCTVs are often installed at the edges of the Roving areas, Nesting areas, etc so as to cover a bigger viewing area possible. The places where the CCTVs are installed often are also the places where the Predators like to perch.

One of the indications that you could observe is when the birds make a sudden turn back as they approaching the Roving area towards the second Entrance Hole. This showed that they are afraid or they had seen something which is not right.  This is bad for New Swiftlets farms as it would take a very long time for birds to stay and build nests.

So choosing a right CCTV to use in your Swiftlet farm is important. Find those that don’t have the Red light indicators when switch on. There are many in the market. Find one that has IR capability but without the Red light mode otherwise when the birds fly in with speed you could only see nothing but a shadow.

帮助失败的燕屋农场在沙巴 - 为什么失败 Helping a Failed Mini Swiftlet Farm in Sabah - Why it Failed





我再次回到沙巴这次是山打根。我被要求帮助这个失败的燕屋农场,这是一年多前建成的。这是一个单层的燕屋农场,拥有狗洞设计。燕屋主聘请了一位所谓的“专家”来为他建造,因为他对养燕知识甚少。花了这么多的希望和努力,它只有2个燕窝。准确来说是1个半燕窝。因为最糟糕的是其中一个燕窝是完成到一半的。这意味着燕子在做燕窝的中途就离开了燕屋。

如果人们仍然不改变他们的思维方式,失败的燕屋农场的数量将继续增加。沙巴是拥有最多失败燕屋农场的州之一。与此同时,与其他州相比,沙巴的小型燕屋农场数量最多。

“建造一个成功的燕屋农场是如此容易”的看法已经让沙巴人风靡一时。“每个人都可以拥有成功的燕屋农场”,类似于亚航 AirAsia,“每个人都可以飞” 是完全相反的。

每个人都可以飞又如何,但他们无法到达他们想要的目的地?那么,你建造了一个廉价的经济型燕屋农场又如何,但它是失败的?

我去过沙巴的许多失败的燕屋农场。他们现在在沙巴建造的燕屋农场的方式比30年前还要糟糕。我指的是技术,技能和知识。我相信目标和目的是建造一座建筑物而不是一座成功的燕屋农场。

这不是建筑商的错。他们完成了任务。他们给了你付出的价钱。你想要一座建筑物他们就为你建造了一个建筑物。你不能责怪他们,因为你是那个选择他们的人。

正如我之前提到的,一次又一次,建立一个成功的燕屋农场与价钱无关。燕子不关心建筑成本是否便宜或昂贵。最重要的是,它是如何制作和设计内部环境,以便适合它们留下和做燕窝。

大多数人都忘记了这种简单的意识形态。现在,他们依靠谁可以建造最快,最便宜的燕屋农场。

让我们来看看失败的迷你燕屋农场的问题,许多人仍然无法观察和注意。从这里你会知道为什么迷你燕屋农场往往会有更多的问题。

1)我对迷你燕屋农场没有任何反对意见。但是,我不支持迷你燕屋农场的想法,因为它的大小。 迷你燕屋农场限制飞行路径并使燕子的操纵变得困难。如果燕子不能轻易地进出,它们就不会留下来。

 2)由于尺寸大小,控制光线和气流受到限制。我们不能竖立隔板来减慢气流,因为它会限制飞行路径。换句话说,在建造的时候,您已经在制造问题。


3)这个燕屋农场使用的材料是用薄纤维素浸渍的聚苯乙烯泡沫塑料。这种材料常用于欧洲,寒冷的国家作为绝缘材料。这太人为了。它不吸受水分,也不会像天然洞穴环境那样蒸发过程。不像粘土砖吸附潮湿,缓慢释放,以稳定湿度。我绝对不会鼓励使用浸有薄纤维素的聚苯乙烯泡沫塑料。对于住宅和工业用途,可以。但不适合燕屋农场使用。

 4)其次,用薄纤维素浸渍的聚苯乙烯泡沫吸收声音并降低频率反弹。高频率的燕声被吸收到墙壁中,使得燕声不那么吸引人。它降低了燕声的效果。 (在音响行业,聚苯乙烯泡沫塑料用作隔音材料)。

5)通过我的访问经历,沙巴人很容易相信神话而不是技巧和技术。就像我说的那样,养燕并不是魔术。去学习正确的技能,学习正确的方法。这也取决于你从中学到了什么。不要让盲人领导盲人。


