AHD/CVBS VIDEO TRANSMITTERS


Wireless transmitters for analog video

In analogue video surveillance systems, the cameras are connected to the DVR with coaxial cables or twisted pairs. If hard wiring is too expensive, or impossible, you can use these wireless transmitters for analog cameras. These devices use radio frequency to transmit the video signal generated by analogue cameras. This range includes transmitters for CVBS video as well as transmitters for high resolution 720P and 1080P AHD/CVI/TVI cameras.


Set of transmitter+receiver

These wireless video transmission systems consist of a transmitter and a receiver.
The transmitter is connected to the camera while the receiver is connected to the DVR or monitor. Both the transmitter and the receiver require 12 VDC power supply. Power adapters are not included; if you want you can choose a 12V 1A model from our range of power adapters.
The transmitter and receiver are delivered paired by factory so no configuration is required. The transmitter is generally positioned near the camera, but you can also place it at a certain distance if this allows to avoid obstacles and obtain a better signal transmission. Please note that these devices use RCA video connectors: if your camera has a BNC connector you will need an adapter.


Analog or digital video transmission

Our range of wireless transmitters ofr analog cameras includes models with analog RF transmission and models with FHSS digital transmission. Digital transmitters convert the video signal from analog to digital between the antennas and guarantee a noiseless and stable transmission , better than analogue models. They also provide a remarkable immunity against radio interference and coded communication. We recommend the low cost analog transmitters for short distances with very little obstacles, for example on vehicles or boats. For more demanding applications we certainly recommend the digital transmission that guarantees a more stable and clean signal. There is also another important difference between these 2 models: in analogue transmission the signal of a transmitter can be received by several receivers, while in the digital transmission each transmitter is paired only with one receiver.

FHSS protocol

For CVBS and AHD up to 1080P

These transmitters and receivers are available in different models that support both traditional CVBS analog video and AHD / CVI / TVI high resolution analog formats, up to 1080P (2MP). With our AHD transmitters you can connect the cameras of a modern analog system without wires, still keeping high resolution. These transmitters have extra low latency, less than 100ms, much lower than any of our WiFi wireless cameras.


Transmission range up to 300 m.

These transmitters and receivers for analog cameras allow line-of-sight transmission range up to over 300 meters between the two antennas, according to models. If there are walls between the antennas you can reach 4-5 rooms of distance, depending on the size of the obstacles. These video transmitters are ideal for the RESIDENTIAL CCTV, but also to be used on VEHICLES , BOATS, LIFTS AND OTHER MACHINERY where passing cables between camera and monitor/DVR can be a problem. You can use up to 3 transmission systems in the same environment without them interfering with each other. AHD models do not have this limitation, allowing up to 26 transmitters to operate in the same area. In digital transmission systems you can pair the transmitter with the receiver yourself, with the built-in pairing button, while in analogue transmittion models channel 1, 2 or 3 must be factory set.


Useful optional accessories

These analog video transmitters come standard with omnidirectional antennas. These antennas transmit at 360° and do not need to be oriented in a particular direction. Pay attention to shielding objects, such as thick walls or metal surfaces, that radio waves go through with difficulty and do not install the transmitter in a metal box because the transmission would be shielded. To deal with particular installation scenarios you will find in our catalog 30 cm to 1 m. extension cables to move the antenna. They may be useful, for example, for getting the antenna out of a case or going around a wall. If you use these cables you should also buy our 6dB high-power antenna , 173 mm long, which you can use instead of the standard one to increase the transmission performance.


TIPS


Place the transmitter in the camera junction box

The transmitter is normally placed near the camera. It can be a good idea to place it inside the camera's junction box. You can place the transmitter inside plastic containers without affecting the transmission. If you place the transmitter in a metal box, you need to make a hole to let the antenna out. If you want, among our accessories you will find antenna extension cables. Both transmitters and receivers are water-proof. The kits with digital transmission allows you to power both camera and transmitter with the same adapter becouse they come with DC input/ouput jack. For analog transmission kits you may use a DC splitter cable which is available among our connectors.
