                        Surveillance Solution – How To Do It?   
 
Grandstream has a full series of products for VoIP, Video and Surveillance. This article explains how to 
configure a surveillance solution for residential users or small enterprise users.  
The main purpose of such application is to ENHANCE your alarm system, avoid the unnecessary false alarm 
which could be expensive because of law enforcement involved (just two or three such false alarm will cover 
the cost of the whole equipment investment). Also in

                        Configuration  The solution is based on IP or computer network, therefore static IP is suggested. If the router used support  static DHCP, then DHCP can also be used as long as the IP will NOT change after the router and device  reboot.   Assume the user already has a home computer network or LAN in the office and no SIP server or proxy  involved in such solution. If any SIP server or Proxy involved, the setting will be different although the principle  is similar.   Following is the configurati

                        1. HT-503 Scenario     The HT503 is the key device here to connect the IP to PSTN world. The motion trigged alarm from surveillance  camera is converted to a call sent out via HT503 to the user desired PSTN number, like cell phone.     User will hear siren when receiving the call. If email is configured in the surveillance device, a snapshot JPEG  image will be sent to user configured email address.     User can immediately check back to see whether this is a true alarm by taking following actio

Fill in with exactly the same digits when dialing with that line using  analogue phone, including dial prefix, area code, etc, in required by the PSTN carrier.

Please configure only the mentioned parameters and  do not change and leave all other parameters as default:    Account Active:   Yes    SIP User ID:  Use any digits you want. HT503 just need some digits here to send to surveillance  box therefore you can put ANY digits here. Here “110” is used as example.    SIP Registration:   NO   This is very important as there is NO SIP Server involved

The user can connect an analogue phone to  the FXS port of the HT503, and use that phone (by dialing ANY digits followed by “#’ key) to call and monitor  the audio near the surveillance device installed.     If user has Grandstream video phone (like GXV3140 or GXV3000), user can configure the video phone using  settings similar to this HT503 FXS Port to make the related GS v

                        2. Surveillance Device Scenario (GXV3XXX IPC or DVS)     As mentioned previously, static IP is required in such application unless the router support static DHCP. This  will prevent IP address change once the router or the device rebooted; also if port forwarding will work correctly  only if the IP address is fixed or static.     Below (Figure 2-1) is the screenshot showing user how to configure the IP address to the Grandstream IP  Surveillance products. Here we use GXV3615 as example and the I

                        Verification    Once the alarm trigged, the user will get calls from this setup. Alarm will be trigged by Surveillance camera and  calls will be made by the HT503 using the PSTN line connected to the “Line” Port.   The receiver will hear a siren mentioning “something unusual happening in the monitored area”.   User can take several ways to verify what is happening “REALLY” in the monitored area:   1) Check the email and see the attached snapshot if SMTP is configured.

User just need to bookmark the URL or IP  and whenever alarm call received, user can just open the browser to check the bookmarked page to see the  snapshot of that surveillance device, if the router with correct Port Forwarding configured. Therefore the user  only is charged by the Mobile Carrier for the data where the snapshot frame viewed.   The format of th