6)从入口洞的建造方式我们可以观察到两件事。

A)在入口洞顶部安装2尺遮阳篷的原因是为了防止雨水进入燕屋农场。狗洞的地板是聚苯乙烯泡沫塑料浸渍的纤维素,并相互连接。不像水泥可以保水并且防水。通过入口洞进入的任何水都会渗透到连接间隙中,然后流向天花板,因此所有的木板都会被弄湿。为了防止这种情况,因此建造了一个遮阳篷(一个非常糟糕的决定)。

这使得燕子在进入燕屋农场之前减速并向下飞行并平整到水平位置。这阻止了燕子以极快的速度潜入农场。正如我们在下午730分回家期间所知,大多数燕子都喜欢潜入燕屋农场。减缓它们会使它们暴露于捕食者。因此,燕子将避免留在这个燕屋农场。

B)迷你燕屋农场的长度很短(名称就是这样),使得入口洞的光线更容易到达做窝区,使其太亮。为了解决这个问题,他们增加了一个2尺的遮阳篷。如果燕屋农场变长或有分区,则不需要2尺的遮阳篷。因此,您可以清楚地看到迷你燕屋农场的问题。

因此,减小入口洞的尺寸和增加2尺的遮阳篷弊大于利。建造这个燕屋农场的人应该知道这些。



7)第二个入口洞太小。燕子很难操纵。任何形式的限制干扰了燕子跑道将阻止它们留在燕屋农场。为什么第二个入口洞这么小?答案是“建筑商正在为自己创造的问题”。 迷你燕屋农场的空间有限。它们不能形成一个大的环绕区和大的第二个入口洞,因为它会占用空间并减小做窝区的大小。其次,小的第二入口洞的目的是降低光的密度。他们不知道他们行为的后果,否则他们就不会这样做。

最糟糕的是,入口洞与互联洞平行。强光可以很容易地直接穿透到做窝区并使其太亮。


8)由于这是定制的燕屋农场场从零到建筑物,为什么出口门是3尺高。每次我们进入燕屋农场,我们都会蹲下来。除非这座建筑已存在多年,我们正在将其转变为燕屋农场,否则没有理由建造一个3尺高的出口。建筑商的技能和知识值得怀疑。


9)高音扬声器都在中间,而且只有少数。 1,基本养燕知识,燕子不在中间飞行。它们以距离墙壁1-2尺的圆周飞行。这就是为什么新的燕屋农场的第一个燕窝经常建在农场边缘的角落。通过了解这一点,应该在旁边安装更多的高音扬声器。


10)高音扬声器应放在壁角板的下面,这样燕子就会在高音扬声器的上面做燕窝,而不是从壁角板的旁边。为了节省成本,他们正在将成本压缩到极限。无论燕屋农场是否成功,它都是次要的。

11)建筑物的结构是空心钢。它看起来干净漂亮。当燕屋农场总是处于高湿度(潮湿)时,它会很快损。当燕子屎与水混合并潮湿时会腐蚀空心钢。这种燕屋农场的寿命很短。


12)小的燕屋农场往往有内部热气分配问题。与较大的燕屋农场相比,越小的区域热度越强。

为了降低温度,他们增加了通风孔的数量。交叉通风是一个问题。当炎热和干旱季节来临时,来自外面的热空气很容易通过通风孔进入燕屋农场,使内部温度不稳定。这里的通风孔太多了。建筑商通常只是遵循他们所看到的,他们不了解通风孔的目的。通风孔经常被许多人误解为冷却内部的工具。这绝对是错误的看法。

有些人可能会说,也有迷你燕屋农场是很成功的。是的我同意,但百分比很小。当竞争进入时,适者生存下去。我之前已经写过这样的文章。早在8090年代,农村地区的人们将他们的鸡和羊舍改造成了燕屋农场,其中一些人做得很好。最终,当比赛进入时,燕子将有更多选择可供选择。设计得更好的燕屋农场和那些拥有更好内部环境控制的燕屋农场将捕获所有的燕子,包括成功燕屋农场的幼燕子。

我观察到的问题还有很多,如果我在这里写的话会占用至少10页。对于那些对养燕农业没有热情并且只是为金钱符号而来的人来说,他们会睡着读这个....这不是很无聊吗?

无论如何,我已经为这个燕屋农场主人提出了改造计划。改造计划包括:

1)重新设计整个内部。
2)高音扬声器的位置和设置
3)入口洞和第二入口洞的重新调整
4)光线密度控制管理
5)温度控制和控制通风孔的数量
6)内部和外部的声音催眠吸引燕子留下来做燕窝
7)激素和香气管理。
8.......还有更多。

请记住,有很多燕子来玩耍和逗留完全不同于有许多燕子做燕窝。

大家都有好的燕屋农场。

Helping a Failed Mini Swiftlet Farm in Sabah - Why it's Failed.



I am back to Sabah again this time to Sandakan. I was asked to help this failed Swiftlet farm which was built more than a year ago. It is a single storey farm with a Dog Kennel design. The owner had engaged a so called "expert" to build it for him as he knew very little about Swiftlet farming. After spending so much hope and effort, it has only 2 nests. To be precised 1.5 nests. Worst of all one of the nests is half completed. It means the Swiftlets had left after building the nest half way.

The number of failed Swiftlets farm would keep increasing if the people still do not change their mind set. Sabah is one of the states that have the most failed Swiftlet farms. At the same time, Sabah has the highest number of Mini Swiftlets farms compared to other states.

The perception of "It is so easy to build a successful Swiftlet farm” has taken Sabah by storm. "Everyone can have successful Swiftlet farm" quoted similarly to AirAsia” Everyone can fly" is totally opposite.

So what if everyone could fly but they can't get to the destination they wanted? So what if you could build a cheap economical Swiftlet farm but it is built to fail?

I had visited many failed Swiftlet farms in Sabah. The way they built Swiftlet farms now in Sabah is worse than 30 years ago. I mean the technique, skill and knowledge. I believe the aim and objective was to build a building rather than a successful Swiftlet farm.

It is not the builder fault. They had completed their tasks. They gave you what you paid for. You wanted a building they built one for you. You can't blame them because you are the one who had chosen them.

As I had mentioned before, again and again, building a successful Swiftlet farm has got nothing to do with pricing. Swiftlets don't care whether the building cost is cheap or expensive. Most importantly, it is how the internal environment being made and designed so that it is suitable for them to stay and build nests.

Most people have forgotten this simple ideology. Now they are banking on who could build the fastest and cheapest Swiftlet farm.

Let’s examine the problems of the failed Mini Swiftlet farm which many people still unable to observe and notice. From here you would know why Mini Swiftlet farm tends to have more problems.

1) I have got nothing against the Mini Swiftlet farm. But, I do not support the idea of Mini Swiftlet farm because its size. The Mini Swiftlet farm restricts the flying path and making bird's maneuvering difficult. If Swiftlets can't fly in and out easily as a result they won't stay.


2) Because of its small size, controlling of lighting and air flow is restricted. We can't erect partitions to slow down the air flow as it will restrict the flying path. In other words you are creating problems as you are building it.


3) The materials used in this Swiftlet farm is Styrofoam impregnated with thin cellulose. This material is often used in Europe, cold countries as insulation. It is too artificial. It doesn't adsorb water and there will be no vaporization process like the natural cave environment. Unlike clay bricks which adsorb moist and release them slowly to stabilize the humidity. I definitely won’t encourage the use of the Styrofoam impregnated with thin cellulose. For residential houses and industries use, yes. But not for Swiftlet farms use.

 4) Secondly, the Styrofoam impregnated with thin cellulose absorbs sound and reducing the frequency rebounds. High frequency of Swiftlet sounds are absorbed into the wall making the Swiftlet sound less attractive. It reduces the effectiveness of the Swiftlets Sounds. (In sound Industry, Styrofoam is used as material for sound proofing).


5) Through my visiting experiences, people in Sabah are prone to believe in myth rather than skill and technology. Like I had said, there is no magic in Swiftlet farming. Go and learn the correct skill and learn the correct way you will be successful. This is also subjected to who you learned it from. Don't let the blind lead the blind.


6) There are 2 things we could observe from the way the Entrance hole is being built.

A) The reason an Awning of 2 ft is installed on top of the Entrance hole is to prevent rain water from entering the farm. The floor of the small dog kennel is of Styrofoam impregnated cellulose and is jointed to each other. Unlike concrete which could hold water and is water proof. Any water entered through the Entrance hole will seep through the jointed gap and will flow down to the ceiling as a result all the planks will get wet. To prevent this, therefore an Awning was built (a very bad decision).
This forced Swiftlets to slow down and fly lower and leveled to a horizontal position before entering the farm. This prevented Swiftlets from diving into the farm with speed. As we know during home coming at 7.30pm most Swiftlets would prefer to dive into farms. Slowing them down would expose them to predators. As a result Swiftlet would avoid staying in this Swiftlet farm.

B) The length of the Mini Swiftlets farm is short (the name says it all) making it easier for light from the Entrance hole to reach the nesting area making it too bright. To counter this problem they added a 2 ft Awning. If the farm was made longer or has partitions then the 2 ft Awning is not needed. So you could see clearly how problem arise from the Mini Swiftlets farms.

As a result, reducing the size of the Entrance hole and adding a 2ft awning have done more harm than good. The person who built this Swiftlet farm should have known all these.






7) The Second Entrance hole is too small. It is difficult for the Swiftlets to maneuver. Any form of restrictions that interfered with Bird's Runway will prevent them from staying in the Swiftlets farm. Why the Second entrance hole was built this small? The answer is "the builder is creating its own problem". Mini Swiftlets farm space is limited. They can't create a big roving and big second entrance hole as it would take up the spaces and reducing the size of the nesting area. Secondly, the purpose of the small Second entrance hole is to reduce the light density. They didn't know the consequences from their actions otherwise they wouldn't have built it this way.


Making it worst the Entrance hole is parallel to the Inter-hole. The glares could easily penetrate directly in to the nesting area and making it too bright.



8) Since this is custom made Swiftlets farm from zero to a building, why the exit door is made 3ft height. Every time we enter the farm we have squat down. Unless this building has been there for years and we are converting it into a farm otherwise there is no reason to build a 3ft exit. The builder's skill and knowledge is questionable.



9) Tweeters in the middle and there are only few of them. No.1 basic Swiftlet farming knowledge, Swiftlets don't fly in the middle. They fly in a circular motion 1-2 ft from the wall. That is why the very first nest in a new Swiftlet farm often built at corner at the edge of the farm. By knowing this more Tweeters should be installed at the side.


10) Tweeter should be placed under the corner boards so that the Swiftlets would build nests on top of the tweeters, not sideways from the corner board. To safe cost, they are squeezing the cost to the limit. Whether the farm is successful or not to them it is secondary.


11) The structure of the building is of hollow steel. It looks clean and nice. It will worn out soon as Swiftlet farm is always in high humidity (wet) . When the dropping mixed with water and moist it will corrode the hollow steel. The life span of this type of Swiftlet farm is short.



12) Small farms tend to have internal heat distribution problem. The smaller it is the more heat intensity concentrated on a small area compare to a bigger farm.

In order to reduce the temperature they increased the number of Ventilation hole. Cross ventilation is a problem here. When hot and drought season come, hot air from outside could easily enter the farm through the Ventilation hole making the internal temperature unstable. There are too many Ventilation holes here. Often builders just follow what they saw and they do not understand the purpose of the Ventilation hole. Often Ventilation hole has been misunderstood by many as a tool to cool down the internal. This is absolutely wrong perception.

Some may argue that there are also Mini Swiftlet farms that are successful too. Yes I agree, but the percentage is small. When competition comes in the fittest will survive. I had already written about this in my previous articles. Back in the 80's and 90's people in the rural areas had converted their chicken and goat coops into Swiftlet farms and a few of them doing quite well. Eventually, when competition comes in the birds would have more choices to choose from. The better designed Swiftlet Farms and those that have better internal environment control will capture all Swiftlets, including young birds from successful Swiftlet farms.

There are more problems that I have observed, if I were to write here it would take up at least another 10 pages. For those who have no passion for Swiftlet farming and only come in for the dollar sign they would fall asleep reading this....isn't this boring?

Anyhow I have come out with a revamp plan for the owner of this Swiftlets farm. The revamp plan consisted of:

1) Redesign the whole internal.
2) Tweeters position and set up
3) Readjustment of the Entrance hole and the Second Entrance hole
4) Light density control management
5) Temperature control and control the number of Ventilation holes
6) Internal and External sound hypnotically to attract Swiftlets to stay and build nests
7) Hormone and Aroma management.
8).......and many more.

Bear in mind having many Swiftlets come and play and stay is totally different from having many Swiftlets building nests.

Good Swiftlet farming All.
